c6713 bootloader Issue

anwar naseem

I have used a bootloader available for BlinkDSK6713 for my custom board having c6713 and SST flash.

I have checked via using load symbols and breakpoint in .asm. But bootloader is not working. Values are not transferred into respective registers. (pic attached)

FLASH_START .equ 0x90000400 ;flash start address
CODE_START .equ 0x00000400 ;start of non boot code
CODE_SIZE .equ 0x0000F000 ;application code size in byte

The loop doesnot iterates..

Any comments/suggestions....

Salamat,

Obviously you can see the op-code at each location do not correspond to the intended source, which means your code is not loaded, and the IRAM is full of POR random stuff, hence the CPU is executing error-ed code.

You need to clarify that your boot mode is correct when releasing the CPU from reset and that your FLASH do contain your programming and is in data read mode when released from reset.

Good Luck,
