The I/O module GPIO mapping and references will be provided as a separate technical sheet and article and will be released at the
support web portal for user/customer reference.
Edge Gateway I/O Module PCIe expansion mapping
Description: The PCIe slot on the external I/O module for the Edge Gateway are driven directly from the host PCIe bus. Since it is
generic PCIe expansion there are no PCIe device specific drivers integrated into the Wind River Linux OS image. If there are specific
PCIe card used on this slot, contact the vendor of that PCIe card to verify if they have Linux drivers and if that is a kernel mode
driver such driver may have to be ported to Wind River Linux OS environment which uses 3.14 Linux kernel version on the Wind River
Linux OS image shipped from the factory on the Gateway.
Edge Gateway Zigbee Module Functions
Description: The Edge Gateway supports a USB Zigbee dongle as an optional add-on hardware. When the Zigbee dongle is present
on the system it is enumerated to the OS as a USB device and accessed through cdc_acm kernel driver layer on the Wind River
Linux host. There are no native application software on the factory installed OS image to perform Zigbee protocol for this device. A
basic communication with the Zigbee module can be verified using minicom terminal interface application as well as to get basic
information from the Zigbee dongle.
For example: The following command would launch minicom with device /dev/ttyACM6 assuming the Zigbee dongle is enumerated
into /dev/ttyACM6 port.
root@WR-IDP-XXXX:~# minicom –D /dev/ttyACM6
The Screenshot below shows the response from the Zigbee dongle when the Zigbee USB dongle is enumerated under /dev/
ttyACM6 port.
•
Sending an AT command inside minicom session should return an OK from the device.
•
Sending an ATI command inside the minicom session should return the module information like "Telegesis ETRX 3588" etc.
