KEXEC works in the nook tablet - Barnes & Noble Nook Tablet

I managed to execute a customized kernel. But it hangs in somewhere.
The main trouble is l2 cache. The l2 cache may crash the kernel in the somewhere. I am inspired by hkvc. http://forum.xda-developers.com/showthread.php?t=1427610
Did you meet this problem?
Here is output from uart:

you could try the l2 cache flush logic in my linboothkvc
Hi Highfly,
I haven't really looked at kexec directly, because I figured/or_rather_think(haven't had time to patiently go thro it, I am bit lazy and impatient wrt reading thro documents or others code and so, unless I have to) it has too many dependcies or a few kernel space things distributed here and there and few userspace stuff distributed here and there logically and so on and so forth. And also because I was more interested in exploring and facing the possible problems on my own so that I learn more about the new Arm cores and SOCs.
If you are facing any problem with L2 cache, then try the l2 cache flush stuff I have put in my source package and see if it helps. It is a much much simplified version of what is there in sleep file and the PL310 trm, because I don't really want to wakeup from a sleep, so I or for that matter, even you don't have to worry much about saving stuffs (i don't mean everything here, yes some stuffs you have to save from cache to memory like the code you want to run in the new environment etc) and other stuff. Also I take care of disabling the 2nd processor before I do the cache related stuff, so that way also I don't have to worry about syncing across them (There is a small corner case, there in my flow, but I haven't seen it triggered till now, and I have a simple way of bypassing it for now, so I am not worrying too much about the 2nd processor).
Or you could also try disabling the L2 cache specifically before exiting from existing kernel (which I am not doing by the way, rather I fully disable all cache thro cp15), based on what I have read, disabling L2 cache specifically is supposed to make it automatically do a safe flush i.e clean followed by invalidate in a automic manner.

UART Output/ Bootloader hacking/ Kernel Debugging on AT&T SGS2

Hey, one of my buddies got a SGS2. I was able to play with it for a bit. I sterilized the Serial numbers. This was recorded on Linux, then transfered to Windows, so the formatting was off. I had to use some Microsoft Word Regex in order to get it to format right.
here's the full UART Logs

There's some new ones in this 3.1 version of Samsung SBL
* crc
* log
* sud
* upload
* emmc
I think Upload allows a dump of all partitions. Also, Keyread allows testing of button presses, Volume - =0 Volume + = 1, Power = 2
I couldn't get a FULL debug log in the time I had, but I managed to get some kernel output.

Would be interesting to see the logs from a boot with the flash counter incremented (yellow triangle) to see if it's logged and what it's keying on.
Hi Adam,
Nice to see u here on this forum , hope to see some of your great work here on S II.
This is only possible using UART.

You can reset the counter via UART
What ROM did you dump JH7/KJ1/KJ2 ?

Jig will reset it too - or will UART reset it even on the J2 bootloaders?

Can you flash back the J1 bootloader with ODIN? I'm willing to try this.
Another big player from the captivate scene......I feel more comfortable fashing the SGS2 now that AdamOutler is in the house to help clean up the mess lol
Yay, I'm the first dumbass to brick his I777. Kids, don't run the "emmc" command.
FWIW, when USB is connected and battery plugged in, I get this device:
Bus 001 Device 011: ID 04e8:1234 Samsung Electronics Co., Ltd
Which ModeDetect says is Unbrickable Debug mode...
Ah, I thought for a second I miss clicked forum and came to captivate one.
Happy to see you here, hope you will get your own attsgs2.
Thanks for spending time and sharing findings!

Yeah. So, you should try the SMDK Upload Tool.. this is good. this means you've established that UnBrickable Mod is possible on this device.
Now I need one for teardown.
Is it dead bricked? remove the battery and hold power for 10 seconds, then put back in the battery and hold it for 10 seconds. should turn on normally.
emmc usually means external MMC... try making a boot disk using the Fusing Tool. I bet it will work.

