Android FroYo on OMAP35x boot but no display

NuriaPazos

Hello everyone !

I have trouble with Android FroYo on OMAP35x.

The system boot but there is no display except the boot logo despite that I can execute command via distant COM terminal.

There are my spec's :

I use TI_Android_FroYo_DevKit-V2.2 with source compiling / pre-built image and "Out of the box demo" each time I've got the same problem

My device is a TI OMAP35x Evaluation Module Rev. C

bootarg :

setenv bootargs 'console=ttyS0,115200n8 androidboot.console=ttyS0 nfsroot=157.26.100.41:/srv/nfs,nolock mem=128M root=/dev/nfs rw rootfstype=ext3 rootdelay=1 init=/init ip=dhcp mpurate=720 omap_vout.vid1_static_vrfb_alloc=y'

error :

Warning: unable to open an initial console.
# warning: `zygote' uses 32-bit capabilities (legacy support in use)
request_suspend_state: wakeup (3->0) at 41824829105 (2000-01-01 00:00:39.854675295 UTC)

I joint the catlog, the startup boot message and the dmesg output message if that can help

1614.catlog.txt

1602.boot_msg.txt

6786.dmesg.txt

Any help appreciated !

Thanks

Hi,

1.Could you add following to your boot arguments

vram=8M omapfb.vram=0:8M

2. If did not work, kindly boot the target without sgx first.

Just comment

service pvr /system/bin/sgx/rc.pvr start - line in init.rc file

Hi satish,

Thanks for your answer !

I try to add the argument to bootarg but no change...

And no change either with the comment, but i forget to say that i try to comment that line before.

If i uncomment that line i'v got a different error :

Warning: unable to open an initial console.

Is that the problem ?

Thanks !

Hi NuriaPazos,

1. Its good sign!!!

Could you recompile sgx again with the kernel r u using ?

"10201 means OMAPES=3.x and 10003 means OMAPES=2.x",

could you compile your source with correct argument and try out ?

Hi Satish,

Thank you for your answer !

Then I compile SGX with OMAPES=2.x param but still no display except the Android logo but I also have a new error :

if "service pvr /system/bin/sgx/rc.pvr start" is uncomment

It's ok !

I solve my problem !

I compile my SGX with a wrong toolchain (an android toolchain arm-linux-androideabi-)

Then i compile SGX with a CodeSourcery toolchain (arm-none-linux-gnueabi) and it's work !!

I didn't check everything but at least a have a display ;-)

Thanks Satish for your help !
