Does anyone can help with soft float config for this board, given it only has base integer and CSR extensions, I guess i need to implement it using the shifts , logic operation and basic operations.. Berkely's soft float had been tried which throwed up error for usage for multiplication and division usage. So currently I am currently planning to implement the float by writing custom function in assembly and linking them as binary in the current project...Please correct me if I am wrong, also kindly share your views..

compilers like gcc will emit code that implements C standard features that aren't implemented by the ISA: https://godbolt.org/z/5WjjEcsaY
