TMS320F280039C: SysCtl_delay(23U) call from SysCtl_setClock(uint32_t config) blows up in developer board program.

Part Number: TMS320F280039C

I am getting started with debugging my application and when my application calls SysCtl_setClock(DEVICE_SETCLOCK_CFG); it blows up on when trying to call SysCtl_delay(23U).

If I set a breakpoint on SysCtl_delay and hover over it, it shows the following:

What am I doing wrong?

Thanks,

Chris,

Error information provided isn't enough to provide any useful debug tip.

Did you try assembly single stepping when you reached the SysCtl_delay(23U) code? Check were code execution is going wrong when you single step through the code?

Regards,

Manoj

I did and the error occurred when I tried to step into the SysCtl_delay function.

In any case my colleague Derek Cook helped me figure it out. I had to make the following changes to the 28003x_generic_ram_lnk.cmd file. The updated values are on the left.
