FreeRTOS: RTC interrupt dissapears

[Elena]

Hi everyone

I'm facing a weird problem in my design and FreeRTOS. Apparently, my system was working fine, but along I'm adding more tasks, i've detected the system stops working after a while. This time is random: sometimes freezes at several seconds after booting, some other times after several minutes.

By debugging, I've detected the RTC interrupt stops being triggered. Apparently, it has been disabled. I've to add that in my FreeRTOS configuration, I've disabled the tickless mode.

Any idea about why is this happening?

Thanks in advance

I've found the problem is related to the version I was using of the FreeRTOS port. By using the latest SDK (v11) the problem is fixed. I've found this fix in this other thread: devzone.nordicsemi.com/.../

Thanks for your help
