After running for a long time, TX2 suddenly doesn’t work. After restarting, it can’t enter the system.
Connecting the serial port, it is found that the printing is as follows:
!!! Exception !!! [lr:0x40021cea, dfar:0x22150a0 , dfsr:0x1808 ]
MB1-BIT() boot status dump:0000000000000000000000000000000000
Last seen error : 0x00000000
Moreover, TX2 cannot enter recovery mode
According to the serial port log, what happened to TX2? Can someone locate the cause of this problem?
