ARM-USB-TINY and SWD STM32F0

[mangokid]

I am currently trying to use the ARM-USB-TINY and the ARM-JTAG-SWD adapter to program some STM32 chips. In particular the F0, F1, and F4. The STM32F1 and F4 work fine with openocd when using JTAG. When i try and use SWD to program the STM32F0 or other variants it gets stuck on 'init'. I have used this hardware setup to program lpc11xx without any issues before. I have started spending time getting a better understanding of scripts in openocd to resolve this issue but at the moment I'm stuck.

*If i use the SWD interface from the STM Nucleo or Discovery boards it works fine with openocd.

Thanks all

In case you get no detailed help here, the OOCD folk are where I'd ask.

Yeah i figured as much. I wanted to ask here in case it was was something about the JTAG-SWD hardware.
