I'm attempting to run a critical process on Core 1 (A7 processor) while keeping all other processes on Core 0. I've had success with 'taskset' to get my critical process assigned to Core 1. I'm struggling with how to default all other processes to run on Core 0.
Can someone show me how to do this on the supplied OpenSTLinux platform for this processor? The internet mentions isolcpus a lot but I'm not finding support for that command on this processor. How can it be done?

Kind regards,

Not quite. The isolcpus command doesn't appear to be supported on OpenSTLinux, but CGroups appears to be. However, I am having issues writing the file which assigns members of my cpu_affinity group to Core 0. Maybe you could help? Here are my steps to reproduce the issue (all commands worked except for the last step which threw the error):
