Hi Tim,
Do you have a copy of the QEMU ARM emulator (qemu-system-arm)?
There are some scripts [1] in the kernel repository which uses the emulator to generate a copy of the DTS and DTB of the platform.
Note that for the qemu-arm-virt platform, the minimum required version of QEMU is 4.1.1.
Regards, Damon

Hi,
I am attempting to create a new CAmkES project. So far I have used the https://github.com/seL4/camkes-manifest.git repository and the https://github.com/SEL4PROJ/camkes-arm-vm-manifest repository and placed my .camkes file and components into the respective app folders for each. I then attempt to initialise my project as instructed here https://docs.sel4.systems/projects/camkes/ but it fails. It gives me the following error:
hardware_gen.py: error: argument --dtb: can't open '/workspaces/microimpexor/seL4_build/build/kernel/kernel.dtb': [Errno 2] No such file or directory: '/workspaces/microimpexor/seL4_build/build/kernel/kernel.dtb'
I am initialising my project with the following command:
../init-build.sh -DPLATFORM=qemu-arm-virt -DAARCH32=1 -DCAMKES_APP=appname -DSIMULATION=1
Some assistance on this matter would be greatly appreciated.
Regards
Tim Yates
