flashburn

hello
My task is to convert a file.out to a  file.hex, my goal is to  program it with the flashburn tool of CCS, but the stage programming was interrupted  and an error message appears "hex file error: $ improper Axxx address field ", knowing that the code c Project  is  just a simple one  that test the dm642 dsp's LEDs  behaviour.
 The used tools :
-the command to do the conversion is: hex6x -a -o  led.hex  led.out
-ccs 2.21.00
-flashburn v 02.71
Thank you for your help
