Hi,

long time not been here... I did not finish anything new, just wanted you to know that latest version of published firmwares for Visson devices can be now found on my website under downloads section.

Cheers

Glad to have you back Stane. It's a pleasure to test for any new rom from you.

Vendor specs says 512MB but android just see 1 of the Ram chips,
maybe the other one is used by mali 400 gpu ?
Also says Android 2.3 but it runs on 2.2.1, cant find compatible upgrade of other M1 board anywhere, device roots fine with z4root apk.

Dumped mtdblocks to sdcard with dd and also copied config files from /system using adb remote shell for backup.

After carefully read of entire thread here and a similar one on DX
Firmware upgrade? [Update: Download Link here]

Way to recover SPI data without Jtag or external programmer.
==============================================
Warning, we are going to use uboot HUSH cmd parser,
this is a very powerful shell missuses will totally break your box ... use with caution!
Your system wont boot cause data in your SPI flash (macronix) is corrupted, also this problem prevent recovery switch to be read from uboot or sdcard to be read.
Some people are doing short between SPI flash pins, do not do that!!
making short between Serial Out Data (pin 2) and ground could lead your chip dead!!
Please better if you lift pin 1 ( Chip Select ) from board and put toggle switch between solder pad and pin (CS On/Off).
This way you boot with chip disabled and enable just to detect erase and flash.
Note: Use Short cables or noise will be catch !!
You will use a USB2TTL (3v3) console cable (GSM datacable) and terminal sw
baudrate 115200,8,N,1.
Also you will need a binary img with SPI contents, on my system I get one from inside update.zip you can use 2 type of files "uImage_recovery" or "SPI.img" need to be less than 4MB to fit flash.Put file inside a clean SD card formated in FAT32

Steps
====
1) Open CS switch (internal pullup will disable flash and put I/O in Hi Z).
2) Conect TTL console port to terminal program
3) Power on box ( in my case I need SD card inserted to boot )
4) Press any key to interrupt normal boot:

0x0001e4f1
0x00000fff

5) Close CS switch to enable SPI flash
6) Detect SPI at uBoot HUSH prompt (note 1):

8726M_DVBC# [B][I]sf probe 2[/I][/B]
SF: Got idcode c2 20 16
SF: Detected M25X32 with sector size 4096, total 4194304 bytes

7)Detect SD at uBoot HUSH prompt (note 2):

8) Load FAT partition 0 (note 3):

8726M_DVBC#[B][I] fatinfo mmc 0[/I][/B]

9) Load file to ram (note 4):

8726M_DVBC# [B][I]fatload mmc 0 0x80000000 uImage_recovery[/I][/B]
4194304 bytes read: OK

10) erase and write loaded image to SPI flash (note 5):

8726M_DVBC#[B][I] sf erase 0[/I][/B]
4194304 bytes erased OK
8726M_DVBC# [B][I]sf write 0x80000000 0 0x400000[/I][/B]
4194304 bytes write OK

11) reset box

Documentation
--------------
(note 1)
sf - SPI flash sub-system
Usage:
sf probe [bus:]cs [hz] [mode] - init flash device on given SPI bus and chip select
sf read addr offset len - read `len' bytes starting at `offset' to memory at `addr'
sf write addr offset len - write `len' bytes from memory at `addr' to flash at `offset'
sf erase offset len - erase `len' bytes from `offset'

In my box SF device is 2 in some MX boards is 0
(note 2)
mmcinfo - mmcinfo <dev num>-- display MMC info of device number stated ex.> mmcinfo 0

(note 3)
fatinfo - <dev num> <partition> print information about filesystem ex.> fatinfo mmc 0

(note 4)
fatload - <dev><offset><$loadaddr><image.file> load binary file from a dos filesystem to <$loadaddr> in ram. 0x80000000 is beginning of ram on my board.

(note 5)
sf erase - <offset><len> if no len specified all chip will be erased
sf write - <$loadaddr><offset><len> len must be filesize in hex with 0x prefix ex.> 0x400000 to fill full 4MB flash.

Optional: you can check your recovery image after step 9 prior to burn in flash with this cmd:

8726M_DVBC#[I][B]bootm 0x80000000[/B][/I]

Update:

Seems device has 256MB after all ... nanya specs:
DDR2 1066 1Gb 64Mbx16 so ... 128MB each chip
x2 = Total 2Gb or 256MB ... difficult to run other than froyo builds
