Hello,
i´ve followed all tutorials/threads trying to send printf() to the Debug(Printf)Viewer but not luck untill now. i can see the corrects characters within the ITM Stimulus Port Register 0, so i guess my code is right (i paste it at the buttom of the message) I have also checked and SB10 solder bridge is made in my board.
i´m using ST-LINK/V2 for debbuging, and i also updated the trace setting in Options for target like that:
-> Core Clock to 72MHz -> Trace Enable checked -> ITM Stimulus Ports: www.keil.com/.../ulinkpro_trace_itm_viewer_port0_0.png
Where else should i look when Register are correctly updated but they are not showed in the Debug(Printf)Viewer?