That's what happens when it tries to upload a larger file then memory can handle.
The HIBL is a Hummingbird Interceptor BootLoader. We could use a Exynos interceptor bootloader.
Let me contact Rebellos and get him in here. That polish Hairy Potter can probly wave his magic wand over a memory dump and have it doing the hokey-pokey. He is busy and recovering from a serious loss while trying to get his device into the mode which your device is in currently... he could probly use some donations.
We will need someone with a working device to do a memory dump...
1a) I need few different bootloader images from I9100 and similiar SGS2 series models (I777 or whatever is it called for eg.), can you guys post these here?
1b) If you notice some weird files in ROM releases, like *.elf - post these too! These are very helpful in reversing stuff. Samsung released these for S8500 and S8530 bootloaders so here is also a chance.
2) If anybody has got rooted Exynos based device and some know-how about using SU functions - I need iROM dump.
The procedure should be 99% the same as in there http://blog.maurus.be/index.php/2011/01/samsung-i9000-irom-dump/
Just grab viewmem ARM binary http://blog.maurus.be/wp-content/uploads/viewmem and use script posted there. With small modification!
Instead of
/tmp/viewmem 0xD0000000 0x10000 > /sdcard/iromdump

try
/tmp/viewmem 0x00000000 0x10000 > /sdcard/iromdump

if it doesnt work then try this
/tmp/viewmem 0x02000000 0x10000 > /sdcard/iromdump_mirror

One/both of these should produce 64KB iROM image.
3) WANTED:
- newer manual than this one: https://dl.dropbox.com/u/36177984/SEC_Exynos4210_pulbic_manual_Ver.0.00.01.pdf (we don't know if it does exist)
- Exynos 4210 Application Notes
- Exynos 4210 Secure Booting Guide
And so on.
Thank you.
Don't fear the reaper.
//edit:
Also SGS2 series seems to be more unbrickable than SGS, I bet PBL has got functionality to boot from SD card. I don't see other reason why PBL would mount it before trying to look for SBL.

Disassembly will show.
I'm going to see about getting a replacement tomorrow as this is my daily driver. So I won't have it around to test anything. However, once I'm up and running again I'll try to get iROM dumped.
Meanwhile, tonight I'll see if I can fuse a 9100 PBL and SBL (they're supposed to be mostly compatible) to a microsd and test the external SD boot theory.
edit:
Hmm, looks like the fusing tool needs a monolithic PBL and SBL. My attention span for reading Google translated Korean forums is shot.
That's probably not necessary anyway, because I think the confusion here over "emmc" is due to the SGS2 using eMMC (embedded MMC) for the boot device as opposed to the i9000 which boots off of parallel oneNAND. The SGS2 is always booting off of MMC, it just happens that it's soldered down.

[MOD]UART Debugging Connection

Introduction
Why is UART useful? It's a debugging tool. During the boot sequence on most computers, you see a splash screen. On most computers, you can hit 'ESC' to see the diagnostics in the background and then press a key like 'F2' to jump into the BIOS and make changes. On our devices we don't have that option.
On the Nook we have U-Boot which functions as a BIOS. We press 'Space Bar' to get into the U-Boot options. UART allows you to get into the U-Boot and make changes, as well as view the logs as they are generated. See the following code block for an example output

You will need
In order to get started you will need some things. Here's what you will need.
Torx T5 screw driver (the star kind)
Soldering iron ( any soldering iron)
Case opener tool ( or guitar pick or something small and plastic)
30-40 AWG wire (small wires)
1.8V UART to USB converter (Like The Bus Priate)
Tweezers (Makes it easier to handle small things)
Most of the tools and parts used can be obtained at Lowes or Radio Shack
For a UART device, I recommend The Bus Pirate. The Bus Pirate is known as "The Hacker's Multi-tool" and it is useful for alot more than just UART. It is an Open-Source, Open-Hardware, community supported tool. You can get it from SeeedStudios.com for $27.15.
Instructions
There are several ways to set up UART. Here is how I set up mine.

