3.6.2 Debug UART
The ATSAMA5D27-WLSOM1-EK1 board has a dedicated serial port for debugging, which is accessible through the
6-pin male header J26. Various interfaces can be used as a USB/Serial DBGU port bridge, such as FTDI TTL-232R
USB to TTL serial cable or basic breakout board for the RS232/USB converter.
