What I want to achieve is that the widora works as a client on the system so not as a router, but in fact as a regular pc. I want to reach it over the network through ssh and it should work with upmpcli as a pnp renderer and with squeezelite as a squeezebox client connected to my amplifier (old Kenwood KR5400).
Is it possible for me to operate on the board? Changing the stuff is actually in the overlay partition. Execute firstboot or jffs2reset -y will be restored as ever.
But I'm not sure if it's the latest firmware, see here: github.com/widora/openwrt_widora , The latest firmware is 0.1.7(chaos calmer)
