Whats the right way of compiling a module for the Atrix kernel?
I'm currently using the stock android 2.6.32.9 linux sources and the Atrix's config, although I can't get the kernel to agree with the modules I'm trying to build.
Motorola didn't use froyo sources to compile the kernel, they used vanilla 2.6.32.9 to do it.
The last problem is that modules are built as ARMv5 instead of ARMv7, probably since there is a patch setting the system type to Tegra 2.
Compile Atrix 2.3.6 kernel mods
I've grabbed the source for the 91 kernel source since the 141 kernel source has not be release. I need to get iso9660 and udf file system support.
I've followed this thread on compiling the kernel http://forum.xda-developers.com/showthread.php?t=1141506
I can successfully compile the kernel and the kernel modules, but I keep getting an invalid module format error, what's a revised way for compiling kernel mods?
[email protected]:/opt/dev/kernel modules/kmods$ sudo insmod ext4.ko
insmod: error inserting 'ext4.ko': -1 Invalid module format
[email protected]:/opt/dev/kernel modules/kmods$ sudo insmod udf.ko
insmod: error inserting 'udf.ko': -1 Invalid module format
My end Goal after I get the kernel mods working is to compile a kernel with swap support.
Thanks for any help rendered.
When you get the insmod errors try looking at dmesg at the tail end of the log, usually that error means the version string doesn't match what is baked into the kernel.
Cheers!

The general rule is that you do not want to enable swap on a flash based file system, but that is up to you.
Are you getting the module load errors against your own kernel, or are you trying to reproduce the stock kernel and your modules fail when loading against the real stock kernel?
If the latter, there are many things to look at. First would be your cross tools. These could easily produce incompatable code. But if the error is just a symble not found, then most likely your kernel config does not match the running kernel.
EDIT: missed the error messages, but it still is about the same answer. The compiler is generating the wrong code either becasue it is different from that whcih generated the running kernel, or the config options comming out of your kernel tree are not matching.
Have you tried actually running your kernel?
Thanks so much for the advice from the two of you. These are my dmesg errors. they pop up right after I enter the command: insmod isofs.ko
[505123.289798] usb_ether_get_stats
[505123.322414] isofs: no symbol version for module_layout
I'm new to kernel work. I used the config from my phone directly, it was located at /proc/config.gz
I used the cross compilers as defined in the post I linked to in my first post. unfortunately I don't have the source to 141, just 91, what's on source forge from motorola. I don't know if they did any changes between the two, but the release version was slightly different between the two.
I'm okay with burning through external sd cards for the sake of having more browser tabs open, and an overall more responsive system.

I saw in one thread that you have to compile the kernel first before the modules. I did that, and now I'm getting a new error:
[506616.823352] usb_ether_get_stats
[506616.867837] isofs: disagrees about version of symbol module_layout
seems to be a version conflict. do I have to inject that in on compile?
Have a look here: http://forum.xda-developers.com/showthread.php?t=1014010
Not the modules you are talking about, but same error.
For cifs/smb I ended up using smbnetfs, taking advantage of the fuse fs already in place. /dev/fuse has to be set group fuse with rw for group, and user adas has to be in group fuse.
Cheers!
i followed this tutorial

so whats this warning and why am i getting it?
everything else goes smooth and i get the zimage fine
i am using ubuntu 12.04
also since only play,neo and arc are mentioned in the link, what kernel source is to be used for the mini/coconut etc family?

Good morning from Germany!
I would like to recompile my kernel on the gt-s 5300 device, so that i could install / setup some application and modules.
Basically i would like to enable the usb gadget on this android device, as far as i am informed, a kernel recompile is needed.
i have done a few kernel recompiles for linux systems, but never for a android smartphone.
maybe someone could point me to the right path ?
thanks all for your help!
kind regards

Hello,
Yes I have read your post - and everything worked fine.
My question now is how to get my own module to be compiled?
I have my sourcecode but not sure where to place the module and what references in which Makefile have to be done ..?
Thanks for your help.
Kind regards
Stock GT-5300 kernel built, but won't boot
I've been able to create a zImage from the GT-S5300 open source kernel code, using the bcm21553_cori_04_defconfig as indicated by the accompanying readme file.
However, when I use this kernel to create a boot.img and download using Odin, I get a quick S5300 startup screen, then nothing.
At this point, I'm just trying to build a stock kernel, no modifications. I'm looking for helpful hints on where to find any debug or error messages that will help indicate what is going wrong. I can use Odin to put the prebuilt stock kernel back, and it boots ok once again.
I've compared my boot.img with a stock boot.img (samfirmware sourced), and they are similar in terms of addresses and pagesizes. The ramfs file is also stock, taken from that same stock boot.img. The built kernel is a bit larger than the stock and I'm not sure if I should expect my built kernel to be exactly the same size, or if it's ok for it to be a few KBs different.
Any other parameters or configurations that I might be missing or should check? (And to samsungkid, were there any special steps that you took?)
Thank You!

