TMS320F28377D: 28377 update

Hello Ding,

What are you expecting to see in at this location?

I want to generate bin file used to upgrade codes, but I found  some flash address is 0xffff, the bin file has not 0xffff, so using bin file to upgrade had failed. I expect that the bin file also has 0xffff as the same as the flash in chip ,my app address is 0x88000

My CCS version is 1260

I expect no 0xffff unused data on flash because my bin file has no 0xffff data

Hello Ding,

Does your bin file cover the entire Flash? Flash when erased has 0xFFFF values, so any address that is not specifically covered by a linker section would remain erased and have the 0xFFFF value. When performing verification, you need to either refer directly to your linker section address ranges, or you can provide a linker fill argument to the linker so that it knows what to put in those empty spaces.

The problem is done.I also had a jump question.. By the watchdog,App jump into bootloader, the code do not run.  Even device reboot by hardware, the code still do not run.when i connect the debugger, it appeared the picture

Hello Ding,

Please check the following:

• Boot mode select pins are configured for boot to Flash
• Code entry point is at the correct address for Flash boot

Best regards,
Ibukun
