CCS/TMS320F28379D: TMS320F28379D

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

I run the same SW out of RAM with SYSCLKDIVSEL 0 or 1 without any issue, however if I initialize SYSCLKDIVSEL = 0 to make ePWM frequency = 100MHz then the SW does not run out of FLASH. What am I missing to initialize yet?
Thank you,
Victor

    Victor,

    When do you see this error pop-up? Do you have real-time mode enabled in the Debug settings of your project? When real-time mode is enabled, emulation and debug accesses are normally blocked so depending on what you are trying to do, the debugger may be trying to make accesses which are blocked. Please see this related thread for recommendation on when to enable real-time mode.

    The link below also has some references on using real-time mode that may be helpful:

    The problem is to run SW out of FLASH with SYSCLKDIVSEL = 0 (if I set SYSCLKDIVSEL = 1 the SW does run), the same SW does run out of RAM , as I wrote Yesterday: "I run the same SW out of RAM with SYSCLKDIVSEL 0 or 1 without any issue, however if I initialize SYSCLKDIVSEL = 0 to make ePWM frequency = 100MHz then the SW does not run out of FLASH.

    So that error dialog appears when you run the program that is loaded to Flash, or when trying to connect/load the program? I'm not sure why the SYSCLKDIVSEL value would impact that, but the C2000 device experts might have some additional thoughts on that. You could try posting to the C2000 device forum to check if they have any comments on this.
