Hi,

 

I inadvertently flashed the wrong application image into the MCU. I used JFLASH(segger) to erase the part which it confirmed it did. Now when trying to load into RAM, I get the device is secure message and not ure how to get around it. IT will not let me access the part.

 

I get the following message. Looks like the security is programmed to not allow access. Docs say to try backdoor key but not really sure how to do that. Thoughts? Thanks.
