RISC-V compilation fails

[mwyborski]

Hi!

The board manager already downloads gcc-7, but the compiler settings in platform.txt seem to be outdated. Right now it is not possible to compile for RISC-V.

I tried with -march=rv32i -mabi=ilp32 but i get still errors. If gcc-7 is unstable maybe it is better to revert to the previous toolchain?

Here are the compiler options for risc-v

Hi!
Try the following options: -march=rv32i -mabi=ilp32 -mno-fdiv -mno-div instead of -m32 -msoft-float -mno-muldiv in both c flags and ccp flags.
it works for me

@amassou2017 thank you very much! I will try it with the additional flags.
