TMS320F28P650DK: cannot load codes to flash after unlocked when DCSM is enabled

TMS320F28P650DK: Cannot load files after enable DCSM function

Part Number: TMS320F28P650DK

Tool/software:

hi, 

my CCS version is 12.7.1, after enable DCSM function, it can connect to CCS, but when I try to load new firmware, it will erase successfully but load failed, related warning is as below

I have tried to uncheck the setting as below, but it did not help. 

When I delete the GEL file, the program loads successfully. However, I have to do this for both CPU1 and CPU2, which is quite complicated. Could you help me find out why this happens? The GEL file is attached.
f28p65x_cpu1.gelf28p65x_cpu2.gel

    Hi Chen,

    The thread has been assigned to the expert. Please expect a slightly delayed response as the expert is out-of-office today.

    Hello,

    The GEL file likely has a CSM_Unlock function that is being called using the default DCSM passwords, or whatever passwords you have manually entered into the On-Chip flash tool GUI near the DCSM Unlock option.

    If you want to include the GEL file you may need to manually edit the CSM_Unlock function to use your custom passwords or enter your custom passwords in the On-Chip flash tool if the CSM_Unlock function is taking the password values from the GUI.

    Thank you,

    Luke
