Tool/software: Code Composer Studio

Hi All,

I am using TMS320F28069PZT for my inverter application. When I tried to download or debug program from CCS v5 then it is working fine. But same thing, I am trying from CCS Uniflash 3.4.0 then I am getting following error.

On 1st attempt:

[15:49:11] ERROR >> C28xx: Flash Programmer: Error encountered when writing to flash memory

[15:49:11] ERROR >> C28xx: File Loader: Memory write failed: Unknown error

[15:49:11] ERROR >> C28xx: GEL: File: C:\Users\temp\Desktop\starter 23.02.00\Debug\starter_23.00.out: Load failed.

[15:49:11] File: C:\Users\temp\Desktop\starter 23.02.00\Debug\starter_23.00.out: Load failed.

On 2nd attempt:

[16:03:04] ERROR >> C28xx: Error occurred during flash operation: Timed out waiting for target to halt while executing FlashAPIInterface2806xV1_00.out

[16:03:24] ERROR >> C28xx: Error occurred during flash operation: Timed out waiting for target to halt while executing FlashAPIInterface2806xV1_00.out

[16:03:24] ERROR >> C28xx: Flash operation timed out waiting for the algorithm to complete. Operation cancelled.

[16:03:24] ERROR >> C28xx: File Loader: Memory write failed: Unknown error

[16:03:24] ERROR >> C28xx: GEL: File: C:\Users\temp\Desktop\starter 23.02.00\Debug\starter_23.00.out: Load failed.

[16:03:24] File: C:\Users\temp\Desktop\starter 23.02.00\Debug\starter_23.00.out: Load failed.

Please suggest solution for the same.

Thanks and Regards,

    Maulik,

    1. What are your clock settings in both cases?
    2. What emulator are you using?
    3. Is the device locked?
    4. Can you provide me the .out file? I would like to confirm your problem on my setup.
    5. Are you using a custom board or one of our evaluation boards/kits?(for example LAUNCHXL-F28069M)

    Regards,
    Cody

    Hi Cody,

    1. I am using default clock setting in UniFlash 3.1.0. Screenshot attached herewith.

    2. I am using 510LC JTAG and also tried with XDS100V2. But sometimes in UniFlash, programing is reached upto 80% then i get error.

    3. How can i know device is locked or not?? How to unlock?

    4. I can not provide .out at this stage due to security reason but if issue is not resolved then we will provide it on later stage.

    5. I am using custom board. On same design board there is no issue till now but last 2 board have this kind of issue.


    I can debug code using CCSv5 but can not download it from UniFlash.

    Thanks and Regards,

    Maulik,

    To check whether the device is locked / unlocked. You can do the following:-

    1) Flash memory (or) any other secure memory location would read 0x0000s when device is locked.
    2) If CSMSCR .bit0 = 1, then device is locked

    You can unlock the device if you enter the right password in 0xAE0 - 0xAE7
