sarfaraz shaikh

Part Number: AM6548

Hi On our custom board e are getting the below. errors. We are using silicon V2 for our sutom board and SDK 7.0.1.6. We did not try it on IDK as we do not have IDK board for V2 but we tried with V1 IDK board and did not get this errors during booting as V1 id not have txpru cores.

Hi,

Can you try with SDK 7.1 which has just been released ? It has better support for SR 2.0 firmware.

Regards
