Blinky sample in custom board and nrf52840DK

Hello,

The dongle is a special case, because it comes pre-programmed with a bootloader from the nRF5 SDK. Are you sure you have programmed this exact bootloader to your custom dongle?

If you have a custom board, and a programmer to program it, I suggest that you treat it like a DK, except you configure the board file to match your board layout, but keep the nRF52 dongle out of the equation, because the assumed pre-programmed bootloader may not work in your favour.

For details on the nRF52 Dongle, please see this guide:

Best regards,

I've tried to flash from Visual Studio too, and the result is the same. My question is:

If I have 2 boards, 1 nrf52840DK and 1 nrf52840dongle (is a custom board, but is has the same configuration than a dongle), Why the blinky sample work on my nrf52840DK (if I select that board in build configuration) but it doesnt work in my "dongle" board (if I select nrf52840dongle in build configuration)

I build the .hex with the button "build" of visual studio code and flash my board with "SEGGER JFlash lite". I flash it with a JLink base programmer and after it I connect my board via USB.

Hello,

When you flash your board, how do you connect your board to your computer, and how do you program it? Do you use the flash button in Visual Studio Code?

Probably just because nobody made it, and we don't have a tested version to include in the SDK.