No errors reported anywhere that I could find, but thanks for the response.
UPDATE: I resolved my original issue: toolchain was wrong. The readme from samsung tried to tell me, but I refused to listen... Once I changed to the Code Sourcery toolchain, the zImage loaded fine.
But back to samsungkid's issue....
I believe he is still trying to get his own custom module compiled into the kernel. I know that building a module separately as an LKM would work technically, but I don't know if that makes sense for the use case.

Thanks for every information you can give me !
Maybe I need to give you more details, so:
I downloaded the corresponding kernel for my samsung device.
Then I unpacked the file and opened the readme file, which states:
HOW TO BUILD KERNEL 2.6.35 FOR GT-S5300
1. How to Build
- get Toolchain
Visit http://www.codesourcery.com/, download and install Sourcery G++ Lite 2009q3-68 toolchain for ARM EABI.
Extract kernel source and move into the top directory.
$ cd common/
$ make bcm21553_cori_04_defconfig
$ make
2. Output files
- Kernel : kernel/common/arch/arm/boot/zImage
3. How to make .tar binary for downloading into target.
- change current directory to kernel/common/arch/arm/boot
- type following command
$ tar cvf GT-S5300_Kernel_Gingerbread.tar zImage

So I downloaded the appropriate toolchain and created my directories under /root/projects/android

In the directory infofiles are only the readme files from Samsung.
Kernel contains the extracted files from the archives, downloaded from Samsung.
tarballs contain all the tarballs meaning the kernel.tar.gz and the toolchain.tar.gz
toolchain contains the extracted files from toolchain
I then do all the thinks written in the readme file:
[email protected]:~/projects/android# cd kernel/common/
[email protected]:~/projects/android/kernel/common# make bcm21553_cori_04_defconfig
#
# configuration written to .config

no one ?
Have you EXPORTed variables to point to the compiler directory?
A guess, but is the error message saying it cannot find the cross compile toolchain? Generally, you need to either export a couple of variables, or add them to the make command line. Something like:
ARCH=arm SUBARCH=arm CROSS_COMPILE= /home/yourhome/toolchains/.../arm-none-eabi- make
Hope it helps.

Thanks.
I added the path to the toolchain directly into the $PATH variable...
Even tried your above statement - the same error again
Maybe need this...
You may need to edit the Makefile:
export KBUILD_BUILDHOST := $(SUBARCH)
ARCH ?=arm
#this is original ---> CROSS_COMPILE ?=/home/aniruddh/sgy/arm-eabi-4.4.3/bin/arm-eabi-
CROSS_COMPILE ?=/home/your_user_name_here/arm-2009q3/bin/arm-none-eabi-
CROSS_COMPILE ?= $(CONFIG_CROSS_COMPILE:"%"=%)
Then you will run 'make' without export any variables.

Hi, good start. In fact I have, the differences in the kernel options between C6833 and C6843 (Brazilian model with digital TV) are:
Code:
47c47
< CONFIG_MACH_SONY_TOGARI_BRAZIL=y
---
> CONFIG_MACH_SONY_TOGARI_ROW=y
275d274
< CONFIG_ISDBT_TUNER_SMTEJ11X=y
325a325,327
> CONFIG_TOUCHSCREEN_CLEARPAD=y
> CONFIG_TOUCHSCREEN_CLEARPAD_I2C=y
> CONFIG_TOUCHSCREEN_CLEARPAD_RMI_DEV=y
Yes, I don't know why the Clearpad touchscreen is enabled for the C6833, but not for the C6843; I think it's just garbage (perhaps they made the togari defconfig based off honami, and corrected that when making the togari_brazil defconfig). It doesn't make any difference for me, disabling them keep the touchscreen (MAX1187) functions normal.
Well, back to the point: even when applying these differences to the ZU DooMKernel, the digital TV doesn't work. The app stays a long time in a black screen, and finally closes (FC). I investigated the kmsg and logcat, but nothing useful.
CONFIG_DVB_CORE is "m" by default. I tried insmod'ing every module in /system/lib/modules, but same result. I temporarily gave up, because I don't watch the crap they broadcast on the open TV here. But yeah, it would be good to have everything working...

