After a few days of fun tinkering, my nano will no longer boot.
The last thing I did was hot-swap cameras on the CSI connector. The new camera didn’t work so I rebooted from shell. Device went down and never came back up.
Green power led lights up, but no activity on HDMI, ethernet.
Things I’ve tried:
different micro-usb power supply
barrel jack power supply with jumper installed
newly created sd cards
J40 jumpers on reset pins
Things I haven’t tried:
monitoring TTL serial output
Any suggestions on how to resurrect my nano?
