fixing NanoPi Neo2 shutdown issue

Recommended Posts

I'm testing the nightly image: Armbian_5.32.170704_Nanopineo2_Ubuntu_xenial_dev_4.11.8.img

 

I read somewhere that the NanoPi Neo2 has a shutdown issue where it reboots.

 

This was my experience (serial console) `shutdown -h now` ends with

 

[  OK  ] Reached target Shutdown.
[   59.809788] reboot: Power down
INFO:    PSCI Affinity Map:
INFO:      AffInst: Level 0, MPID 0x0, State ON
INFO:      AffInst: Level 0, MPID 0x1, State ON
INFO:      AffInst: Level 0, MPID 0x2, State ON
INFO:      AffInst: Level 0, MPID 0x3, State ON

Maybe there is a watchdog timer (that resets the CPU if some ticker stops or something) that needs to be disabled?

I see there is no watchdog package installed in this image.

 

As a workaround while connected via serial console, I hit enter when U-Boot got to this line "Hit any key to stop autoboot:  0", which only paused for a very brief moment.
