Onboard debugger and UART connection

The Radar Baseboard MCU4 features an onboard debugger, which comes preloaded with licensed firmware for
debugging and communicating with the main radar MCU via the UART pins. The onboard debugger supports
two-pin SWD and UART communication. Both require the installation of SEGGER's J-Link driver, which is part of
the DAVE™ installation.
During installation of the J-Link driver make sure to select the option "Install USB Driver for J-Link-OB with
CDC", as shown in Figure 20.
