Hello to all.
I just tested 32 bit runtime for PI on a Raspberry PI 4, 5.4.51 kernel compiled by me from scratch after patching it to PREEMPT RT.
I isolated core 1 from the CPU leaving the cores untouched 0,2,3.
Codeyscontrol changed to init.d, and taskset on isolated core.
I achieved an average jitter about 28-30us and some peaks about 100us.
However, I notice that the runtime dies every 50-60 seconds after starting.
Do you think this is due to the fact that I used a 64bit Raspberry OS?

at the moment it is not tested/made for 64bit.
So I would recommend to switch back to 32Bit OS.
