Hello,
I'm trying to run the cma34cr_centos application from camkes-vm-examples-manifest, but I get this error: "Kernel entry via Unknown syscall, word: 65".
I've set up VMware as described at https://docs.sel4.systems/Hardware/VMware/.
In camkes-vm-examples-manifest/cma34cr_centos_x86_build, I've built the kernel:
../init-build.sh -DCAMKES_VM_APP=cma34cr_centos
Then I ran these commands:
ninja sudo ./seL4vmw.py images/kernel-x86_64-pc99 images/capdl-loader-image-x86_64-pc99 vmrun -T player start $HOME/vmware/seL4/seL4.vmx while :; do socat -d -d UNIX-CONNECT:/tmp/vsock,forever PTY,link=/tmp/mytty done
After VMware boots, I ran minicom in a separate terminal to see the serial output:
minicom -D /tmp/mytty
Here is the full log:
Welcome to minicom 2.7.1

Any idea what's wrong? I just want to get one x86 application with cross VM connectors working.
The other x86 applications (optiplex9020, cma34cr_ubuntu, zmq_samples) in camkes-vm-examples-manifest don't work for other reasons.
