Whereupon I landed at IBDAP<\/a>. Someone had taken the same journey and decided to market a board and GCC\/makefile-compatible open source firmware, using the CMSIS-DAP standard that is itself an open product of ARM. Very cool. The only downside being that Armstart is sorta out of business. I ordered what may be the last IBDAP board they sell, because after I bought it, everything on their site was marked as sold out. It took a bit of (email) arm-twisting to get them to ship me the board. But, it arrived, I was able to build the firmware (flashing it using another SWD interface), and I’ve connected to a couple boards through it with apparent ease. I may have finally now reached a point in my journey where I can release my obsession with open SWD.<\/p>\n The board may be found at other places, like Adafruit<\/a>.<\/p>\n In case the Github link disappears, here’s an IBDAP fork<\/a>. Here’s the firmware I built<\/a> most recently, as a check for your build\/board.
