Serial Wire Debug is a new two-wire JTAG debugging protocol used by several low pin-count LPC and STM32 ARM chips. Adaptation of SWD by open source debuggers like OpenOCD has been slow.
Bingo succeeded in adapting the open source Versaloon firmware to do SWD programming on the cheap STM8S-Discovery and STM32VL-Discovery boards. Congratulations! We hope this is just the beginning of better SWD support in open source JTAG apps.

I’ve been trying to use it under OSX for 3 nights now.. and still no luck :) But I am not giving up yet.. this might be OSX 10.7.x fault… as it seems to have some problems with libusb and device access permissions. Although I started it under Linux ( VMWare ) it then detected fine with vsprog -L, but still unable to connect to any target :/
