Hi,All I am trying to build the seL4 VMM example for the qemu-arm-virt platform from seL4/camkes-vm-exmaples. I can build the vmm image successfully, but I cannot run the image. Here are what I did: 1. I use the "../init-build.sh -DCAMKES_VM_APP=vm_minimal -DPLATFORM=qemu-arm-virt" command. 2. ninja After these two steps, the vmm image, capdl-loader-image-arm-qemu-arm-virt is successfully built. But when I run the generated scripts, ./simulate, to run the VMM on qemu, the vmm fails to boot up. The error message is attached below.
I use Ubuntu 20.04 and QEMU emulator version 4.2.1. Do I miss something here? Do I use the correct version of the building environment? Any help would be appreciated! ./simulate ./simulate: QEMU command: qemu-system-arm -machine virt,virtualization=on,highmem=off,secure=off -cpu cortex-a15 -nographic -m size=2048 -kernel images/capdl-loader-image-arm-qemu-arm-virt ELF-loader started on CPU: ARM Ltd.