I hadn't got around to diff'ing them I just noticed the DVB line and had a quick look at the brazil defconfig.
I guess there is a binary blob that is needed?
For some reason I have to include the clearpad stuff at the moment in the pimped kernel, I should dig to find out why so the kernel is a tad smaller.

Hmm very good insight about the binary blob... It's very possible. I have FTFs for the C6833 and C6843, I'll extract them and compare the file list.
I made it work!! Well, involves some manual steps, but it's a very good progress. I started by comparing the file listing in /system from stock C6833 and C6843 firmwares, and although there is no kernel blob, there ARE some files related to DTV, mostly dynamic libs (.so), some configuration, but most importantly, these two:
Code:
/system/bin/dtvsdserver
/system/bin/dtvserver
So, I insmod'ed every module related to DTV/DVB, and then started these guys... And the TV works! BUT, as soon as I quit the Mobile TV app, the process "dtvserver" is killed with a hangup signal, and opening the app again does not restart it, so I have to manually bring the dtvserver up first (otherwise the same previous issue happens, black screen and finally Mobile TV FC's).
I notice some DTV/DVB modules couldn't be insmod'ed:
Code:
insmod: init_module 'dib3000mc.ko' failed (No such file or directory)
insmod: init_module 'dib7000m.ko' failed (No such file or directory)
insmod: init_module 'dib7000p.ko' failed (No such file or directory)
insmod: init_module 'dib8000.ko' failed (No such file or directory)
insmod: init_module 'dib9000.ko' failed (No such file or directory)
insmod: init_module 'mpq-dmx-hw-plugin.ko' failed (No such file or directory)
insmod: init_module 'tuner-simple.ko' failed (No such file or directory)
But the modules are there, and they are the new ones... I don't get it why they can't be insmod'ed, perhaps something is missing from the kernel config? It could be one of the reasons.
Another thing I've been wondering, is why the DVB modules necessary for the Mobile TV are not loaded automatically, like the wlan module is, for instance. Perhaps a difference in the ramdisk? Something to investigate next.

Congrats on getting that far with the DTV, will make for a more complete device for the c6843 users that want to use custom ROMs
Any differences in udev or init.rc or whatever android uses?
Development using the GPL and GPL'd code
The GPL is a very powerful tool, as are the other OSS licences. One has to know how they are used and can/can't be enforced before publishing any code under these licences or modifying code that that been published under a OSS licence. Using a OSS licence brings with it risks and rewords, often these are one and the same.
When we do anything with Android [Linux] kernels we fall under the bounds of the GPL v2 that it is published under. Any modification to the kernel has to be published under the same licence, and we have to publish the newly modified source in a sate that can recreate the binary that you publish to the public/xda.
I'll leave you with this quote from http://programmers.stackexchange.com
...are you prepared to live by it, and let other people use what you've written, rather than just liking it because of what you can get out of it?

