TMS320F280049C: TIDM-DC-DC-BUCK example does not run from FLASH memory

Part Number: TMS320F280049C
Other Parts Discussed in Thread: TIDM-DC-DC-BUCK

Hello,

the TIDM-DC-DC-BUCK example for F280049C works very well when launched from debugger. However, it does not seem to start once the microcontroller is reset. 

Judging from the attached linker file (f28004x_flash_lnk.cmd) and compiler predefined symbols ("_FLASH") example should run from flash.

The memory at 0x80000 contains ITRAP1 instruction rather than jump to _c_int00

If I reset the microcontroller using debugger and then manually set the PC register to 0x82dcb, code seems to work normally.

The BOOT pins on the development board are set correctly as I can program a simple blinker example and run it from FLASH without any problems.

Could you suggest a solution to launch the DCDC buck example firmware from FLASH memory?
