TMS320F28376D: TMS28376D serial programming with C2Prog

Part Number: TMS320F28376D

Hi all,

I've got a problem with C2Prog and 28376D, during flashing via serial port.

I have used standard procedure of flasing, and the results were:

Bootloading OK.
Chip identification OK.
Device unlocking OK.
Erasing flash [ABCDEFG] OK
During the programing phase, C2prog returns the error: Programming... failed (write error : 509 @8cbc4)

Does anyone idea why it happens, or where can I find the meaning of the error 509, or experienced the same issue ?

My comments and notes.

We have used the hex file many times, with different 28376D chips, and here the flash update went well.

The logic board we experienced the error with, was previously been updated many times without issue.

When we experienced the error the new thing on the process was the PC running C2Prog. However since the previous C2Prog phases went well, the error is not related to the C2Prog and PC setting, like communication time out, Flash width.

Best regards,
