> From what I can see, the module loader is expecting the architecture to provide `up_checkarch()`, `up_relocate()`, and `up_relocateadd()`. Those hooks are implemented for a few other architectures under `libs/libc/machine/*/arch_elf.c`, but I’m not seeing the same support for MIPS. So this looks more like a missing piece of MIPS support in NuttX than a simple build/config issue on your side. > > One small extra note: because you’re using `mips-linux-gnu-`, the toolchain may also matter here, since NuttX MIPS support is usually more aligned with bare-metal ELF toolchains. But even setting that aside, the immediate problem seems to be that the MIPS-side ELF relocation support for loadable modules just isn’t implemented yet. > > So my honest read is: you’ve run into a gap in support, not a mistake in setup. If you want to get module loading working on MIPS, it will likely need a proper MIPS `arch_elf` implementation and the related build-system wiring. It may also be worth tightening Kconfig in the future so people get a clearer error earlier instead of hitting this at link time. Thank you @aviralgarg05 that is my understanding as well. @wangtao13 since MIPS is very similar to RISC-V, I think you can use RISC-V arch_elf as starting point.
