换成这个工具链再试试？ https://download.rt-thread.org/rt-smart/riscv64/riscv64-linux-musleabi_for_x86_64-pc-linux-gnu_180881.tar.bz2

Why not put this toolchain URL in the "bsp/qemu-virt64-riscv/README.md" directly? I've failed with toolchains in ubuntu repository (like gcc-riscv64-linux-gnu) and both 10.2 and 11 in musl.cc.

qemu-virt64-riscv 这个BSP不支持SMP吧