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Disassembly
If you have an SDCard inserted, remove it.
Remove two(2) T5 Torx screws securing the back cover to the unit
Using the Case Opener tool, pry the rear cover off the unit. It is held on by small plastic hooks. They are fairly durable and I have not broken any in several removal and installations.
Remove ten(10) T5 torx screws from the metal case which secure the front cover
Image 2:
disconnect the battery and the volume control swich connections which are accessible through holes in the metal case.
Remove the front cover using a case opener tool or your bare hands, whichever is more comfortable for you
Remove the board and LCD from the metal case
Modification
Image 3:
Locate the UART RX and TX lines on the board shown in Image2.
You can hook your UART device to this directly, RX to TX and TX to RX, or keep reading and I'll show you how I set mine up. so..
Stop here and use UART or continue on for a cleaner method
run 40 awg wire to a piece of perf-board, about 8 holes wide.
Using 20 awg wire, make a loop on the perf-board which joins two holes in two spots on the small piece of perf-board
attach the UART RX
Image 4:
Route the wires along the board and tape them down
Use epoxy to mount the perfboard. It should be mounted at a very slight downward angle. Set something under the board while it dries. This gives room for the case to close.
Reassemble the unit, Assembly is reverse of Disassembly.
Image 5:
Hook up RX, TX to your perf-board hooks and connect ground to the metal case.
Image 6:
You will now be able to talk to your UART device using
Baud: 115200
Bits: 8
Parity: None
Stop Bits: 1
Voltage: 1.8 (open drain)
For the Bus Pirate, get it working in a termianal and use the following settings:

Conclusion
For those of you helping with security bypass methods, this will surely be useful as it will tell you when a secure failure is encountered. For those of you who want to experiment with U-Boot or a cool electronics project, I'd encourage you to try this. There's not alot that can go wrong because the board is well built and fairly heat resistant and the tools/parts used in this mod are available from several sources.
I hope this was informative and/or interesting for you to read.
Thanks to pokey9000 for pointing me to the right area.
A few lines before the kernal starts loading, it has bootcnt 2. What does this mean and what happens if it is modified? Or is any modification break the secure CHAIN?
Also, what would happen if it didn't autoboot in 0 seconds and you could hit the spacebar?

That's the number of boots since the counter was reset. After 8 failed boots, the device will go into recovery and restore all firmware.
this is great! I have been looking at my arduino and my pandaII (.netMF) dev boards and my tablet for a few days now.
Glad I dont have to pull out the logic analyser and find those pins..

that's exactly what I did...
Adafruit's FTDI Friend should also do the trick, $10 less.
I changed up my UART connection. I feel this is much cleaner and runs less wire through the nook. This makes it into a really good development device.
This new setup is made with a piece of perf-board from Radio Shack and it's held onto the nook using double-sided tape. Here are some pictures:
The wires are routed through the crack in the back cover and run to the same points mentioned in the Original Post. The 3rd connection (middle) here is Ground. Ground is the point on the board closest to the edge and furthest from UART TX in the staggered group of pins..
I thought I'd update this... I though I'd update this after a few weeks of working with it. The external connection works very well. It is easy to remove and replace if required with just 3 solder joints if required. The external perf-board is very unobtrusive, and does not interfere with operation.
I also found a case that works well with this modification. it's called "Mini Suit" for Nook Tablet.
If you go with this method and need a case, Mini Suit will suit you.
Adam,
In picture 3 you have a diagram that shows the pinout for uart tx and rx on the nook tablet (appears to be the left two pins of the 4 in the diagram), but if you look closely at picture 4, the top wire appears to be soldered to the top right pin rather than the top left pin as show on the diagram in picture 3. Is this just an optical illusion?
Thanks Again for all you do on these forums.!

