I've had success with Armbian runing on Orange Pi One and pcDuino2. I'm using the legacy kernels on these boards.


Today I've got a pcDuino3B - similar to pcDuino3 except it has GB ethernet from the pcDuino3 nano.

I tried legacy kernels for both the 3 and the 3 nano. I see high cpu load ~35% from one of the kworker processes. Then I tried the mainline kernels from the 3 and the 3 nano. No cpu load problems but the GbE does not appear to be configured in the 3 image. 3 nano works on both ethernet and wifi so I'm wondering whether to stick with this one and see if there are any other differences.

I don't have a build environment set up and no experience with kernel debugging. I'd like to try and resolve the high cpu issue with the legacy kernel so what should I look for or is there any info I can post here that might help point me in the right direction?

Thanks,

Nick.

Added armbianmonitor -m for the pcDuino3B running pcDuino3-nano mainline.

Try to boot mainline kernel with adding:

fdtfile=sun7i-a20-pcduino3.dtb

to /boot/armbianEnv.txt

Thanks for youre reply.

Added. That breaks the GbE - armbianmonotor -u output.
