Part Number: TMS320F280049
Other Parts Discussed in Thread: SFRA, TIDM-02002, POWERSUITE

Tool/software: Code Composer Studio

Hello,

I am working on the C2000 F28004x control card witch has a F280049 microcontroller on it.

I am trying to perform a SFRA analysis but i encounter some isues.

I followed the TIDM-02002 application note but I am stuck at the sfra step :

I can successfully connect to to control bord port COM through usb and the debugg probe works fine: LifeLED for SFRA blink as said in the applicatino note and UART leds Rx and tx also bllink.

But When I start the sweep nothing happens.

Here are some screenshots.

Thank you for your help.

Hi,

I see you have Lab1 selected, please note we only allow SFRA on lab 2 and above.

Can you try with Lab2, this is also how it is documented in the UG

Hello,

Thank you for your response, unfortunately the problem still remains after trying LAb 2 and 6 ( Open loop prim ->sec protections and Open loop Sec->Prim without protections).

Maybe is it a setting/includes/path problem?

If needed I can send you the project folder?

Best regards.

Your project view looks very different than what I will expect specially under the sfra lib folder.

Can you please tell what were the exact steps you used to import the project ?

I tried on my end and am able to run the SFRA sweep as is.

Hello,

I followed the procedure 3.1.2.1 Opening the Project Inside Code Composer Studio in TIDUEG2B application note and I restarted the project from scratch.

I can build the project at this step sweep is written on the interface but it stays stuck and there is no pregression bar( Config:Lab2 , SFRA : Voltage mode.)

Still, at this step I have not changed include options (procedure detailled in SPRUIK4A but not in TIDUEG2B so i don't know if I have to follow these instructions). See below the default settup of the project.
