Hi Mike, It would depend on what you want to achieve. If you only need JTAG/SWD, then there are several open-HW implementation with FTDI already supported by OpenOCD, e.g. https://github.com/diegoherranz/steppenprobe But if you have other ideas, like electrical isolation PC-board, or ethernet connection ... then you could consider a new project. There is also available CMSIS-DAP firmware from ARM, under Apache-2.0 license. It can be ported on several MCUs. Personally I would be interested in implementing a high-speed trace port adapter for ARM targets, but I'm afraid of the missing skills (on my side) on the high-speed PCB and cabling. Antonio
