ITM Trace by GDB + OpenOCD

I debug my C programs in Eclipse + GDB + OpenOCD by ST-Link/V2 (SWD), it works good.

In my programs printf retargeted to ITM_SendChar (Instrumentation Trace Macrocell), and I can see debug strings (printf) in Serial Wire Viewer in ST-Link Utility, but I can't see it in Debug console in eclipse + OpenOCD.

What should I do to see it in eclipse?

#openocd

ok. I 

launched STLink GDB Server (st-util), connected gdb to 4242, but cant see ITM trace strings.

It doesn't work!

texane/stlink with SWV does work. I have used it successfully.

Anyway, OpenOCD 8.0 (rc2) also works with SWV. With St-link/V2 from Discoveries.

It logs captured data to a file (I do not know how to push it to a console).

Tested with STM32L-Discovery.
