nRF7002 DK v0.7.2

Tracing instructions

nRF7002 DK supports Embedded Trace Macrocell (ETM) and Instrumentation Trace Macrocell (ITM) trace.

Refer to nRF7002 DK debug and trace headers for more information.

  1. Solder the P25 connector on the nRF7002 DK.
  2. Cut SB7 and connect a wire from the SB7 pad on nRF7002 side to VDD_MEAS (always high) or any GPIO.
    For example: P0.05 to control BUCKEN from the firmware.
  3. Modify the firmware to remove P0.12 from BUCKEN and enable it as TRACECLK.
  4. Short the SB11, SB12, SB13, SB14 solder bridges.
    These are the trace pins out of the nRF5340 System on Chip (SoC).
  5. Cut SB8.
    This disables the onboard flash memory which shares the trace data pins.
