Bootloader and debug of application

[Fabien Comte]

Hello,

When i have a bootloader installed and i try to debug application, it doesn't start application probably because debugger programmed application without the right headers. Is there any way to detect that a SWD probe is connected to bypass header checking ?

Hello,

The bootloader will go into DFU mode on startup if the "app valid" flag isn't set. This flag will be set when doing bootloader DFU, but has to be done manually when using a programmer. Please have a look at answer 'E' in this FAQ for more details.

Thank you it works.
