9 USB to Serial Interface
The EVB incorporates an interface providing a serial connectivity via a direct USB connection between the PC and the EVB. The circuit
contains an FTDI FT2232D USB to Serial interface which should automatically install the drivers for 2 additional COM ports on your PC.
Note that only one of these is used so you will need to try both. For more information on the USB drivers and general fault finding, consult
the FTDI website at

– USB to Serial Interface
The PTC27 MCU port (
LPUART13_TX
) and PTC26 MCU port (
LPUART13_RX
) signals are routed to the FTDI transceiver via zero ohms
resistors allowing the transceiver to be isolated from the MCU pin if desired. The default configuration is with the zero ohms resistors,
routing the TX and RX signals from the MCU to the FTDI transceiver.
38-Pin ARM
ETM Mictor
Connector
P1
The Mictor (Matched Impedance Connector) has been the
standard way to connect a trace probe to an ARM target. It
supports up to 32-bit ETM trace and is really intended for
use with very high-speed ARM processors such as Cortex-
R4 and Cortex-A9. Cortex-M7 supports 16-bit data trace
using the Mictor connector. This is only available with DS-5
using a DSTREAM debug and trace unit.
20-Pin ARM
Standard
JTAG
Connector
J365
The ARM standard JTAG connector has been used for
many years in systems with ARM processors.
It supports the JTAG interface for accessing ARM7 and
ARM9 based devices. For Cortex-Mx devices, it supports
Serial Wire and JTAG interfaces for accessing all SWD,
SWV, and JTAG signals available on a Cortex-Mx device.
The header (e.g. a Samtec: TST-110-01-L-D) is a 20-Pin,
0.10" (2.54 mm) pitch connector with these dimensions: 1.3"
x 0.365" (33 mm x 9.27mm).
