GPIOs config on DTS


#1

Hello,
Im using a custom board with wp7702 derived from mangoh green. I would like to know how to change direction and value of some GPIOs very early at boot. It is possible by editing the dts or in some kernel module?

Thanks
M.

How early, exactly, is “very early” ?


#3

the sooner the better :slight_smile: , during kernel load before init would be great.
