TMS320F28375D: TMS320F28375D Load Error

Hi,

Is this TI EVM or your custom board? Which example you are trying? Can you try a simple example (led_Blinky) from C2000Ware SDK, just to make sure the code is correct.

This is custom board. I think the device is locked but I am not sure why this has happened. It seemed to only happen when I connect the controller to mac. This is what I get in debug configuration.

I think the device got locked when I connected to mac but I am not sure why since nothing seemed to disrupt. Is there anything I can do to identify what went wrong?

To add more information: I used the flashprogrammingwith dcsm example to check flash programming. Could that example have caused any issues?

Hi.  I need some urgent help regarding this issue. It would be great if you could look into it.Thanks!

Did you made any modification in the DCSM example? By default all the settings are commented out in the example so it should not program any setting but if you made any change then you need to check what is the password value you have programmed and use that value to unlock the security in flash plug-in GUI and then should be able to use it.

I did not make any changes. I programmed as imported from examples.

Ok, if you are able to connect to CCS, please open memory watch window see the content at address @78000 and @78200 and send me the snapshot.

Thanks!

Ok, everything looks ok here and device is not locked. Can you also check the value in NMISHDFLG register in CCS register view.

 Is this what you are talking about?

Yes and everything looks ok to me. Can you post the error again which you are getting while trying to program the code ?

4604.debuglog.zip This is the debug log.

28xx_CPU1: GEL Output:
Memory Map Initialization Complete
C28xx_CPU1: If erase/program (E/P) operation is being done on one core, the other core should not execute from shared-RAM (SR) as they are used for the E/P code. Also, CPU1 will be halted to determine SR ownership for the CPU which will run the Flash Plugin code, after which CPU1 will be set to run its application. User code execution from SR could commence after both flash banks are programmed.
C28xx_CPU1: Error occurred during flash operation: Timed out waiting for target to halt while executing wr_pll.alg
C28xx_CPU1: Error writing the PLL values (Flash algorithm timed out). Operation cancelled.
C28xx_CPU1: Perform a debugger reset and execute the Boot-ROM code (click on the RESUME button in CCS debug window) before erasing/loading the Flash. If that does not help to perform a successful Flash erase/load, check the Reset cause (RESC) register, NMI shadow flag (NMISHDFLG) register and the Boot-ROM status register for further debug.
C28xx_CPU1: File Loader: Memory write failed: Unknown error

We are looking into the log and get back to you.

Hi, I was wondering if you could find something from those debug log files? Thanks!

Yes, we do see some error in these log files and our team is analyzing the same. Please expect a reply in 1-2 days on other post.
