Re: [Qemu-arm] Unable to run QEMU with ubuntu ARM image on mac.

[dharmik thakkar]

Hi Peter,

I am trying to run arm based kernel using qemu on mac. I have build the kernel image using linux 4.4.6 for arm architecture. I am using the below command but I don't see kernel booting. While building the kernel i used the defconfig for arm which was versatile_defconfig. 

Try 1: 

qemu-img create -f qcow2 linuxarm.qcow2 10G

qemu-system-arm -hda linuxarm.qcow2 -kernel vmlinuz-4.4.6 -initrd initrd.img-4.4.6 -m 1024 -M versatilepb

A black blank screen appears without displaying anything.

Try 2: 

qemu-img create -f qcow2 linuxarm.qcow2 10G

qemu-system-arm -hda linuxarm.qcow2 -kernel vmlinuz-4.4.6 -initrd initrd.img-4.4.6 -m 1024 -M versatilepb -cdrom 2015-04-06-ubuntu-trusty.zip -boot d

A black blank screen appears without displaying anything.

Point out if I am missing something in the process.

Regards

Dharmik

This command line does not specify either:
   (a) a kernel to boot via -kernel
or (b) a BIOS image to boot via -bios (like UEFI)

So the emulator starts trying to execute instructions starting at
address zero, which are all NOPs until it reaches the end of the
emulated flash memory at 0x800000. Then it gives you this error.

You should change your command line one way or the other.
