Even better if you could submit some .rst pages for QEMU's git: docs/system/target-riscv.rst docs/system/riscv/virt.rst (and maybe the other models) then we could improve the user manual where RiscV is currently a little under-represented. A number of the systems have simple example command lines or explain the kernel support needed for the model. > >>> sudo qemu-system-riscv64 -nographic -machine virt \ >>> -kernel linux/arch/riscv/boot/Image -append "root=/dev/vda ro >>> console=ttyS0" \ >>> -drive file=busybox,format=raw,id=hd0 \ >>> -device virtio-blk-device,drive=hd0 >>> >>> But what I get in return is a message telling me that the file I gave >>> wasn't the right one, the actual output is: >>> >>> qemu-system-riscv64: -drive file=busybox,format=raw,id=hd0: A regular file >>> was expected by the 'file' driver, but something else was given >>> >>> And I checked the file busybox with de cmd "file" and got the following : >>> busybox: ELF 64-bit LSB executable, UCB RISC-V, version 1 (SYSV), >>> dynamically linked, interpreter /lib/ld-linux-riscv64-lp64d.so.1, for >>> GNU/Linux 4.15.0, stripped >> >> That looks like an ELF, which won't work when attached as a drive. >> >> How are you building this rootFS? >> >> Alistair >> >>> >>> So I was wondering if the error message was related to qemu. >>> Thanks in advance for answering any suggestions are welcome -- Alex Bennée
