Hi ,
I’m using Jeston 5.1.2 on our custom board.
sometimes I got cbb error as below:

It doesn’t happen every time, it happens about 50% of the time
However, in more serious cases, cbb errors may pop up continuously, causing the computer to fail to shut down, until the watchdog is triggered to reset
How can I confirm what device is causing this from wht cbb error address?
