hi

Apparently CONFIG_DEVMEM=y is not set for these builds.

It is very handy to have it set, so one can upgrade the bios on the pcengines APU boards using flashrom.

root@router:/disk/pcengines/apu4/bios# flashrom -w apu4_v4.11.0.6.rom -p internal flashrom v1.0 on Linux 4.14.195 (x86_64) flashrom is free software, get the source code at https://flashrom.org

I'm also having this error. Is there a workaround so I can flash the new APU firmware to the board from within OpenWrt?
