Hi I use this command to compile the demo code. SaxonSoc/software/standalone/blinkRgb$make BSP=FomuMinimal and it report compile fail, here is the output detail。 it seem that the program is rv32i but it use the riscv64 libc.a (64-bit), so link failed. can somebody help me figure out how to solve this problem :(

Hi,

How did you installed your riscv compilation toolchain ?

wuxx commented 4 years ago

I compile the riscv toolchain myself, under /opt/riscv/bin/riscv64-unknown-elf-gcc does I need re-compile the toolchain with addition config flag ? or does there have prebuilt toolchain I could try .

Dolu1990 commented 4 years ago

Personnaly, i'm using the prebuild one described in https://github.com/SpinalHDL/VexRiscv#build-the-risc-v-gcc

Should be fine then ^^

I try this toolchain and compile is ok now, thank you very much! :) https://static.dev.sifive.com/dev-tools/riscv64-unknown-elf-gcc-20171231-x86_64-linux-centos6.tar.gz