F2FS mount and sysfs options
Now that we have an F2FS-enabled firmware by default, I've been reading about the mount options and sysfs entries available. As many of us know, there are lots of tweaks out there for EXT4, but what about F2FS? Well, here is the official documentation from the Linux kernel:
https://www.kernel.org/doc/Documentation/filesystems/f2fs.txt
As for the mount options, I think only discard could be interesting (but it's questionable, some people say it's better to schedule a regular fstrim call instead). There are also some sysfs tunables which I think can have a noticeable impact in battery life, and performance. Testing them would require a lot of trial and error. I'm pasting them below for those who don't want to go through the full document:
Code:
================================================================================
SYSFS ENTRIES
================================================================================
Information about mounted f2f2 file systems can be found in
/sys/fs/f2fs. Each mounted filesystem will have a directory in
/sys/fs/f2fs based on its device name (i.e., /sys/fs/f2fs/sda).
The files in each per-device directory are shown in table below.
Files in /sys/fs/f2fs/<devname>
(see also Documentation/ABI/testing/sysfs-fs-f2fs)
..............................................................................
File Content
gc_max_sleep_time This tuning parameter controls the maximum sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_min_sleep_time This tuning parameter controls the minimum sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_no_gc_sleep_time This tuning parameter controls the default sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_idle This parameter controls the selection of victim
policy for garbage collection. Setting gc_idle = 0
(default) will disable this option. Setting
gc_idle = 1 will select the Cost Benefit approach
& setting gc_idle = 2 will select the greedy aproach.
reclaim_segments This parameter controls the number of prefree
segments to be reclaimed. If the number of prefree
segments is larger than the number of segments
in the proportion to the percentage over total
volume size, f2fs tries to conduct checkpoint to
reclaim the prefree segments to free segments.
By default, 5% over total # of segments.
max_small_discards This parameter controls the number of discard
commands that consist small blocks less than 2MB.
The candidates to be discarded are cached until
checkpoint is triggered, and issued during the
checkpoint. By default, it is disabled with 0.
ipu_policy This parameter controls the policy of in-place
updates in f2fs. There are five policies:
0: F2FS_IPU_FORCE, 1: F2FS_IPU_SSR,
2: F2FS_IPU_UTIL, 3: F2FS_IPU_SSR_UTIL,
4: F2FS_IPU_DISABLE.
min_ipu_util This parameter controls the threshold to trigger
in-place-updates. The number indicates percentage
of the filesystem utilization, and used by
F2FS_IPU_UTIL and F2FS_IPU_SSR_UTIL policies.
max_victim_search This parameter controls the number of trials to
find a victim segment when conducting SSR and
cleaning operations. The default value is 4096
which covers 8GB block address range.
dir_level This parameter controls the directory level to
support large directory. If a directory has a
number of files, it can reduce the file lookup
latency by increasing this dir_level value.
Otherwise, it needs to decrease this value to
reduce the space overhead. The default value is 0.
ram_thresh This parameter controls the memory footprint used
by free nids and cached nat entries. By default,
10 is set, which indicates 10 MB / 1 GB RAM.

OK, so I edited wlan_hdd_cfg80211.c and changed line 574 to add an explicit cast:
Code:
vendor_event = (struct sk_buff *)cfg80211_vendor_event_alloc(pHddCtx->wiphy,
Then it passes by this point, but stops in following lines with similar errors (not even pasting here). What I noticed from these errors it that CodeAurora's sources seem to be incompatible with Sony's kernel, because for instance, the function cfg80211_vendor_event_alloc is not defined anywhere (ran a grep over all *.c and *.h files in the kernel).
Comparing with a CM11 kernel, this function is also not defined anywhere, but the prima sources are very different, they don't call it. So I thought: let's use CM11's prima sources.
Bingo!
Compiled fine, booted, and with the correspoding firmware in /system/etc/firmware/wlan/prima, WLAN came up normally after boot. :victory:
Now you mentioned something about CM11's prima sources, from what I understood they are not ideal. Is that true? Because there are CM11-based custom kernels which implement intelliplug (dependent on custom WLAN drivers), for instance.
Hope it works for you. In this case, I'll put together a more organized how-to of what I did.

great!
can you just fork my repo and shift to the branch which worked for you, then send pull request? i will investigate on the Z1...
and yes please do send the steps!
well if we get custom compiled WLAN modules properly working on custom compiled kernel for stock ROM then i can have features like intelli-plug, F2FS, AsyncFS and lots more on stock ROMs!

Well I'm still learning my way around git & GitHub, so I think it will be faster if you just reproduce the steps below:
1) Copy Prima WLAN sources from CM11-based kernel:
I copied from SlimRom's kernel source. Put the sources under drivers/staging/prima.
2) Modify related Kconfig and Makefile:
drivers/staging/Kconfig
Code:
131,132d130
< source "drivers/staging/prima/Kconfig"
<
drivers/staging/Makefile
Code:
58,59d57
< obj-$(CONFIG_PRIMA_WLAN) += prima/
< obj-$(CONFIG_PRONTO_WLAN) += prima/
3) Modify defconfig:
I'm pasting every option related to WLAN. The Prima options should appear after a "make menuconfig".
Code:
CONFIG_WIRELESS=y
CONFIG_WIRELESS_EXT=y
CONFIG_WEXT_CORE=y
CONFIG_WEXT_PROC=y
CONFIG_WEXT_SPY=y

4) Include Prima WLAN firmware in kernel ZIP file:
Copy from a CM11-based firmware (I used PAC-Rom). Remember to set permissions as 644.
/system/etc/firmware/wlan/prima
Code:
WCNSS_cfg.dat
WCNSS_qcom_cfg.ini
WCNSS_qcom_wlan_nv.bin
5) Include wlan.ko in kernel ZIP file:
Actually I include every compiled kernel module, because we are using a different toolchain and they may benefit from it too. Remember that /system/lib/module/wlan.ko is a symlink, but in my test the target got updated accordingly.

