Hi,
is it possible to disable just specific interrups in the portENTER_CRITICAL of FreeRTOS.
For example to not disable the System event controller interrupt, to ensure System Interrupts are not touched by the RTOS.

Hi Bernhard,
Thank you for your inquiry.
We are looking into this query now. We will get back to you soon.

Hi Bernhard,
In FreeRTOS, the portENTER_CRITICAL function clears the IRPTEN bit in the Mode Control 1 Register, which disables global interrupts. We do not recommend modifying the OS source files, as it might create untested conflicts and affect system stability.
