i.MX8M Mini EVK Android 11 Error

territao — Sat, 09 Apr 2022 03:54:54 GMT

Hello,

I downloaded Android 11 demo images to the i.MX8MMini EVK board via uuu, the first time everything works fine and the EVK can successfully load Android 11. The second time I download the same demo images, the LCD continuously shows the Android boot splash screen and outputs the below error messages.

Is there anything wrong with the uuu download process? What does the error message shown below mean?

How do you flash images?

Can you reflash again?

download android-11.0.0_2.2.0_image_8mmevk prebuilt files
execute uuu_imx_android_flash.sh script produce uuu.lst file (evk w/mipi-panel)
set evk switches for serial download
run uuu uuu.lst
set evk switches for mmc boot

On boot, the mipi-panel shows the android boot animation screen indefinitely. The serial console shows android init error (/system/bin/credstore) repeatedly.

If we flash older android_o8.1.0_1.5.1_8mm-beta_image_8mmevk prebuilt files, android boots correctly. And flashing android-11.0.0_2.2.0_image_8mmevk prebuilt files when android_o8 files have been installed, android-11 also boots correctly. But this only works once. Reflashing the same android-11.0.0_2.2.0_image_8mmevk prebuilt files a second time results in the repeated android init error and boot animation screen forever.

Update: the /system/bin/credstore error due to missing /data/misc/credstore directory is a symptom of failing to mount /dev/block/dm-8 on /data. When the system boots correctly, /dev/block/dm-1 thru dm-8 exist. When the system fails to boot completely, /dev/block/dm-5 thru dm-8 are missing. This behavior occurs when using u-boot-imx8mm.imx.

We discovered that if we use trusty bootloader u-boot-imx8mm-trusty.imx, /dev/block/dm-1 thru dm-8 always exist after flashing and this problem does not occur. My understanding is the trusty bootloader is not required, but we have decided to start using it for now as a workaround for this issue.

Any insight as to why the u-boot-imx8mm.imx bootloader fails would be appreciated.
