[BPI-R2] How can I power off my BPI-R2?


Now I know how to boot BPI-R2. Just pressing Power button about 10 seconds.

But… how can I safely shutdown it? I searched some articles but I failed to find answer.


You can use my kernels (4.14,4.19,5.4) and simply use poweroff command :slight_smile:

If you use lede,you need to extract patches from my repo and include in your building-process

https://github.com/frank-w/BPI-R2-4.14/commits/5.3-poweroff-new (5.4-mainline contains 6 patches so use 5.3 patches for lower kernel versions)

Really thank you for your answer and sorry for poor problem description.

I’m using your 4.4.160 Kernel (https://github.com/frank-w/BPI-R2-4.4/) (also thank you for the kernel! :blush: )

When I typed sudo poweroff, the SSH connection was closed and the display (HDMI) went out. But I don’t know it’s really shutting downed or not, because all the LEDs are still brightly on.

Yesterday, I got a SDcard filesystem error during boot after I unpluged DC power to completely turn off it. (It was about 30 minutes after I typed poweroff command.)

Is it safe to unplug the power cable after the display turned off in normal cases?

4.4 does not contain poweroff drivers,it is only a updated version (for security,but still old) of official repo.Just use the 4.14 repo

For the bpi-r2, the only sane OS I have found for it is the Armbian image. It’s working great as a Tor relay and as a time server. I would have liked to do yet more with it, but I could not figure out how to do it.

Otherwise, to quickly power down your bpi-r2, just use ‘init 0’.

How about my ubuntu/debian image? Real poweroff only works with poweroff patches. I guess armbian does not have them so it does only a halt,but board stays on (~5w power consumption)
