I have tried that and built the VM again, but I keep getting the same
mprotect error message :( Any other ideas?

 From: oscogvm/build.linux64ARMv8/HowToBuild:


If running the resultant squeak vm gives an error something like
     memory_alias_map: shm_open: Permission denied
you need to enable shared memory for the COG JIT.

As root:
    chmod 777 /dev/shm
    echo 'none /dev/shm tmpfs rw,nosuid,nodev 0 0' >> /etc/fstab
    mount /dev/shm

The squeak vm should now work.
