The board stops working

Nice that your rebuilt the board and got it set up so far.

The issue with no data being read immediately after start-up is because of the glitches described here: zephyrproject-rtos/zephyr#51250
I haven't found a solution other than trying again after a few seconds, yet.

The Instruction Access Fault looks strange. I've never seen that issue. Which exact firmware commit are you using? And did you change anything in the firmware so far? I'll try to reproduce the error.

I tried again. It happened by accident with a high frequency. I found this problem when I pressed S1 button for 3 seconds, then stopped, and then pressed S1 to start. Occasionally, it will get stuck and no error will occur. If it reports an error, such an error will occur.

I seem to understand that it is the error of the computer serial port receiving data. When I plug and unplug the USB cable again, it returns to normal.

@1278043638 With the release of today all issues with the ESP32-C3 serial port should be resolved. Make sure to run west update after pulling the BMS firmware updates.
