Hello

I am using NUCLEO L053R8 (STM32L0) and Keil uVision 5.15 and ST-Link (embedded in the nucleus board). I buid a FW program using CubeFx

I am setting up the stdoutput with no semihosting using the ITM.

First I cannot find the Debug printf window in the uVision GUI claimed by the Keil documentation at http://www.keil.com/support/man/docs/ulink2/ulink2_trace_itm_viewer.htm

I understand this is for keil U-LINK2 though. Does ST link support ITM debug?

I would use CMSIS ITM functions I cannot find the functions ITM_SendChar etc. as documented by https://www.keil.com/pack/doc/CMSIS/Core/html/group___i_t_m___debug__gr.html#gaaa7c716331f74d644bf6bf25cd3392d1 (I see CMISIS stff in the CubeFx generated program

)

I am afraid I am doing something undamentally wrong ...

I am afraid I am doing something fundamentally wrong ...

The Cortex-M0 doesn't support the ITM/SWV mechanism. For the Nucleo use the USART2 connectivity via the ST-LINK's VCP, and then use a terminal program to connect to that COM port.
