Unable to set adapter speed [Solved]
Hello guys,
I have a custom board with stm32f107vct7 processor. I’m trying to debug simple code with ST-Link-V2 bought on Aliexpress under Ubuntu 16.04. Then i’m trying to run project sw4stm32 throws next exception:
Open On-Chip Debugger 0.10.0-dev-00278-ga53935e-dirty (2017-05-09-09:16)

Seems like, openOCD sets higher adapter speed then it’s possible. Board worked fine under Windows7 on keil ide with st-link frequency 1MHz.
How do I go about requesting it connect at a lower speed?
Best regards,
Alex
