Hi TI Team,

We have the SK-AM62-LP EVM Board, and try to flash the Image from TI site as below baisic SD Card type.

 

Processor SDK LINUX AM62xx-LP Yocto - SD card image:

https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-PvdSyIiioq/11.02.08.02/tisdk-default-image-am62xx-evm-11.02.08.02.rootfs.wic.xz

 

But we can not boot this image successfully, Console Log as below:

    I want to know the EVM version first, what is the 'PROCxxxx' label printed on the EVM PCB?

    Please use the following sdcard WIC image. it's name has "am62xx-lp". The WIC image you linked above is not for the PROC124E2A EVM.

    I tried the same process flashed to two different types of sdcards, but both cards can boot my SK-AM62-LP properly, I am not sure how to replicate the issue on my side.

    Can you please try a different type/brand of sdcard to see it still fails?

    I am able to reproduce the problem with a different sdcard.

    I will look into it and get back to you once I have an update.

    I tested with several sdcards which are the same brand/type as the one fails to boot, but all those cards can boot into U-Boot prompt properly. So basically I have only a single card which shows the problem.

    Please try with different cards on your board to see if you still face the issue.
