Openwrt on nanopi R5S

Hi,

I've installed an openwrt snapshot on emmc of R5S and everything is ok, i can ping and access the device through web, but there's no HDMI output.

any advice?

Thanks

use ssh ?
it'll provide a scroll back buffer, your HDMI won't.

I want to extend root partition and I want to make sure that everything is normal and the system is booting also sometime I get a new IP from dhcp so it's very important to use hdmi

ok,

then check if there's a console= parameter(s) added to your openwrt kernel boot string, in the boot loader.

Ok I will but how can I change boot param?

see if fw_* from uboot-envtools can do it for you.

HDMI / GPU drivers for rockchip are not enabled yet.
