Debugging and UART-to-USB Communiction
The XMC4700/XMC4800 Relax Kit Series-V1 supports debugging via 2 different channels:
•
On-board debug probe
•
10-pin Cortex
™
Debug Connector (not assembled)
2.5.1
On-board Debug Probe
The on-board debug probe supports Serial Wire Debug (SWD) and UART communication. Both require the
installation of Segger’s J-Link Driver which is part of the DAVE
™
installation. DAVE
™
is a highly efficient
development platform for the XMC
™
microcontroller families to simplify and shorten SW development. It
can be downloaded at
. The latest Segger J-Link Driver can be downloaded at

shows the pin assignment of the XMC4700/XMC4800 used for
debugging and UART communication.
