nRF52840 initial bootloader

[michel_93]

Hi,

We are currently develop our costum board with an nRF52840 SoC. Are the nRF52840 shipped with an initial bootloader to programm the device via USB? Because if possible would like to prevent to use programming interface via SWDL and SWCKL. Is there something like a checklist for first time programming a nRF52840?

Thank you

Hi Michel.

The nRF52840 SoC doesn't have a built-in USB bootloader.
The nRF52840 Dongle has a built-in USB bootloader.

To program the nRF52840 SoC you should take a look at the Getting Started Guide on the infocenter, under Nordic tools and downloads you need to select a development IDE which you will use (note that Segger Embedded Studio is free to use with Nordic products), and download the essential tools (a SDK, preferable SDK 15.2 and nRF5x Command Line Tools).

A Getting Started Guide for Keil and Segger Embedded Studio can be found here.
A Guide for Getting Started with our latest SDK (SDK 15.2) can be found here (Running precompiled examples, installing the SDK, and so on).

To program the nRF52840 Dongle, you can use the built-in USB bootloader, as explained here.

Hope this helps.
