Various pieces are missing. In particular, mainstream QEMU doesn't implement the p32 ABI, ELF binaries are handled as o32 and the syscall table doesn't match anything correct. I am sorry but I can not proceed further with this patch. [*] https://github.com/MediaTek-Labs/nanomips-gnu-toolchain/releases/tag/nanoMIPS-2021.02-01
