OVERVIEW
Bon tout à l'air déja "open bar", toutes les partitions sont en r/w, pratique...l'utilisateur ABD est root... bref rien a faire :)
LEs partitions sont identifiées, je vais dumper les ROM et vous tiens au courant
C'est ma seconde tablet android, je me demande si cette petite tablet a un 'Restore Mode' et quelles sont les combinaisons de touches pour y accéder...
J'ai essayé les trucs évidents mais rien...une idée ?

Voici la procédure des dumps des partitions system et data reussie et quelques hypothèses sur les autres partitions avec tentative de montage

NAND DUMPS

NANDA : /dev/block/nanda (fat16)
# dd if=/dev/block/nanda of=/mnt/extern_sd/nanda.dump

32768+0 records out
16777216 bytes transferred in 3.970 secs (4225998 bytes/sec)
# ./adb pull /mnt/extern_sd/nanda.dump

Comme je ne sais pas ce que c'est que cette partition, un petit coup d'oeil avec un editeur hexa pour voir si je peux la monter...

C'est un systéme de fichier en FAT16, On va donc tester de la monter en vfat...

Salut,

Bon je suis toujours en train d'essayer d'identifier les partitions et surtout d'essayer de comprendre la procédure de boot de la tablette. Je commence a me rendre compte que la tablette basée sur le F20 est très proche des tablettes basées sur le A10 "allwinner". J'ai donc trouvé la procédure pour mettre la tablette en bootloader avec les outils specifiques.

PARTITIONS MAP

Je peux commencer dresser une carte, mais la partition de boot me pose problème, je n'arrive pas à identifier le bootloader. Il y'a des fichiers qui semble inutilisé sur la nanda ce qui ne facilite pas le reverse.

Nand Map (temporaire) :
nanda : BOOT : Partition de boot + noyau linux (la partition est sale)
nandb : UNUSED : Semble non utilisée (certains fichiers de boot y font reference en root=)
nandc : SYSTEM : Montée sur /system
nandd : DATA : Montée sur /data
nande : FS : / (Aussi montée sur /mnt/sdcard)



ALLWINNER

Ce fabrquant fournis entre autre le fameux A10, les architectures sont relativement proche, on trouve un peu d'info sur ce processeur, et surtout il existe un fork "allwinner" officiel du kernel linux pour cette famille.

A10
Image IPB

F20
Image IPB

AllWinner Technologie : http://www.allwinnertech.com

Il existe un outils "LiveSuit" qui permet de flasher la NAND des processeurs allwinner en mode bootloader

Download LiveSuitPack_version_1.09_20111101 (with english language):
http://www.tabletted...TUzLmhvdGxpbms=

http://www.youtube.com/watch?v=oL5KnVH6inQ&feature=youtu.be


RESTORE OU BOOTLOADER ?

Je confirme qu'il n'y a pas de mode "restore" sur cette petite tablette, par contre il est possible de passer le tablette en mode bootloader et grave a l'outils "LiveSuit" de flasher la NAND.
J'ai effectué l'installation (windows only) sur un Win7 (avec les driver usb dédié), la tablette semble être détectée, je n'ai pas encore tester de flasher.

Pour passer la tablette en mode bootloader :
1 - La tablette doit être eteinte
2 - Maintenez appuyé la touche "Volume +"
3 - Brancher le cable USB au PC
4 - Et tout de suite après appuyez 5 fois très vite sur le bouton "power"
5 - La tablette semble rester éteinte, mais Windows détecte un device inconnus, indiquer les pilotes LiveSuit et zooo...
6 - Une fois les bidouilles terminées, sortez votre trombone et faite un hard reset en le glissant dans le trou a coté du bouton "power".

