PROCESSOR-SDK-AM62X: Unauthenticated boot

Kyle Olson

Tool/software:

I'm attempting to perform an unauthenticated boot on the AM62x HS-FS device. On the SD card, I have replaced both the ti_spl.bin and u-boot.img with their unsigned versions. I've attached a screenshot of the error that I am receiving.

Have we checked the device type on your board?

I have resolved the issue. The tiboot3.bin had to be rebuilt from within the SDK in order for the unsigned versions of tispl.bin and u-boot.img to work.
