CC1352P: How to reset RF core separately?

Hi Nick,

Would the following answer work for them? https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/1160174/cc1352p7-ability-to-reset-the-rf-cpu-from-the-application-processor

Hi Arthur,

The customer observed that when the program executes a certain Easylink_receive(), (the timeout time is set to 40ms), it will always block inside it and cannot exit. In this regard, they determine that the RF core is dead, and they want a way to reset the RF core to solve this problem.

They think that the program may block at Easylink_receive()-->RF_pendCmd()-->SemaphoreP_pend(&h->state.semSync, SemaphoreP_WAIT_FOREVER); after analyzing the source code of Easylink_receive() and RF_pendCmd().

At this point, if RF_close() and RF_open() are called in other tasks, they think it is invalid because Semaphore is occupied.

Is there any further solution?

Best Regards,

Hi,

At this point, I do not think it is the RF Core that crashes, but most likely EasyLink that is doing something wrong. Could they share the part of their code where it is blocking?