Replacement for Bus Pirate
Hi Adam
Good day to you.
I would like to setup my own Uart devices for Samsung Phone, however, not able to locate the Bus Pirate devices as mention in your thread.
but i found a USB to RS232 converter as per attach PDF file.
would you please help to check on it? is it possible to setup the UART setup use on Samsung phone?
if can kindly help to give a detail guide connection setup from PC USB to Phone.
appreciate you help.
thanks

This should really go into the Samsung forum for the phone you're trying to get to, however here is where you can buy a bus pirate.

Fixing NT stuck with CWM, restore / update won't work

Many people are getting what they are calling a bricked Nook tablet that won't boot or restore an OS. Often when they boot into CWM (from internal or SD) they get errors on screen, or possibly after an attempted install they show in the advanced / log
E:Can't mount / cache/recovery/command/
E:Can't mount / cache/recovery/log/
E:Can't open / cache/recovery/log/
E:Can't mount / cache/recovery/last_log/
E:Can't open / cache/recovery/last_log/
failed to open/sys/class/android_usb/state: No such file or directory
This is actually an extremely common issue it seems. Basically its' quite likely you're partition map has some how been damaged.
Firstly just make sure you can't install an update or restore an old backup from SD, if that still fails and you end up straight back in CWM
All you need to do is download the parted binary HERE extract it from the archive and push it to your device or even just put it on an SD
ADB into your device and run the binary with the following command (you'll need it to be the accesible path or you can just be in the directory where it is)
parted /dev/block/mmcblk0 print
It will most likely show up with an error and ask if you want to fix it. Just say yes and let it do its' thing.
After it completes, reboot your device and see if you still get the same errors, Attempt to install CM7 once more.
If it still doesn't work, run the parted command again then download Adams total wipe and run that. It'll reset your device back to total stock. The parted command will repair the partition table and adamoutlers software will upload all the required software to the correct places for it all to work
Hope that helps!
If you get stuck feel free to give me a shout

NT full brick...unable to recover.
My NT is suffering from the CM7-SD format brick problem.
I have hunted high and low for instructions on how to get ADB to work on a bricked NT. My NT is in a state where the only thing that boots on it is an SD-based CWM, but when I plug the NT into a PC, no matter what I do, CWM recovery starts up and the PC detects the unit as disk drives. ADB will NOT find the unit. I have tried on two separate Win7 machines...same problem on both.
I have also tried using Adam's total wipe fix, and while linux boot, the full wipe just hangs forever on the first step (zeroing MLO).
I am not sure I have the right USB drivers...basically, I'm using the ones I had for my long-gone Nook Color.
Can anyone offer me some help?
Thanks.

It's not actually caused by formatting SD on CM7 any more. you could happily format your SD all day, although we still recommend not formatting anything at all via the NT.
If you have CWM you should have access to ADB, the probably reason it doesn't work for you is that you need to tell your computer what the id is on the device so that it can recognise it. What operating system are you using?

Thanks, Celtic.
I'm on Win7. I have 'adb_usb.ini' in folder:
C:\Users\<myname>\.android
And the 'ini' contains 0x2080.
More details...

