I download the necessary dependencies and type make qemu in xv6's directory, it seems some troubles happened:

I don't know what does it means and how to solve it. But it seems I have to exit it by ctrl + A + x rather than ctrl + c, which indicates that the problem may come from qemu.

My device:

MacBook Pro m1,
macOS 11.4,
qemu 6.0,
riscv64-unknown-elf-gcc (GCC) 10.2.0

And I have tried sudo make qemu as well, it did not work.

TrenDavi commented 2 years ago

I am running Qemu on a M1 too. Ending up having the exact same error when trying to boot. :(

knightsc commented 2 years ago

The comments on this thread make it sound like Qemu was patched in May to address this issue.

Perhaps try using Qemu 6.1.0

tresf commented 1 year ago

I'm not sure if this is the right place to post this, but at time of writing this, homebrew has qemu 7.2.0, which works pretty well with riscv.

@tresf Yes, it works now. It has been supported by qemu right now : )
