Yes, I did.

In buildroot:
$ make qemu_riscv64_nommu_virt_defconfig

The QEMU command line generated by buildroot:
qemu-system-riscv64 -M virt -bios none -kernel output/images/Image -append "rootwait root=/dev/vda ro" -drive file=output/images/rootfs.ext2,format=raw,id=hd0 -device virtio-blk-device,drive=hd0 -nographic -cpu rv64,mmu=off # qemu_riscv64_nommu_virt_defconfig

Compared to a regular riscv64 QEMU command line, the relevant parameter is:
-cpu rv64,mmu=off


Kind regards,
Niklas
