Hello Bin,

With the patch I can run U-Boot

qemu-riscv_smode_defconfig
CONFIG_MTD_NOR_FLASH=n
CONFIG_CMD_NET=n

with QEMU 7.0 using KVM using command

qemu-system-riscv64
         -M virt -accel kvm -m 2G -smp 2
         -nographic
         -kernel u-boot
         -device virtio-net-device,netdev=eth0
         -netdev user,id=eth0,hostfwd=tcp::8022-:22
         -drive file=riscv64.img,format=raw,if=none,id=NVME1
         -device nvme,drive=NVME1,serial=nvme-1

and boot Linux from it.

But whenever virtio is accessed by U-Boot QEMU crashes without output.

E.g. after 'virtio scan' even CTRL+A,C is ignored.

Did you have more success? Any clue how to debug this?

Best regards

Heinrich
