TMS320F28069M: The microcontroller does not respond to firmware

Part Number: TMS320F28069M
Other Parts Discussed in Thread: MOTORWARE

Hi there, 

We have a custom-made board that would control two BLDC motors through DRV8300NRGER. The board is running on a TMS320F28069MPZT microcontroller. We were able to successfully compile and run the lab project proj_lab01 (LED toggling) from TI's MotorWare (v18) on the launchpad with the same microcontroller (LAUNCHXL_F28069M). However, although the project compiles and loads onto the custom-made board, the LED toggling pin on the custom board doesn't toggle but stays high. Moreover, when we step into the lines via a breakpoint, we can see that the pin is being toggled - it only stops toggling when the project is being resumed. If the debugging session is paused, there is an extra window that pops up with the following information "Break at address "0x3ff787" with no debug information available, or outside of program code.

The CCS version used is 12.50. The compiler's version is TI v22.6.1.LTS. The linker command line is F28069M_ram_lnk.cmd. We are loading the project through a third-party XDS100v3 debug probe. We have also verified the supply voltages, and they are all within the allowed tolerances. Please see attached the zipped project which we used during the session.


Thank you.

Best regards,