Here's a brief history, as best I can recall, of how I got where I am with my NT.
1. Installed NT CM7 about a week ago. All worked well until I noticed Kindle app misbehaving by not flipping pages on a book. I tried same book on two other android devices, and both worked fine. So...
2. In a complete act of stupidity, I went into 'Storage' on the NT, and noticing that there were 3 sections listed there (whose names escape me, but something like 'Internal SD', 'SD' and 'External SD'), I formatted all 3 (yup, dumb).
3. I shut down the NT (10 second press of power), and from there on in, tablet hung at 'N' screen. I manages to get CWM to start, using a combination of buttons I now don't recall (Power and Volume Up, perhaps?).
4. For reasons I can only describe as lunacy, I used Recovery to format everything it listed as format-able (under Mounts/Storage). From this point on, the tablet would not boot at all, not even back into CWM Recovery.
5. Thru online searching, I found an image for making a bootable CWM Recovery, which I created and used successfully to boot into recovery. I used it unsuccessfully to try to re-install CM7.
6. I then tried getting an ADB connection so I could try the various other fixes offered online, but have been completely unable to get a connection. I followed the instructions found in XDA thread ID 1424563 (sorry, I'm too junior to have link-posting permissions), but the thread assumes I can get to the NT's settings to turn on debug mode, which I can't.
7. As mentioned, I also tried Adam's full wipe/restore, but it hangs on phase one (zeroing MLO).
That's the crux of it, for what it's worth. I think my big issue right now is not being able to get ADB to work with it. If I could, I could try the partition command you gave in the OP.
Thanks for any help or ideas...

you should have damaged the partition tables, so please make a CMW card first, and then you can use adb shell to repair the partition table.
you can refer to this thread:http://forum.xda-developers.com/showpost.php?p=22157605&postcount=25
If that older driver you have don't work, you can find a driver in this thread. (I don't know if they are the same as color or not TBH)
Use the USBDeview to rid yourself of anything aldroid related, anything Google related, and any mass storage devices. Restart PC, then plug your NT in. (This is how I had to do it...many times)

Thanks, ms, but as I mentioned, I am completely unable to get ADB to work. It will not find the tablet. When I plug the tablet in to my Win7 box, the installed CMW card boots the tablet into recovery, and the PC detects it as disk drives (as seen in Win7's Device Mangler).
Quick progress update...

The old drivers and instructions you linked to worked...ADB now finds my NT! Thanks much!
Now...
I did the 'parted' thing, and while 3 or 4 errors were reported thru the process, it stated it completed successfully. I then rebooted with my CWM Recovery SD card and attempted to re-install CM7. The installer completed quite quickly and without errors, but it did not work (as I suspected it wouldn't, given how fast it executed). I then ran 'Brick_fix.zip', and it, too, completed successfully (well, except for the ping at the end), but I was unable to install CM7. So...
I'm now on to Adam's fix (note in the OP) and I'm glad to report it's working now. It got past the first stage (zeroing MLO) and is in the middle of 'flashing factory'. Sweet!
I'll report back in the morning, hopefully with good news. Thanks so much for the help, everyone.

Sorry I didn't get back to you last night, I had already gone to bed, looks like you've already got the help you need though. If the wiping had started to work you'll be fine lesson learnt though, DO NOT FORMAT ANYTHING ON NT
Let us know it's fixed (which I'm sure it will be )
Bad news...

Well, the news is bad this morning. As someone mentioned in Adam's post, during the install, the screen went blank, so I left it for about another half an hour, then powered the device off and restarted it. All appeared OK, as the B&N firmware stated that it was clearing data, but that process froze for a long while, then a message popped up stating "Please restart your device and try again. If you encounter the same issue, contact technical support at blah, blah, blah." I restarted...same message. Over and over.
I tried the full wipe no less than 4 more times, preceding each attempt with a 'part' command, but the full wipe, for some unknown reason, stops about 60 seconds in, and pops up what appears to be a windowed 'ls -al'. I tried two different class 4 SDs in the 4 attempts...same for each.
Not feeling hopeful at this point.

