Hello,
I am trying to build a Linux virtual machine for RISC V on Debian 10.
I use a tutorial from "GNU LINUX Magazine France" (in French, no 230).
Actually I have got a problem at the last step when "qemu-system-riscv64" is launched.
I set up the cross-compilation toolchain, used debootstrap for the root change and cross-compiled the Linux kernel from the git repository (version 5.1.y).
The pk was compiled with the --with-payload=../../linux/vmlinux option and a 10G disk image was created. Finally I launch the command:
qemu-system-riscv64 -nographic -machine virt -m 1.9G -kernel 2/riscv-pk/build/bbl -object rng-random,filename=/dev/urandom,id=rng0 -device virtio-rng-device,rng=rng0 -append "console=ttyS0 rw root=/dev/vda" -device virtio-blk-device,drive=hd0 -drive file=rootfs. img,format=raw,id=hd0 -device virtio-net-device,netdev=usernet -netdev user,id=usernet,hostfwd=tcp::22222-:22
But the program freezes after the following lines:
