Using mentioned RV32I Toolchain I generated .s file. I wanted to simulate this assembler code in Jupiter but I have some errors (errors that occured are commented in the line they are related to):

Following the RISC-V Assembly Programmer's Manual: link directives that are used in my code should be fine.

Hi !

The RISC-V toolchain should not be used with Jupiter because the C compiler generates directives not supported (.option, .size, .ident) by Jupiter and other features like numeric labels.
