[Qemu-discuss] qemu-system-arm hangs on OSX

Hello all,

I'm new to messing around with ARM stuff, so I may just be doing something wrong, but I've attempted to follow several sets of instructions like this one:


...albeit using a newer kernel/initrd than the one referenced there, e.g. these:


The problem is that when I run a command like this:

  qemu-system-arm -m 256 -M versatilepb -kernel vmlinuz-3.14-2-versatile -initrd initrd.gz -hda hda.img -append “root=/dev/ram 

a qemu window pops up, but then nothing happens. It just hangs there forever. 

I'm running qemu 2.0.0 installed via brew on OSX 10.9.4.

I can boot things like a regular Ubuntu ISO using qemu-system-i386 (though it's *really* slow), so qemu is working under some circumstances. 

Between a small amount of experience with qemu and almost none with ARM I'm a bit stuck here. Does anyone have suggestions for troubleshooting?

Thanks in advance!

P.S. This is ultimately for testing software to run on a Cubietruck device with a Cortex-A7 processor. I see several -machine types that support a -cpu value of "cortex-a9", "cortex-15", etc, but no -7. Does anyone happen to know what the best machine/cpu combination would be for booting a linux distro designed for the Cubietruck? For example, this one:
