Hello,

Have you looked into your .icf file for the project? (should be in the project directory in Windows Explorer). Also, you might want to look into overriding the default .board file and putting in your own flash memory address in the project options -> debugger -> download.

Here is a link to another user on the forum that had an issue that is related. He had success by modifying the .icf file:

Hope this helps.
