R32.3.1 tx2 "sudo reboot --force forced-recovery" does not work, just hangs

linuxdev pointed me at this, I tried it twice and it just hangs my tx2

Looks like a bug, when will this be fixed?

Hi terrysu50z,

We have used that command to set the TX2 into recovery mode and flash JetPack through SDK Manager.
The command line terminal hangs after running the command, you cannot access the board using SSH.

Is this your use case?
We use that method with remote connections.

Hi terrysu50z,

We can’t reproduce this issue.
When we run this command, the device can boot into recovery mode success.

$ sudo reboot --force forced-recovery
Using 'lsusb' check on host machine, we can see the NVIDIA device.
$ lsusb
Bus 001 Device 115: ID 0955:7c18 NVidia Corp.

One thought I have on this is that even if the command would normally work, should there be some shutdown component which hangs/blocks, then you’d never see recovery mode. As an example, in a normal shutdown a failed filesystem umount could block the remaining steps of a shutdown. Recovery is only reached after full shutdown and then beginning of a special case boot.
