Are you modifying a general project to be a bootloadable project (app1 for PSoC 6)?
If yes, please refer to the steps shown in AN213924 chapter 4.3: http://www.cypress.com/file/385706/download
If you still have any issue with referring to the steps, pls let me know at which step the issue occurs.
Thank you! I'll try those steps again and get back to you!
