Buddy, A c6713 is designed to bootload from FLASH memory. There are some cases: 1. As usually,power on ,we can see the address space (0x00000000~0x000003ff).It should be filled by the data loaded from the FLASH. But the first 4 bytes( 0x00000000~0x00000003) are always filled by 0xFFFFFFFF . 2. In the case 1,if we reset the DSP by the CCS. Then ,the firt 4 bytes will reload the da...
