I have a NXP EVM board with following setup.


- NXP PN7362 WLC Poller V3 EVM Board (L102379)

- NXP LPC-Linkn2 debug probe (OM13054)

- Keil uVision 5.22

- reference code

I confirmed that reference code runs on EVM without any problem.


Now I want to print debug message in Debug Viewer using printf function. But failed to search the correct guide for this issue.

Only I found manual page using ITM port at


But as far as I know, ITM port supports at Arm Cortex-M3 or over and PN7362 is Coretex-M0 core.


Is there any recommanded procedure or reference page for printf output ?
