[DEV] unofficial CyanogenMod 9/ClockworkMod Recovery 5 for Amlogic AML8726-M tablets

---

this is a work-in-progress development project for porting CyanogenMod 9 (ICS/4.0.4) and ClockworkMod Recovery 5 to Amlogic AML8726-M tablets.

this is not perfect at all. and I'm very busy. progress will be very very slow. I may not be able to answer your question/request. if you have some idea for improvement, please do it freely.

there is no support from any makers/vendors. you must agree all risks by installing non-supported files, it may brick your tablet, and you may lose official support/warranty.

* YOU MUST READ CAREFULLY POST#1, #2, AND #3!
* DO NOT USE IF YOUR TABLET IS NOT LISTED BELOW. IT WILL BRICK YOUR TABLET!

* How to boot ClockworkMod Recovery 5
1. download recovery.zip and unzip it
2. put aml_autoscript and uImage_cwm on root of SD card
3. insert SD card
4. power on

you can flash uImage_cwm directly into recovery partition. then, you can boot recovery with VOL+ + POWER.
ClockworkMod Recovery 5 can't install official update.zip. if you want to reinstall official ROM, use uImage_recovery in official ROM.

* How to control ClockworkMod Recovery 5
for ainol NOVO8 Advanced
VOL-/jogball down: down, VOL+/jogball up: up, POWER/jogball push: select, SEARCH/BACK: back

* How to install CyanogenMod 9
1. download update.zip and put it on internal NAND flash or SD card (don't unzip it)
2. reboot recovery
3. install update.zip
4. wipe data/factory reset *1
5. reboot

*1 only if you are upgrading from non-CM9 ROM (CM9 1st install)

* issues

- mic input(audio record) doesn't work.
- accelerometer orientation on Digma iDx7 is wrong. please disable it for now.
- scaling and rotating are not worked for hardware accelerated video. video is always displayed as fullscreen and landscape. please use media player which has fullscreen mode (no UI parts).
- to use USB mass storage mode, /sdcard needs to be mounted. i.e. SD card need to be inserted, or, internal NAND flash need to be mounted on /sdcard (by Settings -> Storage -> Storage configuration -> Use internal storage).
- TS calibration is missing. resistive touch screen will not work.

* random notes

- external SD card and internal NAND flash
on CWM, external SD card is mounted on /sdcard. internal NAND flash is mounted on /emmc and referred as "internal SD card".
on CM9, external SD card is mounted on /mnt/sdcard. internal NAND flash is mounted on /mnt/nand.

- ubifs
no ubifs support for now. which is better, yaffs2 or ubifs?
ubifs should be supported if clockworkdmod is used as backup tool for official rom.

- rootfs
currently ramdisk in kernel is used as rootfs. modifying kernel by hand is not so smart.
should try to make initrd separately and pass it via bootm 2nd arg.

- reboot
reboot doesn't work. if power is connected, reboot will work, but power off also act as reboot
reboot recovery/bootloader doesn't work at all. use VOL+ while power on.

- memsicd
is running to use accelerometer (and magnetic field sensor). it also tweak axes by ro.sf.hwrotation and ro.sf.gsensorposition.

- magnetic field sensor
is detected but not worked/not existed. magnetic field aware apps may not work correctly.

hello
works great.
You are really great.
your work with the de novo 8 will be finally a good tablet.
sorry I do not speak English
good luck

Thank you very much from France for your work !!!

I will try this version as soon as possible.

Bye.

First of all: Thank you! It looks great! ;

But, the "- no ubifs support" means I can't mount sd-card or connect internal memory to pc?
I tried, but it not works...

Thanks again!

thank you confirming "not work" things.
for ubifs, please learn about it. this project/thread is for developers.

I can't promise my CM7 port will be good for you. I'll do what I can do, but I can't do what you want.

thank you for your cooperation!

from my personal experience, probably some non-dev people will start to complain "XXX is not working! I need it! please support it asap!". and, 1 month after, "XXX is still not working! terrible! tell me current status of your work!".


this is development project. my files are just for dev people, and non-dev people who know dev work is really difficult or need a lot of time.
my git repo are pushed to github. anyone who can build android/cyanogenmod can build my CM7 for novo8 with it. (how to build is around here and there. don't ask here)

about me(currently only 1 dev here), I'll work for this project only on my free time. I don't have enough time as usual. nothing may be changed within a month. don't ask ETA even if I say "I'll do it soon".
as a fact, on my another project, some people waited some months to get working accelerometer.

test report is always welcome from everyone. but don't expect that issues/missing featues will be fixed if you can't fix yourself without effort.
if you don't like my CM7, please use another one. I never say my CM7 is best, I don't force people to use my CM7.

I'm looking ZT-280 gingerbread (it seems CM) rom. I think something can be used for us. e.g. they have latest mali modules

there is also Gadmei T720 (probably froyo) rom posted on www.chinadigitalcomm.com. I'll check it too.

if you know another rom for other AML8726-M based tablets, please tell me.
