Hi,

Did you follow the note for nRF52840 while generating the bootloader setting as the following?

Note: For nRF52840, you use --family NRF52840.
--family: Device family, match with your chip. If you have nRF52840 you have to use NRF52840 instead of NRF52.

[quote user=""]what's difference between flashing on IDE and nRFgo?[/quote]

As mentioned here and here, nRFgo Studio is outdated and we are not working on the app anymore. Does it work to program the bootloader with nRF Connect for desktop and the programmer app?
