When following the instructions here, https://openwrt.org/toh/asus/lyra_map-ac2200 I am able to upload the .itb file via ssh and run the install command given, the
reboot -f, but after I upload the .bin file and try the
sysupgrade step, I get an error saying
sysupgrade: not found
Are the instructions missing a step, or am I misunderstanding something here? Any help is greatly appreciated.
