AM625: SK-AM62P-LP Unable to enable V3 Link on Android SDK

Hi,

normaly if you device tree overlay was ok you don't need to load manually driver  system should load it itself.

for no log it's becasue we put quiet in kernel commandline so we don't see a lot of lot by default in serial console , you can you dmesg command from console or adb shell in root mode.
if you want you can rebuiltd android and remove 'quiet' from BOARD_KERNEL_CMDLINE in 'device/ti/am62x/device-common.mk'


i don't have this expension card so difficult to test in my side, to you test it on linux bsp before move on android ?

if you can share more log from logcat dmesg etc.

Regard,
Guillaume

Dear Guillaume,

I will share the log on coming Monday. Is it possible for your to verify my patch?

If not for dmesg logs, atleast "adb shell dumpsys media.camera" should have listed the cameras. However, it didn't listed in our case.

So I assume, there was some issue in the patch. Soo could you comment on the patch?

Best regards,

Libin Jose.

Hi,

your patch look good except for part in k3-am62p-main.dtsi because node should be enable when you load device tree overlay.

but as i say i don't have V3 Link daughter board so difficult to validate it.

and As i read in your first e2e imx  sensor was not supported except to capture raw images so this sensors will probably not works on android too.


adb shell dumpsys media.camera list camera which are good option to works with android.

you need to use cam -l command to see if camera HAL find you camera and accept it.

do you check with lsmod command if imx219 and DS90UB960 driver was loading ?

Dear Guillaume La Roque,

I don't see imx219 in lsmod. However, when I insert them manually, there seems to be no error.

Any idea?

Hi,

if you imx module not laded automatically at boot it's probably because you have an issue in device-tree , you can chek in /proc/device-tree/  if you find compatbile 'sony,imx219' and same check if driver for serializer was insmod too : https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm64/boot/dts/ti/k3-v3link-imx219-0-0.dtso?h=ti-android-linux-6.6.y#n47
