TMS320F280049C: Question about the DCSM module

Part Number: TMS320F280049C


Hi team:

CCS V10 with compiler vision V20.2.0.

One of my customers reported an error when loading the project containing the file f28004x DCSM z1otp.asm:

C28xx_CPU1: GEL Output:
Memory Map Initialization Complete
C28xx_CPU1: GEL Output: ... DCSM Initialization Start ...
C28xx_CPU1: GEL Output: ... DCSM Initialization Done ...

C28xx_CPU1: File Loader: Memory write failed: Unknown error
C28xx_CPU1: GEL: File: E:\My Project\DVR\DVRSlaverLock\Debug\DVRSlaverLock.out: Load failed.

And below is his "f28004x_dcsm_z1otp.asm" code:

.sect "b0_dcsm_otp_z1_linkpointer"

.long 0x1FFFFFFF ;B0_Z1OTP_LINKPOINTER1

Would you provide a solution?

    Deng,

    Default value for following sections are not defined properly.

    .long 0xFFFFFFFF ;Z1OTP_PSWDLOCK
    .long 0xFFFFFFFF ;Reserved
    .sect "b0_dcsm_otp_z1_crclock"
    .long 0xFFFFFFFF ;Z1OTP_CRCLOCK
    .long 0xFFFFFFFF ;Reserved
    It need to be like below -

     .long 0xfb7fffff     ;Z1-PSWDLOCK
     .long 0x7fffffff     ;Reserved

          .sect "b0_dcsm_otp_z1_crclock"
       
     .long 0x4bffffff     ;Z1-CRCLOCK
     .long 0x3fffffff     ;Reserved

    Dear Vivek:

    My customer said that he has followed your prompts, but there will still be an error, but the content of the error has changed:

    C28xx_CPU1: GEL Output:

C28xx_CPU1: GEL Output: ... DCSM Initialization Start ...

C28xx_CPU1: GEL Output: ... DCSM Initialization Done ...

C28xx_CPU1: GEL Output: ... DCSM Initialization Start ...

C28xx_CPU1: GEL Output: ... DCSM Initialization Done ...

C28xx_CPU1: GEL Output: ... DCSM Initialization Start ...

C28xx_CPU1: GEL Output: ... DCSM Initialization Done ...

C28xx_CPU1: Error during Flash Verification. Address 0x00078019, Expected 0x00009FFF, Read 0x0000FFFF

C28xx_CPU1: File Loader: Memory write failed: Unknown error

    Hi Vivek:

    Do you have any other suggestions?

    Deng,

    Are they trying the same device? Please note that once user program the incorrect value in OTP (which they have done in this case), they can not change the value. They need to replace the device and try new .out file with correct settings.

    Dear Vivek:

    Yes, he has tried to change the device but it doesn't work.

    But my customer hasn't replied to me recently. Maybe you can close this post.

    Thank you for your help.

    Best regards
