I would like to use printf using ITM for debugging my application using a BL652 module (nRf52832).
I have followed the instructions in the Keil paper APNT_308. Printf is working fine when I execute the code on the PCA10040 board, but when I connect my target HW to the Debug Out connector the printf does not work. I can execute code and debug on the target, but the ITM will not work. There is signal on the P0-18 when measuring on the connector, but no message in the Debug (printf) Viewer.
Can any give a hint where to look for the bug?
