Android for i.MX51-BBG

RashmiRamanna — Thu, 29 Oct 2020 09:09:11 GMT

Hi all,

I am porting android to i.MX51 BBG platform.

I followed i.MX_Android_R10.4_User_Guide and built the android.

But Android Gui is not starting on dvi monitor.

I am sure I am giving correct bootargs.

The log is as below

from_bootup.cap

Later I built the Android by using below command

make PRODUCT-imx51_BBG-eng

I am able to get Android GUI but all applications failing.
The log file is attached as eng.cap

Please can anyone tell me how can I fix it.
eng.cap

Original Attachment has been moved to: 166-from_bootup.cap

I think some permission issue is there thats why it is rebooting with below message.

"AndroidRuntime START com.android.internal.os.ZygoteInit"

Try to give rw permission in init.rc as below and check.

on post-fs
# once everything is setup, no need to modify /
mount rootfs rootfs / rw remount

or somewhere else permission is missing.

share your init.rc file once.

i think some permission issue or some mounting partition issue is there as per your eng.cap log.

Tell me some of the below questions.

(1)You are doing it for froyo or gingerbread?

(2)you are booting through mmc or NFS?

(3)Are you getting properly android boot logo animation while booting the board.

I am using gingerbread. Booting through MMC. Yes I am getting android boot logo.

After that all android applications are failing......

Have you tried both the below bootargs?

console=ttymxc0 init=/init androidboot.console=ttymxc0 di1_primary pmem=32M,64M fbmem=5M gpu_memory=32M calibration

console=ttymxc0 init=/init androidboot.console=ttymxc0 di1_primary video=mxcdi1fb:RGB565,bpp=32 pmem=32M,64M fbmem=10M gpu_memory=32M calibration

is it booting on normal LCD of EVK instead of DVI monitor.

Re: Android for i.MX51-BBG

RashmiRamanna — Thu, 24 May 2012 06:09:17 GMT

Ok,i think some memory issue might be there,i am not sure much.

Is it customized board or imx EVK from freescale.

Re: Android for i.MX51-BBG

RashmiRamanna — Thu, 24 May 2012 06:50:48 GMT

Its same as imx evk freescale board.

Re: Android for i.MX51-BBG

nit123 — Thu, 24 May 2012 10:56:07 GMT

if it is not a standard EVK of IMX51 from freescale than you may need to change the memory related boot args.

Just try to increase one by one memory related bootargs values like for pmem,fbmem,gpu_memory.

Re: Android for i.MX51-BBG

RashmiRamanna — Thu, 24 May 2012 11:49:35 GMT

Sorry Its the standard board I received from customer.

Once the Android GUI starts on DVI monitor I see android.process.media failing...

After some minutes system is going to suspend state. How to solve this?

Thanx
