DAPLink (CMSIS-DAP) compatible hardware

Once you are ready to flash firmware to the DAPLink hardware, you can utilize the built-in NXP USB ROM Bootloader. A fresh piece of hardware should enumerate immediately into the bootloader when the USB is plugged in. Otherwise, you can hold down the pushbutton while plugging in the USB. The ROM Bootloader will enumerate as a MSD labeled .

To connect the Glasslink serial lines to your targets UART, please reference the 10pin ARM header pinout below. The current design assumes that you are creating your target hardware and have the ability to route your UART pins to the "unused" pins of the…
