Any thoughts on this? The OpenOCD CMSIS-DAP debug interface relies on libUSB for its driver(s). The problem is that when these are installed much mbed functionality is lost, especially the ability to drag+drop new binaries onto the mbed drive to reflash the target board. The debug interface for CMSIS-DAP is documented and works directly via a standard USB HID driver. Are there any plans to use this interface rather than the OpenOCD variety? It would make set-up and problem diagnosis much simpler … TIA.
