maybe wrong with your mips-elf toolchain , https://ai-thinker-open.github.io/GPRS_C_SDK_DOC/en/c-sdk/installation_linux.html

Where do I get a mips-elf toolchain?

[cryarchy]

Thank you. I have discovered that I had installed a custom mips-elf toolchain in a previous attempt at installing the SDK prior to Linux support. I have removed it and all seems to work.
