hi,
i'm using atmel studio 6.2, i have to program hex file in flash of sam4s directly in sam4s xplained pro board ,but start without debugging doesn't program properly,so i have to do only debugging(which is working fine).

See the SAM4S data sheet, section 8.1.4 Boot Strategies. Make sure your GPNVM bits are set correctly. Specifically, ensure GPNVM1 is *set* to boot from Flash. It is clear by default, which causes the SAM-BA boot ROM to execute out of reset.

 

Edit: Didn't notice the date on the first post. Other SoCs will probably have similar fuses. RTFM!
