I'm trying to compile my makefiles, but this extension 'zicsr' is missing. I'm using gcc version 13. I have searched everywhere but didn't find a way to add this extension to my toolchain. What's the solution? Do I need to install older version of riscv toolchain?

Me too getting this error replace March=rv32i to March=rv32i_zicsr in Makefile

Thanks Kunal, that worked. I commented above ARCH = rv32i and uncommented below line and now its solved.
