I want to debug an application using J-Trace Pro from Segger and Ozone. I am using the nRF 5340 DK.
I used samples/basic/blinky project as a starting point from nRF Connect SDK v2.0.0, compiled with VScode.
I did the following modifications:
- Added CONFIG_NRF_TRACE_PORT=y in prj.conf file:
CONFIG_GPIO=y CONFIG_NRF_TRACE_PORT=y
- Removed from nrf5340_cpuapp_common.dts button3, button4 and the flow control pins for the uart port to avoid conflicts with TRACEDATA pins

- Turned off the UART flow control using the switch SW7 from the nRF5340 DK.
- Debug with Ozone, and configured the Trace Settings
- After running the program the Instruction Trace view displays No data
When using Nordic_nRF5340_APP_TracePins.zip sample project from Segger the Instruction Trace work properly.
What other modifications should I do in order to be able to debug an application generated by the VScode, using Instruction Trace.