Je cherche donc a bien identifier la mecanique du bootloader avant de flasher quoi que ce soit, je cherche aussi a créer un fichier image unique pour utiliser déja sous LiveSuit avant de reflechir a un update.zip

Salut

J'allais poster pour dire que je venais de recevoir cette petite tablette POLAROID ... !!! en cadeau pour avoir commandé des fournitures de bureau, cool pour moi qui découvre le monde Android :D

Mon 1er réflexe a été de vouloir télécharger quelques Apps que j'ai sur ma Galaxy Tab 10.1 en 3.2 mais ... NON pas comme ça que ça marche :(

Donc ma question est moins technique que celle de bin (bien choisi le pseudo :P )

Comment faire pour télécharger des Apps sans accès à Google Play ?

je rappelle que je suis un vrai de vrai newbie et que je suis en apprentissage, donc je découvre Android 2.3 après 3.2 de ma tab
merci de votre indulgence ^_^


A bientôt

Looping ;)

Salut Looping,

Oops je n'avais pas vu ton post hier...Bienvenu, et cool d'avoir un deuxieme utilisateur de ces petits bidules...
:) je dois commander mes fournitures aussi chez JPG :)...
Si je trouve un gAppMarker.apk je te tiens au courant....
Regarde aussi dans "télécharger" sur la tablet puis clique sur le bouton menu...

Si non, J'ai encore du mal a comprendre la sequence de boot du F20, la partition semble comporter un vieux relicat du A10, je ne sais pas si les fichiers tons véritablement utilisé...
pas de boot.axf... serais ce le app_demo.axf le bootloader ?

Salut, je crée un autre sujet ( http://forum.frandro...te-polaroid-43/ ) sur la tablette pour éviter de "polluer" celui de développement à bin. Je suis dans le même cas que toi.

Et bonne chance bin, je crois que tu es un des seuls à faire des recherches dessus !

Salut,

Après avoir écumé le net sur tous ce qui touche au F20, allwinner, boxchip, socship, etc...Je n'ai pas trouvé de véritable réponse concernant la mécanique de boot du F20, du coup, j'ai commencé a passer la carte électronique au peigne fin et j'ai trouvé un port série (RS232) au niveau TTL.

UN PORT SÉRIE ACCESSIBLE
Dans le répertoire /dev on a bien un device (block) /dev/ttyS0, un petit test de transmission m'a permis de valider que c’était bien un port série.
# cat truc.txt > /dev/ttyS0
Les Niveaux électriques de la tablette et du PC sont différent (Tablette: TTL [0,5V] ; PC: [-12,12V] ), il faut quelques composants entre les deux pour faire cette adaptation. Ne branchez pas la tablette directement au PC dans l'état. Je n'ai pas eu le temps monter un petit max232 pour adapter le signal et voir ce qui sort de ce port.

Le truc intéressant, c'est que immédiatement après l'allumage une trame est émise par la tablette puis ensuite celle ci semble relativement bavarde durant le boot et même après...


ATTENTION : Vous pouvez endommager irrémédiablement vous ou votre matériel et/ou annuler votre garantie avec ce genre de bidouille, vous êtes seul responsable des problèmes que vous pourrez occasionner...

IMPORTANT:
Il faut que capot ferme sans forcer et surtout sans tordre la dalle, si non la tablette démarre mais la dalle tactile ne fonctionne pas, il y'a des composants sur la nappe, il ne doivent pas être compressé, j'ai été obligé d'enlever le scotch bleu que j'avais mis, il est vrai, un peu à l'arrache....

Pas facile de choper une trame avec l'appareil photo...avec une petite vidéo ce sera plus pratique pour faire des hypothèses...

http://youtu.be/eabA3v0XoeY

Voici donc une hypothèse de ce que l'on peut s'attendre à recevoir sur le port série...

0:10 - Allumage, première trame émise immédiatement (Est le prompt du bootloader ?)
0:11 - Affichage logo polaroid
0:13 - Longue trame ~2sec (Est ce noyau linux ?)
0:17 - Courte trame
0:18 - Courte trame
0:23 - Courte trame
0:38 - Affichage logo android
0:54 - Courte trame (Est ce init ?)
0:55 - Courte trame
Etc....

