Anyone know which NFC chip the Xperia Tablet Z uses? I've found references to an NXP 44701, but can't find a data sheet or anything else on that part. I also find it curious that many of the NXP parts begin with letters, not numbers.
I'd like to know what the chip's part number is, and how it is interfaced to the main CPU. It does not appear to be USB. Anyone know?
Thanks!
I wonder that as well.. nobody knows?
Hi,
the number 44701 clearly indicates a PN544. Where 44 is the short code for PN544 and 701 is chip revision information.
Regarding its connection to the application processor: The chip should support HSU (High Speed UART), SPI and I2C. For NFC chips on Android this is typically I2C due to the existing kernel drivers (cf. https://github.com/sonyxperiadev/kernel/blob/yuga-aosp/drivers/nfc/ for Xperia kernel).
br,
Michael
I have here a phone I am planning on using as my pilot project into android development and need some help determining some things.
I know that as a beginner this is not going to be easy but I hope working my way through this will enable me to learn a lot in the process. I recently got hold of a Samsung clone powered by a Mediatek mt6572 processor. I chose this because 1) the phone is cheap 2) I view Mediatek processors as virtually "un-brickable" and 3) it will be challenging if not impossible. The problem I am facing now is that I got it used with a broken screen and digitizer. Having replaced both I am now faced with my first challenge getting the kernel to properly support the replacements.
The touchpad is not recognized at all (or at least it doesn't respond) and the image on the screen seems to be inverted along the y axis. I am in the process of gathering information and would like to know is there anyway to discern the relevant driver for the touchpad while only knowing the controller IC?
I have been searching online trying to find a product that it was used in but so far the only thing I have been able to find is the datasheet.
tl;dr; I need help finding the driver that would support the controller IC for the touch-pad on my phone. The IC is made by Chipone and is in the INC830x series. INC8305M to be exact.
Thanks for your help.
Hi guys,
I have a bunch of these tablets available and they're quite useful - the only hitch is that the company selling them has no idea what they are or what they're capable of. So what I'm trying to do is identify exactly what tablet this is so that I can figure out what roms might work etc.
It's based on the RK3188 chipset so that's fine as rockchip are pretty decent for firmware etc - I just want to make sure I get the right stuff.
I can adb into it and managed to dump all the info for it: Wpq0qfby (pastebin)
The homepage_base url points to Aurus Electronics but the only 10" device there isn't quite the same - the camera is different as are the specs and the button layout.
It most closely resembles this: PIPO-M9-Tablet-Resolution-Android on amazon but again, although it has the metallic back plate, the button layout and so on are different.
It is most likely a China based knock off. As for roms you will be hard pressed as there is no kernel source for these devices and most of the time they don't even have the hardware they claim they do.
I have bought a dongle and discovered it does not have the usual RK SoC , instead it has an Allwinner A10. The pcb is red, it has the SoC, flash, sram, some voltage regulators and a push button and a led. Does anyone have any idea where to get firmware roms for this dongle? The stock firmware is very bad. Dlna barely works. Miracast disconnects immediately after connection.
@an31415 people would need the name and model number to stand a chance of helping you.
I think the best you could hope for is firmware from another identical device sold under a different brand name.
if you were able to try this you'd still need to have the original firmware on hand in case it didn't work.

Thanks @3mel for your reply. The product box says "HDMI Dongle Wifi Display Receiver" and on the dongle it is written "Anycast". This is one of the many clones you can by on Aliepxress. I was hoping it's one with an RK cpu, but after cracking it open I found out it has an Allwinner A10 cpu. I searched high and low on internet to find and alternative firmware for it because the current one is crap. I'll try to attach some pictures here of the PCB, maybe somebody can identify it and point me in the right direction.
But how do I attach picture? Can junior members do it ?
More info: the dongle PCB is red and has a label, SP-X11-V2.0, and the name of the Wifi access point it creates is SP-xxxxxx, where the Xs are random hex digits.
The Wifi addon pcb is green and has no markings. The wifi chip is a well known Realtek that is found in all other similar products.
if you inbox me the AliExpress link I will post it here for you, that's probably the best way for anyone to identify it.

I received the variant in the colorful box(not the blue ones) and it does not say M2 nor M4 on the box. The product description says it has an AM8252 cpu, but it's not true. I guess the only way to id it is to post pictures of the pcb.

the chips aren't the same as yours but does the board look similar ?
being honest I wouldn't get your hopes up, it's a cheap clone / copy of a chromecast. it's not going to be supported that well, they've already sold you something that doesn't match their product description. take it for what it is and learn that you get what you pay for... sorry.
The board is not similar, it has different ICs, different layout, different color. But the plastic enclosure is identical, except for the venting holes on the back, which are bigger on mine. This case copies the Chromecast (first generation), so people expect it to be a Chromecast clone. It isn't, but it does serve a similar purpose
The date on the PCB is 2019.10.10, fairly recent. I expect a new wave of clones have hit the market, disguised as already established products, but based on a different SoC. The only problem is their firmware is even less stable than the old ones, so I guess other people, not just me, are looking for solutions.
some of those people looking need to be devs.
Yup. Or anybody with a similar but not identical A10 based board. Maybe we can spot different fw versions in the wild
A small update if anybody is interested. I've connected the board via usb to my laptop (running linux mint). Doing this while keeping the button pressed will put the board's bootloader in some sort of firmware update mode. Running lsusb will show it as an usb device : "Bus 001 Device 066: ID 1f3a:efe8 Onda (unverified) V972 tablet in flashing mode". Of course this is not an Onda tablet, but it certainly has an identical SoC, thus the misidentification of the usb device.
Googling for this string I randomly found out there are some people called the sunxi community that strive to create a linux kernel and toolchain for these Allwinner devices, and they have done it quite successfully.
There are many custom firmwares for tablets, tv boxes and mini PCs that are based on the allwinner SoC. It seems this miracast hdmi device is just a trimmed down mini PC. It certainly runs pure linux, no Android, because its ram and flash are much smaller than what I found in the specs of any android devices.
So the question is: does any body have any knowledge of the existence of such a linux based firmware for this miracast board ? I'll go ask the sunxi people also.
Hello all,
I am looking for alternatives for my project which used to use the A95X F1 ATV (s905w) as this seems to be no longer produced. TX9S (s912) seems to be a reasonable replacement for now but no idea how long stock will last.
The requirements:
Amlogic CPU, why I'm posting here S905W and beyond.
64bit support.
2GB RAM minimum
8GB Storage minimum
Ethernet port, 10/100 is fine.
Flashable storage, via USB prefered.
HDMI output is useful but not needed.
Barrel connector is useful, power requirements under 2.4A for USB hubs.
I've done research on a board and come up with XPI-S905X by Genitech is a $35 board with pretty much everything I need but with extra's that push it up in price. With open fireware its a cool little board but price for scale in the 10's of boards is required.
If you guys know of any specific options I can't find, ideally higher on the stack then s905w due to supply please provide some info!
What is your project I am still not sure...are you looking for suitable rom?

I am looking for suitable hardware. ROM can come later. Specs as described in main post.

Would be really helpful to know what your project is. Some sort of server?
Your link shows just a board. So basically you can buy any Android box, open the box and throw it away and just keep the board. This will probably be even cheaper.
Your specs are also very low. You can easily find a box with that specs for less than $20

I've looked at a few boxes but the A95X F1 and TX9S seem to be lacking production, finding new ones which can possibly future proof for a reasonable price is hard.
Has to be Amlogic after all, and x96 mini's sometimes don't seem to flash from testing.
