Re: [Openocd-development] SWD vs. SWIM

[simon q. <sim...@gm...>]

SWD is working in my branch of OpenOCD, but ONLY on Versaloon dongle.
Official OpenOCD will maybe add SWD support in 0.5 release.
FT2232H is USB-HS device, I don't think there is any chance for USB-FS STM32
Device to be faster.
But it's almost impossible for FT2232H to support SWIM.

If you want STM32_JTAG/SWD and STM8_SWIM support, check here:
www.simonqian.com/en/Versaloon, software/firmware/hardware are all available
there.
It can support JTAG/SWD in OpenOCD, and SWIM in vsprog(programming ONLY).
For STM32_JTAG, the fastest downloading speed I tested in vsprog is 35KB/s.
