Debbug to I/O Terminal of IAR will show wrong numbers ; String is OK

[Armin-Ka]

Hello,
i try to Debbug with the SmartRF04B Programmer/Debugger in IAR I/O Terminal. The Source is allready Prepared for this possibility.
I will See the published Strings,which will be OK. But if there are Numbers they will be wrong:
e.g. in File zcl_app.c Function zclApp_ReadSensors

LREP("currentSensorsReadingPhase %d\r\n", currentSensorsReadingPhase);  ---> will show: currentSensorsReadingPhase 1233

I add a Line after the Above One
printf("currentSensorsReadingPhase %d \r\n",currentSensorsReadingPhase); ----> will show: currentSensorsReadingPhase 0

I do not understand this issue. Please Help.
Thanks in advance
Armin
