![]() ![]() If you compile with -nostartfiles -nostdlib -nostdinc both the toolchains will work the same way. Riscv64-unknown-linux-gnu-gcc that uses glibc and can be used to build programs that can be dynamically linked and executed on an OS like Linux. Riscv64-unknown-elf-gcc that uses newlib and is used for small statically linked standalone programs and embedded targets. Riscv-gnu-toolchain is the toolchain to compile applications for RISC-V. This article brings together the end to end flow into a single document. So, it might be overwhelming for a beginner. There is quite a lot of info already available out there. We will be compiling all the tools from scratch to get a good familiarity with the pieces involved. We top it by booting a standard Linux distro with python support. This article explores how to set up RISC-V on QEMU, boot a simple application on it using the PK kernel, and boot a cross-compiled Linux on the emulation platform. But this need not stop you from exploring the ecosystem. Linux & Python on RISC-V using QEMU from scratchĪs of today, RISC-V hardware is not always easy to come by on a hobbyist budget.
