3.8.2.3 Debug Serial UART over USB J2102

The UART connection used on the HDK660 is a USB micro B connector (J2102). This debug

UART is available over USB via the FTDI FT232RQ chip on the carrier board. To get the

serial terminal working with a PC, user needs to ensure that the appropriate FTDI drivers are

installed.

This connector provides a JTAG interface to the main processor by which users can

connect a JTAG (Lauterbach / USB Wiggler) 20 pin ARM JTAG.

NOTE:

The development kit does not include software support for JTAG
