SK-AM62A-LP: Boot Hangs on SDK 10.01, Works Fine on SDK 09.02

Tool/software:

Hi,

I flashed the prebuilt image from SDK 10.01 and noticed the following U-Boot messages.

U-Boot 2024.04-ti-ga970f6e51043 (Nov 13 2024 - 14:26:23 +0000)

However, the system gets stuck during boot.

I also built the SDK 10.01 image myself, and it shows the same behavior with the same U-Boot messages.

However, when I flash the prebuilt image from SDK 09.02, the board boots and works correctly.

Do you have any suggestions on how to debug this issue?

Thanks.

Hello Justin,

Just to confirm, you were booting from emmc, right?

Thanks,

Jianzhong

Hello Jianzhong,

Boot from SD card.

Hi Justin,

Could you please try to partition the SD card properly and test again?

Hi Jianzhong,

I have partitioned the SD card and extracted the rootfs onto it, but I still encounter the same error messages.

I’m confident that the partitioning was done correctly.
