Porting Andoid on A1200 MING

[sabrod]

Maybe you are too hurry
I never saw failed rqsn , but that's maybe not important as you found a workaround.
Maybe wait some few second (like 15sec) after you see USB ready.

I never saw genblob go back to usb ready after sending a zimage too.

I did have to unplug plug sometimes (especially on ubuntu!?) but i was after the kernel booted . ( i setted the rootdelay= to 15 or more for the phone to find the nfsroot, too) .

The pxa-bug isn't important as you have genblob, it should works... (well, in svn the 2.6.25 branches have an old driver that didn't needed this to work. Maybe 2.6-arm have it too, but i'm not sure.).

Hmm, now I'm having a different problem. Holding down Vol+ doesn't enter USB mode any more -- instead, gen_blob gives me:

Cannot load kernel from:
/boot/default

I rebooted to check and make sure I hadn't broken my Vol+ button -- it's fine

Does it matter what mach id I use for gen_blob?

[sabrod]

Yes it does matter, sir.
As root or sudoing

./bootusb genblob 0

0 is genblob machid .
It sounds like you press vol+ key too late.
You need to hold the key, send this command, then release a short instant after
( as bootusb tells you "boot: ok" or so. )

./bootusb genblob 0

I think I was releasing Vol+ before genblob was ready. It's working now.

Using machid == 0 doesn't seem to help. It's still stuck at "USB ready."

Is there a way to turn on extra debugging information?

[sabrod]

Sure.
But afaik bootusb is already quite verbose... (Recent if not last addons) You might want to look at its code...
see http://wiki.openezx.org/Getting_Started for all downloads addresses and handy pre written svn's commands.
I never saw those tools (bootusb and genblob) fail at their tasks, I don't what to tell you except to try this kernel, known to work:
http://people.openezx.org/gmzhuo/zImage-20081206
If you don't have that loop returning to genblob in usb mode, then something is wrong with your kernel, sources...

note that i never compiled genblob, and i beleve it's not easy, and the code might be a little tricky.
But machid is 0 for genblob, and nothing else will work.

[cout]

I don't know why booting the kernel over USB fails, but I gave up trying. It's easy enough to scp a kernel, even if slightly more inconvenient.

I put /boot on the MMC card and set up menu.lst. gen_blob reads the menu and boots the kernel just fine (except the telnet connection to 192.168.1.2 is non-responsive). I still get the error about "Cannot enable port 3", but I think it's okay now, since I am able to mount the root filesystem.

I will try later with a different rootfs. At least the kernel boots now.

[sabrod]

Good news! CONGRATS!!
just curious:
Did Gmzhuo's kernel made genblob's "usb ready loops" ?
0_0
eabi optimized rootfs should be what you need...
Is there rootfs sources availables?

[cout]

I'm able to boot the Angstrom Openmoko rootfs with the android-patched kernel and get a gui up (I tried one of wyrm's kernels, but I guess it doesn't have CONFIG_ROOT_NFS?). The openmoko rootfs automatically starts /sbin/init, so no need for the telnet business.

Androidezx's rootfs does start telnetd (I can connect, but never get a login prompt). No luck yet getting init and /system/bin/runtime to start automatically (I'm not even sure yet if /etc/init.d/rcS is running -- blackbox is a mysterious black box to me ).

[sabrod]

Right I don't see nfsroot support on latest wyrm's zImage , but i guess some of his compilations does have ??
I've heard that wyrm's lasts kernels were also compiled with a lot of debug options on mux driver that cause them not to work well , but maybe it's only fables ... (you should be able to read Wyrm's kernels config on a file named buildlog-XXX next to the kernels themself EDITED: there is now alos a config-XXX file (his wyrm/image/* folders on http://people.openezx.org/wyrm/image).
That is why i pointed you to gmzhuo's http://people.openezx.org/gmzhuo account.
It's the last recent kernel uploaded that i've heard positive report.

hi, all:
With the guide of "Porting Android to A1200", i run ‘./init’ execute after telnet into phone.
After i see Android string on A1200'LCD, i see "can't access tty.job control turned off" also.
To solve it, i try :
1)remove /dev/console and /dev/ttyS0 ;
2)#mknod –m 666 ttyS0 c 4 64
#ln –s ttyS0 console
3)Add the below item to /etc/inittab
console::sysinit:-/etc/rcS
ttyS0::respawn:-/bin/sh

After that i get: No such directory of /etc/rcS. i am sure there is console and ttyS0 device under /dev dirctory, but there is no "rcS" under /etc.
How can i get a the file rcS??
How to solve the issue of "can't access tty.job control turned off"? ?
