Several debuggers can be used to program and debug the EigerDB Zero+ development board. To enable proper connection of these debuggers special cable adapter boards are needed. As an example, the Keil ULINK2 default output connection is 20-pin JTAG flat cable with 2.54 mm spacing (ARM 7/9), but newer development boards have Cortex 10-pin SWD with 1.27 mm spacing between pins.
