Is it possible to disable FreeRTOS ticks on core 1 with IDE Arduino ?

[Langelot]

Hello everyone,

Everything is into the subject. I have searched the internet for that and apparently it seems to be possible but no real solution was explained. I need to do this because I have time critical actions that can't be started by interrupts (too much latency) and that can't be handled by peripherals. So I have created an high priority task that does the job. It works except that the FreeRTOS ticks are stopping the task every milliseconds for some microseconds. It would be great if I could disable these ticks on this core and of course also the watchdog of idle task.

Any idea on how to do that?

Thank you.
