AWR1843: How to disable interrupts in run time

Tanoop Rajan

Part Number: AWR1843

Tool/software:

Hi,

I’m curious about how to safely disable and then re-enable interrupts, such as CAN RX interrupts, during runtime for the execution of specific tasks.

For example, I want to disable CAN-related interrupts during the execution of MmwDemo_mboxReadTask() in the MSS core.

Is there a safe way to do this while avoiding race conditions?

Thanks and regards

Hello Tanoop,

In critical sections you are supposed to clear all interrupts, I don't suggest disabling only CAN interrupts.
What you are looking for is done by doing proper task management and prioritization.
