printf swo on stm32l0x1 m0+

Designing own board based on stm32L0x1 and looking at debug provision.

Am I right in thinking that printf style output is not available via the debugger ( ST-LINK/V2) on the stm32L0 (m0+) parts as:-


1) They only have SWDIO and SWCLK pins and don't have SWO pin.

2) They don't have ITM in debug unit.


I can track out usart lines and gnd to some pads and connect a usb to ttl cable for use with hyperterminal but was wondering are there any other options via the debugger ?
