extension zicsr is missing

[LaneaLucy]

hey, i tried to compile linux but i get a shit load of the same error, extension zicsr is missing. anyone know how to fix?

here a example of the error message

/home/lanealucy/litex/linux-on-litex-vexriscv/third_party/buildroot/output/build/opensbi-1.3.1-linux-on-litex-vexriscv/lib/sbi/sbi_ecall_hsm.c:25: Error: unrecognized opcode `csrr s4,0x340', extension `zicsr' required

the only change i made from documentation to get this far is to let buildroot set gcc version higher because other version is depracted

Could you try to comment these 4 lines? without PLATFORM_RISCV_xxx opensbi will detect config by itself.

@trabucayre now i get the following errors...