Dès que possible je monte le max232 pour répondre a toutes ces questions, j'éspère surtout avoir des infos sur le bootloader...

Et si quelqu'un qui passe par là, sait a quelle moment le noyau linux est réellement chargée...
Est ce que le chargement ce fait avant ou pendant le splash Android avec la bar de progression ?
(j'ai l'impression que le noyau fini d'etre chargé et est lancé au moment du splash Android, il démarre précisément a 0:38, avant j'éspère que c'est le bootloader qui est bavard...)

Salut,

Après avoir bricolé un petit adaptateur RS232 un peu root, j'ai le plaisir de vous livrer un bootlog complet de du F20.

SETUP
Je n'ai pas de Max233 sous la main (la version 3.3V du Max232) donc j'ai fais ça à l'arrache avec un 2N2222A (en inverseur) une résistance de 2.2K sur la base et une de 1K en rappel sur le collecteur. Mon convertisseur USB/RS232 choppe le transitoire donc 5 V d'alim suffisent...c'est de l'expérimental :P

J’espère que l'analyse de ce log me permettra d'avancer sur la mécanique de boot de ce satané F20 mais on peut déjà imaginé un tas de petite applications d'automatisme ou robotique légères avec Android comme contrôleur pour 40 dollars....

Hi bin,

sorry for not writing francais. I have a similar device which is called (german) Touchlet pmt43-wifi.
It seems to be exactly the same, but i cannot flash it, because the menu key doesn't work.
Could you please give me the nand[a-e] - Images of the 4.3 Android ?

Hallo Matzpx8709,

Thanks a lot for this good information, you get right, it's the same, this going to extend my search.
I dont get the nand[a-e] for 4.3 (ICS) yet, this is that why i play with the bootloader before bricking it, i let you know if i found someting for 4.3. For you key combinaison, did you try the last versions of "LiveSuit" (1.7 at least for F20). Be sur you use the LiveSuit USB driver. (i upload here if needed http://binbones.com/...20_LiveSuit.rar)
1/ Be sur the device is off
2/ Press and keep Vol+
3/ Connect USB (first time he ask to select LiveSuit driver)
4/ Try to press quicly 10 times power
5/ LiveSuite react, you can probably flash with....
An other thanks
Bin

Salut Matzpx8709,

Merci pour l'info, c'est le même modèle.
Je n'ai pas les partion nand[a-e] pour ICS 4.3, c'est pour ca que je fais quelques essais sur le bootloader avant de bricker le device. Pour la combinaison de touche, vérifis que LiveSuit est bien a jour (1.7 pour F20) et assure toi que le driver USB utiisé est bien le driver LiveSuit
(je l'ai uploadé ici si besoin http://www.binbones....20_LiveSuit.rar)
1/ Le device doit être eteint
2/ Presser et laisser appuyé Vol+
3/ Connect USB (La première fois vous devez intaller driver LiveSuit)
4/ Presser power 10 fois rapidement
5/ LiveSuite reagit, tu pourra peut etre flasher....
Encore merci

Hello bin,

many thanks for your driver, i will try that.

what i found out so far is, that you can have many sections in the boot.ini in the nanda-Partition:
mine looks as follows:

[
system]
start_os_name = linux
timeout	   = 5
display_device= 0

[linux]

[matz]
with this section matz, you can have a directory /boot/matz parallel to /boot/linux,

In this section matz, you have to have a "matz.ini" instead of a "linux.ini".
When you have, for example a [polaroid] section, you have a polaroid.ini

when you press power for 2 secs, then release power
then press vol+ 1 time, you select boot section matz,,
by pressing again vol+ 1 time, you select boot section linux.
by pressing shortly again polwer, you start the selected boot section.



by this way, you dont have to brick something. (the youda and all other dirs in linux arent needed, there are only alternative logos for boot in it. mine in section matz is internet.

i am reporting my experiences here again when i am further.
many thanks until here.

