If I suspend the execution in QEMU, the program counter is at 0xe00108ec. In the kernel, that is the <idle_thread> method. So perhaps the system is running, but I'm just not able to see any output from the elfloader, kernel, etc.

Thanks Alex. That fixes the crash. Now the system runs but just seems to hang without doing anything. I don't get any output at all (whereas the kzm version spews out a ton of messages). In 'top' I can see it's using about 3% cpu so it's something, though it's not clear what. It's hard for me to tell. Perhaps the UART for the console isn't working correctly?

Hi Andrew,
It could be because QEMU does not know how much RAM is available. Could you try adding "-m size=512M" to your arguments?

I'm trying to build and emulate a version of seL4 for the zinq7000 platform, but it crashes immediately.
I've started by taking the camkes tutorial and building it for zinq7000:
repo init -u https://github.com/seL4/camkes-manifest.git repo sync make arm_simple_defconfig make menuconfig # change seL4 platform to zinq7000 make
When I try to emulate it, it crashes right away:
qemu-system-arm -M xilinx-zynq-a9 -nographic -kernel images/capdl-loader-experimental-image-arm-zynq7000
qemu: fatal: Trying to execute code outside RAM or ROM at 0x10000000

Is there something I'm doing wrong?