The branch from your kernel was master_kk-4.4.2. The Prima WLAN sources were, as I mentioned, from SlimRom's kernel, branch kk4.4.
I'm attaching the firmware to this post.

Wow this is very nice! Follows the same line of research I've been doing, but this is more "elegant" and in-depth, especially because of all the benchmarks and other comparisons he has done. I'll try this approach myself on my custom builds.
One thing I noticed is that we may still have to use the "hammer" approach with the find & replace of the "-O" flags in *.mk and Makefiles I've been doing, because some of them have these flags hardcoded (i.e. they don't take the value from core/combo/TARGET_linux-arm.mk or other base files). I'll tip JustArchi in his thread about it.
Hi guys, I posted this in the general android section and have had no answer, maybe some one here might know?
I'm trying to build AOSP using CM 11's device tree for togari/togari_gpe and have hit a brick wall after solving the first few make errors.
I have to errors, that I suspect are the same problem:
The first is if I just build with make I get this error:
Code:
Import includes file: out/target/product/togari/obj/SHARED_LIBRARIES/copybit.msm8974_intermediates/import_includes

compilation terminated.
make: *** [out/target/product/togari/obj/SHARED_LIBRARIES/libqdutils_intermediates/mdp_version.o] Error 1
make: *** Waiting for unfinished jobs....
and if I do make bootimage I get this:
Code:
make: *** No rule to make target `out/target/product/togari/kernel', needed by `out/target/product/togari/boot.img'. Stop.
I suspect that both stem from aosp not finding the kernel source?
kernel source is at ~/dev/aosp/kernel/sony/msm8974/ and I'm building in ~/dev/aosp
I'm also trying to build vanir aosp using the same device tree and kernel and make bootimage completes fine.
Any help would be great
Yo, @DooMLoRD, @blueether @dbolivar
You guys have probably registred that Geohot (iPhone, PS3 jailbreaker) has successfully rooted the Galaxy S5 (and can now claim the $18,000 bounty), but i just read that this one-click root tool should work on any device running a pre-June 3rd kernel, i.e Android 4.4.2. The question is, does it work on the Ultra? I'm aware that it's easy to root an UItra AS LONG as the bootloader is unlocked, but this thing circumvents that part, and roots it. I think.
Are there anyone here still left on 4.4.2 that can try?

