Part Number: LAUNCHXL-F28379D
Other Parts Discussed in Thread: SFRA, , TMDSCNCD28379D, TIDM-1000

Hello E2E Experts.

Good day.

We are trying to use the SFRA application with LaunchXL-F28379D and we are facing an issue with connecting SFRA-GUI. We have downloaded the example code provided by TI onto the MCU, still, the issue persists. We posted queries regarding the issue on the E2E form but none of the solutions worked for us.

Regards,

CSC

    Hi CSC,

    Could you let the customer to check the SCI ports to see if it set correctly?

    Hello Qing,

    Good day.

    Yes, the SCI ports chosen are RX 43 and TX 42 as per launchXL-F28379D.For your reference, the SFRA setup code is attached.

    Is it possible to have customer using  TMDSCNCD28379D on docking station and refer to both software and hardware connections in TIDM-1000? Feel it is better to have a base case to have connections verified on the same chip.

    After it is done, they can check what is the issue, if any, with Launchpad + customer's code.
