Using SWD to flash and also have DFU bootloader installed ?

[Roger Clark]

Is there a way that I can still flash via SWD, but also have the DFU bootloader installed ?

The moment, as soon as I install the DFU bootloader, I have to upload the app via DFU because the application CRC is not being set in the flash when I program it using SWD

I know I could modify the bootloader code and remove the CRC check, but I don't really want to do that. I'd prefer a method where I could generate a HEX file to flash via SWD that also updated the bit of flash that contains the CRC

Yes, this is possible, you just need to include the bootlaoder settings page. You can generate your own with nrfutil which will contain necessary information for the bootlaoder to validate your application. Instructions can be found here: infocenter.nordicsemi.com/.../nrfutil_settings_generate_display.html
