nRF7002 DK v1.0.0

Tracing instructions

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

To use the tracing functionality on the nRF7002 DK, the following modifications to the Printed Circuit Board (PCB) are required. Refer to Debug input and trace connectors for more information.
Note: It is not possible to use the onboard flash while using trace
  1. Solder the P25 connector on the nRF7002 DK.
  2. Cut SB7 and short SB9 to use P0.06 as an alternative control signal for BUCK_EN.
  3. Modify the firmware to use P0.06 instead of P0.12 for BUCK_EN and to enable P0.12 as TRACECLK.
  4. Short the SB11, SB12, SB13, and 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.
