TMS320F280039C: SFRA GUI cannot connect

Cherry Zhou

Part Number: TMS320F280039C
Other Parts Discussed in Thread: SFRA

Hi team,

Here's an issue from the customer may need your help:

Example 1_STB_f28004x_F32_TTC_eabi demo for card porting, with the corresponding serial port and baud rate selected, click Connect at "SFRA _GUI.exe", and it will report “Could Not Connect: Please Check Connections"

Customer can receive data at break point in SFRA_GUI_getCmdByte function, but it always prompt cannot to connect.

And is there any demo available?

Could you help check this case? Thanks.

Best Regards,

Cherry

Hi Cherry,

You can refer to the ref design below which gives both 3x and 4x code with SFRA.

Did they update the SFRA uart clock for the new design? The F280039C has a 30 Mhz low speed clock by default, compared to 50 Mhz for the F280049C. It is defined by SCI_VBUS_CLK in that example.

Hi Cherry,

Is the issue resolved? Can we close the thread or the customer is encountering the issue?
