Dear Sirs
As with the related post, "application does not start without debugger active", my code won't run upon power reset. Please see configuration below.

I'm not running a bootloader. I noticed the BEGIN: origin starts at 0x080000. I would have thought it should start at 0x000000. I've tried the 280045_FLASH_lnk.cmd file but have linker errors saying that the code won't fit in the memory. I've noticed that the Variant and core: setting is TMS320F280049C. The drop down is grayed out so I can't change it. As you can see, the uC has been switched to TMC320F280045_56RSH. Will this have any effect on the memory mapping? Please help. Thank you.
