TIDA-00374: Software problems - finite state machine endless waiting

Anika Miltenberger

Part Number: TIDA-00374

Hello guys,

I am trying to develop my own board based with the reference design from TIDA 00374 project.

I can flash with the CCS with no problems and can debug with the XDS110 Debug Probe, but I cannot see the Packet Sniffer data.

In the debugger mode I can step in main.c through the RF_postCmd that call the RF.c .

    /* Set the frequency */
    RF_postCmd(rfHandle, (RF_Op*)&RF_cmdFs, RF_PriorityNormal, NULL, NULL);

In  the program code in RF.c is a fsm with

- fsmPowerUpState

-fsmCpeState

-fsmSetupState

-fsmActiveState

-fsmPowerDownState

-fsmPowerDown2State

I can step through this fsm until fsmSetupState. The code will never go to the fsmActiveState and I don't know why. I suggest the relevant interrupt to jump to the next state is missing?

All ideas and suggestions are very welcome!

    Can you provide more details on your software setting?  E.g., which firmware are you using, and which SimpleLink SDK version?

    If you compile the TIDA-00374 firmware with the wrong SimpleLink SDK version, you might run to errors.  Therefore to test sending a radio packet, run the rfPacketTx example code provided in the SimpleLink SDK first.  This example code has been validated to work with the SDK.
