TMS320F28379D: Code doesn´t start after flashing

Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE

Hello there,

i have created a project for the TMS320F23879D on the LaunchXL board from scratch using
CCS Version 6.2.0.00050
by
FILE > NEW > CCS Project > Empty Project
and the application dosen´t start after flashing.
Earlier it did, and i never changed the positions of the boot select pins of the LaunchPad.
By earlier i mean that after a vacation i had to set up CCS freshly, since to some automatic network maintance it didn´t work anymore.

It runs when i use debugging and i see CCS writes the code to flash, but when i exit the debug modus and reset the device power on-off or the
reset button, ths application doesn´t start.

I read in the manual about the Z1 and Z2 zones in the DCSM area. I "screenshoted" the content, see below.
Does someone have hint, why the application doesn´t start?

PS.: i had an earlier thread, and i was told to shift this topic to this forum
e2e.ti.com/.../636742

Best regards!!

    I don't think there is a problem with DSCM. You mentioned that you started a project from scratch, it is hard for me from your message to tell what you tried before when it was working and what changed.

    So I'm suggesting below, if you already tried below let me know.

    I would suggest you to start with a TI example (for ex: a blinky - C:\ti\c2000\C2000Ware_1_00_02_00\device_support\f2837xd\examples\cpu1\blinky). Check the build configurations supported for the example and depending on the HW platform you have you choose the launch pad configurations if needed.

    build both the RAM and flash build configurations. The Flash build configuration should work with out the debugger after you program the application using CCS.

    Now check the boot ROM chapter of the device TRM, the device boot mode pins should be set to boot to flash and when you power up the device, the application in flash should run.

    Once you get it working with the TI example, then try same with your project.

    Hope this helps.

    Best Regards
