Reboot w/ Carrier Board Doesn't Work

Using the most recent stock Ubuntu image for the Nano, a soft reboot results in the carrier board locking up after shutdown (the board doesn’t come back online). Is there some type of CPU reset process that needs to be added to reboot to facilitate this? Or do all Jetson Nano carrier board power options have to be done via J40?

Hi, J40 is to disable auto power on function, did you try soft reset w/ and w/o jumper J40?

I also have trouble with soft reboot not coming up again.
Similarly, removing power and re-attaching it right away also doesn’t self-boot.
The “solution” is to remove power for more than 15 seconds and then re-attach it.