------------------------------

Hello bin again,

i tried your package on my tablet.
with your description of the keys, it worked now, that the driver installed.
But flashing isn't possible, because of an error, which is undeclared :-))

it is a messagebox with caption lifesuit and symbol "!" and message "" (blank)

------------------

when i am using livesuite 1.09 (from above link),
i am getting this message readable and it says "no device needs upgrade".

Good information sir, can you tell me if you get boot.axf or app_demo.axf as stage 2 bootloader on nanda partition ?

Traduction : Matzpx8709 nous montre la nanda du pmt43, je lui demande quel fichier de bootloader est present sur la nanda


when you press power for 2 secs, then release power
then press vol+ 1 time, you select boot section matz,,
by pressing again vol+ 1 time, you select boot section linux.
by pressing shortly again polwer, you start the selected boot section.

Gooooood.....many thanks for this information, i heard about this but this indicate you get a real "boot.axf" not strange "app_demo.afx" as bootloader, did you confirm ?

Traduction : La procédure indiqué par Matzpx8709 permet de sélection un noyau au boot, je lui demande donc si il possède un boot.axf ou l'etrange app_demo.axf comme bootloader

i tried your package on my tablet.
with your description of the keys, it worked now, that the driver installed.

Good news

Traduction: La version de livesuit semble fonctionner

i am getting this message readable and it says "no device needs upgrade".

Wich firmware did you try ? this probably because it's not the good rom/device i read sometime.

Traduction: Son premier essais de flashage a echoué avec le message "Aucun periphérique n'a besoin d'être mis à jour", je lui demande avec quelle rom il a essayé

Many thanks matzpx8709 for you return and informations
I let you know too...

Hi bin,

it is not boot.axf, it is app_demo.axf.
if you make (with linux) a strings app_demo.axf, you can see some keywords for the boot.ini.

and i tried both firwares, the one for android 4.0.3 and also for android 2.3 (Version 2.5).
as far as i saw in your tree of the nand, it is exactly identical.

also the `uname -a` is exactly the same.

another hint: i copied init to matz, hexedited the string "init.rc" to "matz.rc" and could experiment with it.
i tried to boot from sdcard, but this seems not to be working.
i tried to remount root on sdcard shortly after boot, but it seems that udev has to be run for creating the dev entries for sdcard (dev/mmcblk0p1)

if you could copy the nands from your android 2.3, i could investigate possible differences.
especially your nanda is of greater interest for me.

thank you so far ..
please come back ...

hi bin, hi all,

i can boot the polaroid kernel.
it differs in size 4 bytes and is not binary equal.

the serial number in my kernel is 59 while in polaroid kernel it is 22, also the dates differ.

my kernel version is:
Linux version 2.6.36.4 (M10-Android-Team@Linux) (gcc version 4.3.3 (Sourcery G++ Lite 2009q1-203) ) #59 Thu Nov 17 16:49:13 CST 2011

the polaroid kernel isnt able to boot from sdcard also.

because my device is registering also on linux with Bus 007 Device 002: ID 1f3a:efe8, i
will try lifesuite on another machine with a different windows (mine was win7 starter on a netbook).

hi all, hi bin,

its sad, i am not able to update to 4.0.3 with my device. neither the 1.07 nor the 1.09 neither in win7 nor in win xp does work.
but the other image with the android 2.3 is also not flashable on my device.

does someone know, who vendor id 1f3a is ?

in win xp i always get the message "no device available".

my last idea is, if i would get your roms of the 4.0.3, i could write them raw onto the device, but this is very dangerous, because they are mounted. (possibly remount ro, don't know if this works).

the filesizes of the drivers/bootprogram in the boot partition (nanda) are the same as in my "touchlet pmt43-wifi".

Hello Matzpx,

I think we break the "forum moderation rules" with english language, i 'm going to ask moderator for derogation but i think we may go to an english forum or wiki if you want...i follow you and stay here for french return....

its sad,...

