We have implemented a serial wire debug port (2-pin SWD) in our ASIC, but do not provide access to the DAP via a standard JTAG interface. We have a test setup expects to connect via a classic JTAG interface. Is there a solution that would convert the 4-pin JTAG interface to the serial wire protocol external to the ASIC?

Thanks Stuart.
We are looking into using this:

along with
https://www.olimex.com/Products/ARM/JTAG/ARM-JTAG-SWD/
and hope it would work.

Hi,
Those devices look very interesting, especially the ARM-JTAG-SWD device.
I would be very interested to hear how you get on with these devices if you decide to go ahead and use them.
Thanks,
Stuart
