STM32F4 ITM Trace without ST-Link

is it possible to get the usual "printf" outputs on the SWO pin without any Debugger(like ST-link) conected?

My goal is to connect a plain FTDI Uart2USB converter to the SWO pin. And just read the outputs.

If I do so and start debugging with the ST-Link I get all outputs through the FTDI, it works great.
But when I stop debug mode there are no messages at all.

(the reason why I'm not jsut using the ST-Link it self for SWO is, that the cheap ST-Links are not fast enough. I get several messages lost. Other Debugger (like UPROLINK2) are to expensive.)
