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
-
Solder the P25 connector on the nRF7002 DK.
-
Cut SB7 and short SB9 to use P0.06 as
an alternative control signal for BUCK_EN.
-
Modify the firmware to use P0.06 instead of P0.12 for
BUCK_EN and to enable P0.12 as TRACECLK.
-
Short the SB11, SB12, SB13, and
SB14 solder bridges.
-
Cut SB8.
This disables the onboard flash memory which shares the trace data
pins.
