TMS320F28P650SK: Error during Flash Programming

Other Parts Discussed in Thread: UNIFLASH

Hi,
I am getting the following error when trying to Flash Project in CCS Version: 20.4.1.4__1.10.1. I have been able to flash and debug my project for weeks. Then today I accidentally kill power to my device in the middle of flashing it. Now it is getting this error everytime I try to flash it.
I thought maybe it needed to be unlock and a total erase but I tried doing this using the Uniflash tool, not sure if I was doing the right thing, but everything I tried did not help.
I am able to flash a totally different device/board without any issues, it is just this device that is getting the error.
Any help will be greatly appreciated,
Rob

Here is a similar error message I get when trying to execute the Flash Project of my bootloader application in a different flash address range on the same device.

Thanks, Rob

Hello Robert,

Powering off the device during a flash operation can result in undefined behavior. It looks like you are trying to erase a sector that has protection masks enabled. Can you confirm that the Erase CMDWEPROT settings for the flash plugin are set to 0x0?

Additionally, is the device in flash boot mode? Can you try changing it to wait boot then erasing the flash?

Best,

Alex

Thanks Alex,

My Erase CMDWEPROT settings for the flash plugin were set to 0x0, but changing the Boot Mode to Wait Boot allowed me to erase and program the flash.
