Hello,
I'm using the NanoPI Neo 512M with OpenWrt and I wrote a C application that uses some GPIO lines.
Everything works as expected, but when I power on the NanoPI board, I see GPIO lines to quickly "flap". It's easy to recognize because there are some leds connected to the GPIO lines.
Is it possible to set the status of GPIO lines (or some of them) as low output when the board starts? I'm not talking about OpenWrt: after the OS starts, I know it's easy to do that. I want to set the status in the bootloader or somewhere at the very early stage of the boot process.
Thank you.
Marco
