Hi Rajamurugan, [quote userid="515467" url="~/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1471099/tms320f28379s-issue-with-serial-flash-programming-using-sci-bootloader-example-from-c2000ware/5743806#5743806"]When booting from flash it's working good.[/quote] Please specify address 0x80000 when you command the kernel to execute 6-Run . In general, you'll need to branch to the application's codestart, which is why boot to flash works and the serial flash programmer does not.

Then, you can verify the contents of the flash by loading the application's .out, and confirm that the kernel successfully programmed the flash. Best, Matt
