But i loose serial output as soon the kernel/systemd is done.
I build kernel with openwrt build system and told it to boot /dev/mmcblk0p1
via CONFIG_CMDLINE="root=/dev/mmcblk0p1 rootdelay=10 console=ttyS2,57600"
Any one know what else i need to compile in kernel?
maybe gpio/serial support for MT7688?
