setting default options for i/o ports

Sun Jun 24, 2018 3:28 pm

I want to ask is possible to set default states for gpio ports, i need to do this because i have custom board for vocore which have connections to external circuits. after vocore boots i set all gpio as i need it, but during boot process there is some problems because ports default configuration, is it possible to do this ? i made a little research and i suspect that i need to do this in device tree file(.dts), am i right, can anyone maybe have some example, how to do this on vocore?
Greetings ;)

This have to be done in bootloader.
Please check and get the bootloader source code, add register control for gpio default value, that's the most simple way.

Return to VoCore2
