Compiler/CC1312R: EasyLink_enableRxAddrFilter() causes system halt

Hi,

After trace code I found that when I use EasyLink_enableRxAddrFilter() for runtime change rx addr filter, it causes system halt.

I use UART for sending addr data and call EasyLink_enableRxAddrFilter().

Finally I found it halt at line 1563 "if ( Semaphore_pend(busyMutex, 0) == FALSE )" in EasyLink.c

How can I avoid system halt when use EasyLink_enableRxAddrFilter() ?

Thank you.

Hi Chris,

Could you elaborate on how you are using this call in your code and in what context (sharing a code snippet would be helpful)?

Hi M-W,

I attached a sample code, just connect uart to dio2 and dio3 then press keyboard for trigger EasyLink_enableRxAddrFilter().

Add init_rx_addr_filter(), set_rx_addr_filter(uint8_t *rx_addr);

Add uartecho.c, copy from TI Driver example.

Please help to check, thank you.

Hi Chris,

I don't see your program hanging in the Semaphore_pend (which is non-blocking as time out is set to 0).
However, I can see that you sometimes the semaphore can not be acquired and the program therefore call an System_abort which halts the device (line 43 in NodeRadioTask). Could this be the issue you are having?

Hi M-W,

I can't understand about "line 43 in NodeRadioTask", if you mean NodeRadioTask.c, line 43 is "#include <ti/sysbios/knl/Clock.h>".
My problem is when call EasyLink_enableRxAddrFilter() by uart thread, the system halt, if not call EasyLink_enableRxAddrFilter() the system is running normally. Maybe it's not hanging in the Semaphore_pend() I still need a way to avoid this problem.
Thank you.

Sorry for that, I think my either me or my keyboard is getting slow, it should be 543, not simply 43!
WHat you should verify is if your system hangs due to line the System_abort, because if this is the case, then you simply need to re-work how you handle a "non success" status from the API call.
