Preparing the board for trace collection

The Trace Collector 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.
   • To program the firmware with nRF Connect Programmer, follow the instructions in Programming applications on nRF9160 DK.
   • To program from the command line, open a terminal window in the directory that contains the downloaded firmware and enter the following command (replace filename.hex with the file name of the downloaded firmware image):

      nrfjprog --program filename.hex --sectorerase -f NRF52 -r --verify

     Note: The nrfjprog tool, which is part of the nRF Command Line Tools, must be installed and in the path.
