Can not see android boot image and boot animation logo and not menu

[Chee Huey Pun]

Hi All,

I am testing imx6dl with android 9 (android_p9.0.0_2.2.0-ga) from NXP in custom board.

The custom board is used our product with linux kernel 4.9.11 + Debian 9 and it is working fine. Have been used for 2 + years.

I ported the device tree and display functions to the android 9 kernel. I can see penguin logo but there is no android logo and no menu.

I have attached logcat and dmesg file. 

Please help. Thank You in advance.

Best Regards,

Pun

Hi All, 

Kernel bootargs:

console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,fbpix=RGB32,bpp=32 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=128M androidboot.console=ttymxc0 consoleblank=0 cma=320M galcore.contiguousSize=33554432

I added androidboot.selinux=permissive and the result is still the same.

Best Regards,

Pun

Hi All,

My board is having this msg:

init: Service 'surfaceflinger' (pid 211) exited with status 1

Hello Chee,

I checked your logcat and doubted that your current issue is "No audio driver support"

08-19 09:50:44.052   371   412 I audio_hw_primary: Total 0 cards match
08-19 09:50:44.053   371   412 E audio_hw_primary: no supported sound card found, aborting.

=> This log indicated that no card (driver support for Audio - audio HAL can't find valid card for audio).

From your kernel log (dmesg.log), You will see "[ 65.085940] init: Sending signal 9 to service 'audioserver' (pid 524) process group..."

In case of audio crashes, You absolutely can't get display.

Hi All,

My custom board does not have these key, I am checking with H/W engineer what these pad is used or not. Do you think these button will cause issue to boot up ?

gpio-keys {

compatible = "gpio-keys";

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_gpio_keys>;

power {

label = "Power Button";

gpios = <&gpio3 29 GPIO_ACTIVE_LOW>;

wakeup-source;

linux,code = <KEY_POWER>;

};
