TS-7300 MANUAL
CONNECTORS AND HEADERS
5.4 USB Connector
The USB Connector on the
TS-7300
provide two USB interfaces for the user. These are
directly connected to the EP9302 processor, which integrates an USB dual-port Open
Host Controller Interface (Open HCI), providing full-speed serial communications ports at
a baud rate of 12 Mbits/sec. Up to 127 USB devices (printer, mouse, camera, keyboard,
etc.) and USB hubs can be connected to the USB host in the USB “tiered-star” topology.
This includes the following features:
✔
USB 2.0 compatible
✔
Open HCI Rev 1.0 compliant
✔
USB device connections support at both low-speed (1.5 Mbps) and full-speed (12
Mbps)
✔
Root HUB integrated with 2 downstream USB ports
✔
Transceiver buffers integrated, over-current protection on ports
✔
Supports power management
✔
Operates as a master on the bus
Note
TS-Kernel implements all the necessary driver support to enable the USB OHCI.
Also, a wide variety of USB drivers for devices such as mouse, keyboard and flash
memory are available. Refer to the Linux for TS-ARM User's Guide or contact us
for further information on how to integrate an USB device and an USB Linux driver
with your
TS-7300
.
5.5 SD Card Connector – CPLD
The SD Card socket (ALPS connector) at the back side of the
TS-7300
enables SD Cards
to be plugged to the SBC. The hardware core implemented by Technologic Systems is
integrated inside the on-board CPLD. Technologic Systems has written a binary Linux
driver module and a set of generic, OS-independent read/write routines for accessing the
SD flash inside of an ARM object (.o) file. The format of the SD card must be in EXT2
format for proper operation with Linux as a root file system.
5.6 SD Card Connector – FPGA
There is an second SD Card socket (ALPS connector) on the
TS-7300
. This is not
bootable and can be used as additional storage memory or for backup applications such
as RAID functions.
The hardware core that controls the operation of the second SD card is integrated on the
FPGA, therefore it will be only available if the appropriate FPGA core bitstream is loaded.
The default TS-BITSTREAM for TS-7300 includes support for the second SD Card. In
addition, Technologic Systems provides Linux drivers which enable reading and writing
operations.
The SD Card core on the FPGA is located at physical address is
0x7200_0020
