Hi (pjv and others),
Pjv, I adapted your RTOS to have a single preemptive task
that is to be executed as if it were the main interrupt task.
The idea is to have a single preemptive task that executes
at the main code level (but outside isr) at a much lower rate than the
isr itself. The isr is to be used by VP code, whereas the main isr code
is to be used with a timer list to run small routines that are not timecritical.
Having only one task allowed me to save the main code context in the fifo.
Could you comment on this setup?

 

regards peter