Here's the results from my 'part' command:
Code:
~ # parted /dev/block/mmcblk0 print
parted /dev/block/mmcblk0 print
Model: MMC SEM16G (sd/mmc)
Disk /dev/block/mmcblk0: 15.9GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 131kB 262kB 131kB xloader
2 262kB 524kB 262kB bootloader
3 524kB 16.3MB 15.7MB recovery
4 16.8MB 33.6MB 16.8MB boot
5 33.6MB 83.9MB 50.3MB rom
6 83.9MB 134MB 50.3MB fat32 bootdata
7 134MB 522MB 388MB factory
8 522MB 1164MB 642MB ext4 system
9 1164MB 1611MB 447MB ext4 cache
10 1611MB 2684MB 1074MB fat32 media
11 2684MB 15.6GB 12.9GB ext4 userdata
Note the fat32 and ext4 file system designations for various directories (is directories the correct word?). On page 6 of Adam's full wipe thread, user 'howcansheslap' shows the output of his/her 'part' command, and the file system in his/her output is all blank. Perhaps not coincidentally, my full wipe process stops on processing 'bootdata', the first item listed as fat32 above, and displays the windowed 'ls' of folder 'bootdata'.
Any thoughts on the relevance of this info?
Thanks all.

Turns out the full wipe *was* working. The trouble is, my impatience got the better of me. Adam's wipe process does not provide a whole lot in the way of progress feedback, and in fact, it can be 5 minutes or so before you see anything meaningful on screen. Best advice: give the process a full half hour to complete and don't assume that it's hung/stopped working just because you see virtually no progress reports. Note also that if you touch the screen anywhere during the wipe, any progress bar that may or may not have been present will probably disappear, and you won't see another one displayed for possibly several minutes.
My apologies to all for subjecting you to my own impatience, and a big thank-you for all the help.
I spoke too soon...again.
The full wipe/restore completed successfully, but now when I start the tablet, I get taken thru the B&N setup process and at the stage where it asks me to login to my B&N account, I get:
Error
Sorry we're having trouble setting up your NOOK. Please shutdown the device and try again. If the problem persist, contact Customer Support at...
Well, the problem has persisted all day. I have even done the full restore a couple of extra times. And the tech support line just keeps telling me they're unable to process my call at this time.
I am definitely able to login to my B&N account thru my PC, so I've got the credentials right.
Has anyone encountered this before?
UPDATE: I followed the instructions for bypassing registration, found here:
http://nookdevs.com/NookColor_Factory_Mode/Skip_Oobe
This allowed me to get into settings and 'erase/unregister' the device, but alas, still no joy after a reboot.
back from brick to Nook Tablet
Hi to all, i had the same problem as imacmill onlly i've idiotly erased the "SD card" the 1 gb amount.
After restarting the NT did not boot. I've entered in CWM recovery... and had the same problem (***up my partition table)
E:Can't mount / cache/recovery/command/
E:Can't mount / cache/recovery/log/
E:Can't open / cache/recovery/log/
E:Can't mount / cache/recovery/last_log/
E:Can't open / cache/recovery/last_log/
after agonizing 3hrs we succeeded to repair my NT via parted with ADB.
I've attached the log from adb.

Sounds like its not actually booting the SD card. Try powering off completely and the put SD card in. Connect power cable and see if it boots. It could also be your SD isn't written correctly. Could be worth you downloading the latest cm7 SD image from the dev thread. See if that boots.

cwm wont run
Thanks for the reply! i have tried all combinations of power,"n", vol up, and vol down, holding not holding all combinations of buttons and also the 8 failed boot buisness, plugging in to wall outlet, plugging in to pc... no changes yet, still "n" symbol on screen, then pic of box, hang. i am downloading the latest cm7 build and downloaded the installer located
here: http://forum.xda-developers.com/showthread.php?t=1000957
per your suggestion. im now making ramen, because the download says 52 min left. I will check back soon. thanks again.
I have followed the instructions and still no boot to cm7. still "n", then pic of box, hang. darn. any ideas?
Can't ADB. PLEASE HELP.
I am having trouble with my nook tablet. It will not boot an OS, and it just hangs at CWM. I am trying the original solution posted by CelticWebSolutions, but I am very new to all of this, and I can't get my computer (windows 7) to recognize the nook as an ADB device. I have no idea what USBDeview is, or where to get it. I have also managed to kill my 2 best micro SD cards. They were 32 gb cards, and when I tried to install CM7. If possible, I would like to just get back to a factory Nook Tablet. If anyone can help me reach a solution, I would be happy to donate.

