Preparing the board for trace collection

The nRF Util requires a current version of the board controller firmware to be programmed on the nRF52840 System on Chip (SoC) of the nRF9160 DK.

Complete the following steps to program the board controller firmware:

1. Set the switch that configures which chip to program to the nRF52 position.
   This switch is labeled PROG/DEBUG (SW10 on nRF9160 DK v0.15.0 and later, SW5 on earlier versions).
2. Connect your device to the computer with a Universal Serial Bus (USB) cable and power it on or reset it if it is already connected.
3. Program the downloaded firmware to your device.
   • Using nRF Util device, program the downloaded firmware to your device.
