The XC32 used to work years ago but I don't think anyone has used it in
the last 5 years or so. I would not recommend it. It is non-standard
and very likely incompatible. I would instead recommend any
mips-elf-gcc tool chain. There are several perbuilt MIPS toolchains
available. You can build a newer toolchain for yourself following
instructions on the internet or using the NuttX buildroot. The Pinguino
toolchain is a standard MIPS GCC toolchain but renames the binaries for
its branding. The last time I looked, the Pingquino toolchain was very
old and had not been updated recently.

Pinguino does work without a glitch.

Hello,
Has anyone tested the pic32 build lately? I am using the pic32mx7mmb.
Yes, MIPS target is on the CI checklist:
https://github.com/apache/incubator-nuttx-testing/blob/master/testlist/other.dat#L13-L22
It is setting the processor as '-mprocessor=elf32pic32mx' for the xc32
compiler.

Could you try Pinguino toolchain which is used in CI build:
