Cannot enter TX2 recovery mode

Hi,

That is not UART log. The log from monitor is still kernel log.

Please check below page to know how to dump such log.

sync;sync;sudo reboot --force forced-recovery works on my tx2

and without at least one board with the serial console you will waste a lot of time.

Sorry I have not been able to reply for a long time.
I was able to check the logs when entering the recovery state at UART.

Hi,

I don’t see anything indicates you put the board into recovery mode. It is still a normal boot log.

If you use the command in ubuntu to enter the recovery mode, the uart shall have some log to indicate the board is going to recovery mode. But in your case, it does not show up.

I was able to get the other TX2 into recovery mode using the buttons on the same board.
So I believe that this TX2 has a faulty pin to physically access the recovery mode.

If you don’t have other board to validate, I can only suggest you RMA the whole board.

This TX2 and board have been used with high frequency and I may have caused it to fail.
I would like to keep using it for a while as it can be used as normal except that I cannot physically put it in recovery mode.
Thank you for your kindness in dealing with my problem.

This will only work if it boots correctly, but try this on command line from Linux:
sudo reboot --force forced-recovery
(if any flash after that fails, then you won’t get a second chance via this command)
