Hi, Why do you want to use maximum operating frequency 130KHz? I don't recommend so high frequency with the high input voltage 1350V.
We need to short the ground 1, 2, 3.
1. Are you testing on a TI EVM? Is it the SK-AM62B-P1 board?
2. What SDK version are you using?
3. Can you share the full boot log including the error (use Insert > Code)?
4. Can you share a Wireshark capture of when the error occurs?
