Did you append root=/dev/vda?

Yes. Generally I dont know what I should append there. An explaination would be appreciated.

Could you try options in #1 ?

Already did that. Still not working. The append flag tells the debian grub where to find the root file system, right?

There is no grub for qemu to boot arm Linux. In other words, qemu itself plays the role of grub.

What errors do you get?

Hello.

I tried setting up the debian on armhf. But I do not know what I should specify as -append flag when starting QEMU. It keeps saying:

Any ideas?

This is the error and it just drops a cell after that. It says it gave up on waiting for root file system device and that it cannot find the filepath that is specified on the -append flag. What do you specify as the root filepath?

Could you give the full command line and your qemu version?

sudo qemu-system-arm -machine virt -cpu cortex-a15 -smp cpus=4,maxcpus=4 -nographic --append "root=/dev/vda"

Of course I have changed the kernel and initrd versions to the latest ones you have uploaded on releases.

Basically I tried again today with the command I mentioned in the above comment and it worked. So I will close the issue. Thank you!!
