TMS320F280025C: C2PROG couldn't programming with new device

Benjamin,

C2Prog does support F28002x. Can you share the failure snapshot?  

Are you saying that C2Prog V1.8 works for a previous lot of F280025C but not for the latest lot?

Please clarify.

Thanks and regards,
Vamsi

Hi Vamsi,

   Yes, with previous lot of F280025C which worked well but failed at latest lot. 

   The failure snapshot shown as below figure.

Best Regards

Benjamin,

Please ask customer to launch C2Prog via the "C2ProgShell.exe" executable and program the MCU via *JTAG* (not SCI). The console window might provide some additional diagnostic information.

Also, please inquire with the customer if this last lot of MCUs has been programmed before. In particular, find out of these chips have non-default OTP settings.

Thanks,

Beat

Hi team,

   For the device lot couldn't use c2Prog SCI way:  F280025PNS  $7A-09A4XOW        &     F280025CPNS $7A-09A4XEW;

   For the device lot could use C2Prog SCI way: F280025CPNS $7-01AELDW;   

   Updated the information as below figure while run "C2ProgShelll.exe" with JTAG programming. 

Expect for your kindly reply, thanks.

Best Regards

Hello Benjamin,

Thank you for providing the screenshot. This confirms that the problem is not OTP related.

Maybe it is not the device lot that creates the problem, but rather a different lot of boards? Is your customer using TI evaluation hardware, or have they designed their own boards?

To further investigate the problem, I would like to inspect the communication logs.

Please instruct your customer to do the following:

1) create a folder named "c2plogs" in the current user directory, e.g. "C:\Users\jdoe\c2plogs".

2) attempt programming over SCI on a target that exhibits the problem.

3) send you the files named "bootlog.txt" and "loadlog.txt" that will be located in the "C:\Users\jdoe\c2plogs" folders.

Then you can email those files to info@codeskin.com so that I can review them.

Thanks,

Beat

Hi Team,

  The failure reported in customer board, and also echo my previous comments, has done the change with previous old lot F280025 in same board which works well.

  Also I've review the schematic, the board should has no wrong connection.

  I've mailed to you with the log information based on steps your provided.  Expect for your kindly reply, thanks.

Best Regards
