Commit [1] removed virtio-blk-device,drive=hd0 from the Qemu command
line since RISC-V virt target now define a default type for block
devices (virtio) [2].
While it's was working as expected using
qemu_riscv{32,64}_virt_defconfig, it doesn't work for nommu variant.
Without "-device virtio-blk-device,drive=hd0", the virtio block device
virtio0 is missing in dmesg:
Expected dmesg log:
virtio_blk virtio0: 1/0/0 default/read/poll queues
virtio_blk virtio0: [vda] 122880 512-byte logical blocks (62.9 MB/60.0 MiB)
Unlike qemu_riscv{32,64}_virt_defconfig, mmu variant doesn't use
opensbi (-bios none) and disable mmu (-cpu rv{32,64},mmu=off)
from the qemu command line...
Adding back "-device virtio-blk-device,drive=hd0" seems to help Qemu
to enable the virtio block device for nommu target.
This partially revert commit [1].

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
