Probably explains why no such device exists.
JTAG SWD to RS232 serial?
Is there a hardware device that will enable a simple dumb terminal program via RS232 (eg Windows Terminal, TerraTerm etc) to connect to a JTAG SWD interface? Or even better, a TTL level serial interface to JTAG SWD, so that a dumb terminal can connect & debug?
I've seen some devices that are a combined USB>JTAG and USB>RS232, but don't think they extend the functionality to JTAG>RS232.

this may help
might be better as it supplies the only comment/answer as Hinekadon's link lists the question only.
Thanks for the replies. Looks like this isn't going to be as simple as I'd hoped. Trying to 'glitch' my way past the read out protection on an embedded MCU via it's SWD interface. The glitching software reacts to simple serial inputs to check if the glitch was successful or not. Hence the request to interface SWD to serial. Wonder if I can get a little Arduino board or similar to do this?
what cpu ?.
