TX2 can not boot up

Hi all,

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?


If even cannot enter recovery mode, then it is possible a hardware issue. We cannot help from software side.

How did you know it cannot enter recovery mode? lsusb does not show anything?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Hi XavierSu,

Is this still an issue to support? Any result can be shared?
