TMS320F28379D: Uniflash: Memory map prevented reading 0x7801C@Program

Part Number: TMS320F28379D
Other Parts Discussed in Thread: UNIFLASH

Hello,

after succesfully flashing with the Uniflash tool, i got this error, when i pressed the "Verify Image" Button:

 [ERROR] C28xx_CPU1: File Loader: Verification failed: Memory map prevented reading 0x7801C@Program

meanwhile i got out, that this is the adress of the Z1-PSWDLOCK, but i not touched this register.

Maybe thats the result, because i changed the BOOT-Pins from the default pins to other.

I added the Gel-file, maybe it can help.

Best Regards

  • Julian,

    Which version of Uniflash tool you are using? Can you check your map file and see if there is anything mapped at this location?

  • Vivek,

    currently I use the Uniflash version 4.2.1.1562.

    It looks like that the PSWDLOCK use this memory space.

    It is listed in the MEMORY CONFIGURATION and in the SECTION ALLOCATION MAP.

    I will attach the map file below.

    In the download settings in Uniflash I checked the option "Verify Flash after Program".

    After every flash progress I get the message "[SUCCESS] Program Load completed successfully".

    I think that means that in this case a part of the flash progress is the verification and if the flash progress is successful, the verification is successful too.

    Is it possible that Uniflash restart the µC after flashing (I think that happens automatically, because Uniflash has for this µC no option for "restart after flashing")

    and when I try to verify after this restart I can't read the orginal informations from the flash memory?

    regards

    Julian

  • Julian,
    Is this issue same as one below -

    e2e.ti.com/.../2797300

    If yes, then we would like to close one of the post and continue debug/discussion on other one.

  • Vivek,

    I don't know if this 2 problemes are the same.
    One is on cpu 1 occured and means " prevent reading" and the other is on cpu 2 occured and means "program do not match".
    Do you think this 2 problems have the same root cause?

    Regards,
