Qemu 9.1 recently fixed the RISC-V virt target by adding the missing
default type for block devices [1].
But the qemu command line we use for RISC-V virt is slightly incorrect:
-drive file=rootfs.ext2,format=raw,id=hd0 -device virtio-blk-device,drive=hd0
With Qemu 9.1, this command line now rejected since it conflict with
the new default bus:
qemu-system-riscv64: -drive file=rootfs.ext2,format=raw,id=hd0: Drive 'hd0' is already in use because it has been automatically connected to another device (did you need 'if=none' in the drive options?)
Since we are currently still using Qemu 9.0, apply the suggested change by
adding 'if=none'.
Note: '-drive file=rootfs.ext2,format=raw,id=hd0' can be removed
in a followup patch after the qemu version bump 9.1 is merged.

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.
