I have AGH installed on my Spitz, but I don’t recall if the QCA9531 CPU (same as Mudi) used 32-bit mips or mips LE for the AGH install to /opts. For the mips_24kc, I’d try the 32-bit mips first (uname -m shows mips).

These commands from SSH work on a variety of platforms too to figure out the architecture.

opkg print-architecture

ubus call system board

uname -m