Can you get into CWM?, Have you tried Adam's total wipe method?, what OS did you have when you bricked your device? What exactly have you done to it? We need more details in order to help you.

How to find out what's causing lock-ups?

I haven't managed to find a ROM that doesn't freeze up on me. I suspect that it may be apps, rather than ROMS, that are causing this, because it also happens when I revert to a stock ROM.
Can anyone recommend a way of diagnosing which app(s) may be causing the crashes? There's usually no regular pattern in behaviour - i.e. it happens in a variety of different situations/apps
mate apps generally dont cause lookups..its your settings that do..apps only forceclose..thats it...if you are on any custom kernel then its a 90% chance that whats causing your lock ups is your undervolt settings...otherwise..flash again with all the wipes...if you dont wipe then lockups are gonna be a very common occurance..backup all the stuff..!
Nah man. Apps, some apps, definitely cause Wake up's dude.
The most popular application to check wakelock's is BetterBatteryStats. And additionally i can tell you some wakelock's are also caused by Ad's, yes you read it right, damn AD'S. To block them please use AdAway, free in Play Store.
What are you going on about wakelocks for?
the thread is about lockups mate not wakeups!

I never do undervolting or any CPU mods, so it can't be that. I also routinely wipe, clear the cache and dalvik cache every time I flash a ROM. That's why I figure that it's probably apps doing things in the background that are the problem.
what about factory reseting via recovery and formatting system,data and cache in recovery under mount and storage option...wiping dalvik and cache dont reset or wipe your device..perform all the above mentioned wipes and your problem will hopefully end!
and if your are on any custom kernel..try increasing the stock volts by 25..!give it a try...!
Will "formatting system,data and cache in recovery under mount and storage option" wipe the contents of the internal SD card?
no...i do it always..never it has touched either of my sdcards...!
Should I do all of that AFTER flashing or before?
do it before flashing...and try to let the rom boot and run for 30 mins or so before going back and installing any mod or kernel!
Next time it happens, grab a kmsg as soon as you reboot:-
In a terminal editor enter the following:
su
cat /proc/last_kmsg > /mnt/sdcard/last_kmsg
and post it as an attachment to this thread. Might yield some clues as to what the phone was doing when it locks up/crashes.

Ok it's just crashed again - this time while copying a large folder from the phone to a PC over USB. I rebooted, downloaded a Terminal Emulator from the Market, then generated the attached "last_kmsg" file as instructed. Please let me know if this gives any clues.
...sorry...here's the attachment...
Just had another lock-up. This time the phone got quite warm, and drained from 97% battery to 11% in 1.5 hours, so something was chewing up the CPU. Here's the last_kmsg output from immediately after the reboot:

Woot! Nice work! So you've managed to boot into a Debian build? Damn nice work! Do you know if its possible to do that without having access to Android in the first place?
Like from UBOOT?
Yes i used to uart.
Write this command to uboot:
setenv bootcmd "run start_autoscript; run storeboot;"
setenv start_autoscript "if usb start ; then run start_usb_autoscript; fi; if mmcinfo; then run start_mmc_autoscript; fi;"
setenv start_mmc_autoscript "if fatload mmc 0 1020000 s905_autoscript; then autoscr 1020000; fi;"
setenv start_usb_autoscript "if fatload usb 0 1020000 s905_autoscript; then autoscr 1020000; fi; if fatload usb 1 1020000 s905_autoscript; then autoscr 1020000; fi; if fatload usb 2 1020000 s905_autoscript; then autoscr 1020000; fi; if fatload usb 3 1020000 s905_autoscript; then autoscr 1020000; fi;"
setenv upgrade_step "0"
saveenv

No, the image will not pass the burning tool vertify.
I think you can use the amlogic burning tool only with uart. In uboot write "update" command.