It's a bad day for me too, i brick my own app_demo.afx say : "No OS to Boot !" i see on RS232 :)
I try to create a bootable mmc, not successfully but interested results
1 - I can show different number int app_demo.axf boot with keys combinaisons
2 - i think my card begin to boot and arm crash immediatly (opcode/sramaddr must me not valid)
(i need to investigate more)

... i am not able to update to 4.0.3 with my device. neither the 1.07 nor the 1.09 neither in win7 nor in win xp does work.
but the other image with the android 2.3 is also not flashable on my device.
...
in win xp i always get the message "no device available".

I try different ROM with same results XP&7, but i think this is a ROM/device "ID" probleme, what do you think about ?

does someone know, who vendor id 1f3a is ?

i think this is a AllWinner corp id or the "usb chip subset" supplier...i dont know

my last idea is, if i would get your roms of the 4.0.3, i could write them raw onto the device, but this is very dangerous, because they are mounted. (possibly remount ro, don't know if this works).

hum...I think the bootable mmc is a more safer way you always can recover...

the filesizes of the drivers/bootprogram in the boot partition (nanda) are the same as in my "touchlet pmt43-wifi".

Ok, can you publish your nanda ?


SYSRQ EMBEDDED
If you got a serial port, you can send a command to linux kernel with sysrq
(Change log level, show-registers, etc...) here is the help show by kernel
[   48.720000] SysRq : HELP : loglevel(0-9) reBoot Crash terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) thaw-filesystems(J) saK show-memory-usage(M) nice-all-RT-tasks(N) powerOff show-registers(P) show-all-timers(Q) unRaw Sync show-task-states(T) Unmount show-blocked-tasks(W)

BOOTABLE F20 MMC : FIRST TRY
I try to create a simple binboot.S with theoricaly send "H" to UART0.
I use the A10 register map (from uboot and leechee), this will probably the probleme, i will disam the app_demo.afx to confirm the UART base addr.

1 - Fake bootloader
start:
	ldr 	r0, =uartaddr
	mov 	r1, #72
	strb 	r1, [r0]


done: 	b 	done

uartaddr:
	.word 0x01c28000

I build with
arm-none-eabi-as binboot.S -o  binboot.o

Remap with, (get this baseaddr from app_demo.afx disasm but it can be an other probleme)
arm-none-eabi-ld -Ttext=0x82800000 -o binboot.elf binboot.o

I got only executable code
arm-none-eabi-objcopy -O binary binboot.elf binboot.bin

2 - Create a All Winner mmc special binary
I found this https://github.com/hipboi/mksunxiboot
(and just discover https://github.com/amery/mksunxiboot)
This as the allwinner mmc header, i see the "jump address" in header, i need to investigate here
mksunxiboot binboot.bin binboot-mmc.bin

3 - Put it into mmc
sudo dd if=binboot-mmc.bin of=/dev/sdb bs=1024 seek=8
sync

4 - Result
A: When i put a standard mmc, app_demo.axf start and say "No OS found !" on serial port
B: When i put the custom mmc, dont see anything, app_demo.afx is not started, nothing on serial port
I thin F20 try to start by uggly code and crash and/or reboot indefinetly...sometime when i unplug the mmc, it restart immediatly and start app_demo.afx...
I need to enforce my ugly bootloader with good mapping and good serial uart register and be sure allwinner header jump is ok

I try to boot directly the app_demo.afx on cf, but nothing append, i think F20 search a Boot0 on mmc not a Boot1(app_demo.afx)

hi bin,

if we are breaking rules of this board in writing english, lets go to an english forum. but maybe moderator is friendly.
my french is only two years in school, so i cannot write in french.

mai je aime la france. :-))))

i dont think, booting directly from mmc is possible.
eventually the way could be u-boot, wich can load kernel images and have a root on mmc.
have a look at github.com, there is a spain programmer called Alejandro Amery(amery), which is working on allwinner a10:
https://github.com/amery
there is also a kernel which contains allwinner sun3i (F20) code, but it isn't compilable, because of missing dma.c-routines.
he also worked on u-boot and sun4i (a10).

maybe that could help.