I made a thread here. It should work.
http://forum.xda-developers.com/showthread.php?t=2783982
I'm going to show you how to build a custom kernel, and a custom boot.img.
Requirements
A linux OS
Kernel source code from Samsung
Android Image Kitchen (Required for the SEANDROID metadata it appends automatically)
GCC Cross Compilation Toolchain 4.8 (You may just clone the repo with git, or download a zip)
Hypothetical workspace directory on the filesystem: /workspace, now prepare it like this:
/workspace/kernel - this is where the kernel source code will be, this is what we will build. Extract the downloaded Kernel.tar.gz here
/workspace/build - this is the kernel compilation result, populated by the build
/workspace/toolchain - this is the required cross-compilation toolchain you download or check-out from the google link
/workspace/kitchen - Extract Android Image Kitchen here
Click to expand...
Click to collapse
Go to http://opensource.samsung.com/reception.do and search for SM-J415, download one of the results, extract Kernel.tar.gz to /workspace/kernel. I believe SWA stands for South West Asia, and MAE - Middle-east Africa, it doesn't matter which you pick, it is related to radio regulations.
Now overwrite the file /workspace/kernel/build_kernel.sh with:
Code:
#!/bin/bash
# The cross compilation toolchain path
export TOOLCHAIN=$(pwd)/../toolchain/arm-linux-androideabi-4.8
# This is the directory for the compiled kernel
export OUTDIR="O=$(pwd)/../build"
export PATH=$TOOLCHAIN/bin:$PATH
export ARCH=arm
export CROSS_COMPILE=arm-linux-androideabi-
export THREADS=$(nproc --all)
export COMMON_ARGS="-j$THREADS $OUTDIR arch=arm CFLAGS_MODULE=-fno-pic arch=arm"
if [ "$1" == "build" ]; then
make $COMMON_ARGS j4primelte_sea_open_defconfig
make $COMMON_ARGS
elif [ "$1" == "rebuild" ]; then
make $COMMON_ARGS
elif [ "$1" == "clean" ]; then
make $COMMON_ARGS distclean
make $COMMON_ARGS clean
else
echo "./build_kernel.sh build|rebuild|clean"
fi
Building kernel source code
Run the script:
$ cd /workspace/kernel/
edit: /workspace/kernel/arch/arm/configs/j4primelte_sea_open_defconfig
change CONFIG_SECURITY_DEFEX=y to CONFIG_SECURITY_DEFEX=n
$ bash build_kernel.sh build
It should build normally, if it fails there's something wrong with your OS setup. After a long time, you should see the compiled and compressed kernel with the DTP appended at:
/workspace/target/arch/arm/boot/zImage-dtb
The kernel configuration it created from the defconfig files in the kernel source tree is at
/workspace/target/.config
Build a new boot.img
$ cd /workspace/kitchen
$ bash unpackimg.sh /path/to/a/boot/or/recovery.img
Now you will have the unpacked kernel in: /workspace/kitchen/split_img/boot.img-zImage
Delete it
$ rm split_img/boot.img-zImage
Link the built custom kernel there instead
$ ln -s /workspace/target/arch/arm/boot/zImage-dtb /workspace/kitchen/split_img/boot.img-zImage
Now each time you create the boot.img, it will include your custom kernel instead.
Tweak the files and ramdisk as much as you want, and repackage the boot.img
$ bash repackimg.sh
Now you have a boot.img at /workspace/kitchen/image-new.img that is ready to flash to the device. You can unpack custom recoveries the same way as you unpacked boot.img to make them use your custom kernel.
Kernel configurations tried
CONFIG_SECURITY=n - boot loop
CONFIG_SECURITY_SELINUX=n - boot loop
CONFIG_SECURITY_DEFEX=n - works
CONFIG_DM_VERITY=n - works, does not prevent initramfs from using DM-VERITY, you still need some sort of ramdisk hack to disable verification of the next boot phase after initrd.
Often when editing the defconfig files, the same variables are declared in many different files so you might be better off using "sed' to change the variables, example:
$ grep -lr "CONFIG_SECURITY=y" | while read line; do sed -i 's/CONFIG_SECURITY=y/CONFIG_SECURITY=n/g' $line; done
When running "build_kernel.sh build", it will print "configuration written to .config" so verify that the variable was actually changed in the final config /workspace/build/.config

Type "make xconfig" in the kernel directory, and a window will open for configuring the .config file in that same directory.
Search for "Loopback device support" and add a checkmark (not a dot, so that the module is built into the kernel.)

It's telling you the path to the defconfig doesn't exist.

But I have 2 problems :
1- Device is arm and at bulid_kernel.sh tell me to use toolchain arch64 ,
Which I should Use arm or arm64 ,
I confused as cpu is arm64 .
https://www.qualcomm.com/products/snapdragon/processors/425

2- Which command I should write after menuconfig

Or
make -jX .

Just use whichever is in the build script.
You will need to add menuconfig to build_kernel.sh before make or your changes will be lost.
Then run build_kernel.sh

@ashyx ,all is ok .
The error from clang and there is 2 config files .
Fixed and I will test kernel but I have problem when compiling I choose lz4 type ,do U see I should choose another .
Also where is zimage now ,i compiled manually not with build_kernel.sh .
Click to expand...
Click to collapse
You don't need the export arguments which are contradictory anyway, as you have already defined your toolchain and architecture before hand.
Also the boot image does not need to be lz4. The compiler will tell you where the finished zImage is when completed. You should find it in the boot directory of the arm64 directory if you are not using OUT_DIR statements.
kapmino269 said:
Sorry ashyx this is last thing ,
-You told me later that device is arm not arm64 .
In Your twrp thread .
-Also defconfig of device in /arch/arm .
-Arch=arm in build_kernel.sh .
-Gsi system armaonly only work on the device .
-All apps told that device is arm .
I confused ,
Please tell that it is right to use arm64 tool chain .
Or How did U build it ?
By arm64 toolchain or arm toolchain ?
Very Thank U .
Click to expand...
Click to collapse
I was just going by the screen shot you posted. Like I said your commands are contradictory.
You have both arm and arm64 toolchains defined in the same script.
You also have an export statement for arm64 directly under a statement for an arm toolchain.
Not sure why you added both?
As far as I can see the architecture you're compiling for is arm, so you need an arm toolchain.

This is the script I use.
You will need to modify the path to your toolchain.
