J721EXCPXEVM: Unable to boot the EVM

Part Number: J721EXCPXEVM

I just received a new J721EXCP01EVM, and I was unable to boot with an SD card using the standard boot configurations. I tested on another EVM with my SD card and it booted just fine. I also switched the J721EX SOM processor board with another one, and it also made no difference. The only difference I noticed on this PCB is that the PCB# PROC079A is the not working one, while the PROC079E3 one was working fine.

    You are not getting any log on the console  ?

    We checked with PROC079A common proc board we are able to boot with the SD card , Do you have another PROC079A as it could be some hardware issue with the CPB
