GPIO

NOTE: For more information on GPIO sysfs interface, see https://www.kernel.org/doc/Documentation/gpio/sysfs.txt.

The GPIO connector (AD5593R) on the Edge Gateway 3001 has 8 pins. The connector can controlled by the standard Linux

GPIO.The GPIOs number maps 330 to 337.

1. Pin: GPIO1

2. Pin: GPIO8

3. ISO GND: Bottom row isolated grounds

Example 1 (as root): Set GPIO 1 as output, value as 1

$ echo 330 > /sys/class/gpio/export

$ echo out > /sys/class/gpio/gpio330/direction

$ echo 1 > /sys/class/gpio/gpio330/value

Example 2 (as root): Set GPIO 8 as input, and read value

$ echo 337 > /sys/class/gpio/export

$ echo out > /sys/class/gpio/gpio337/direction

$ cat /sys/class/gpio/gpio337/value

Example 3 (as root): Connect GPIO 1 to 8, read GPIO 8 pin value

$ cat /sys/class/gpio/gpio337/value

Security

Trusted Platform Module (TPM)

NOTE: For more information about the TPM, see https://developer.ubuntu.com/en/snappy/guides/security-whitepaper/.

TPM is only supported on devices that have TPM hardware installed on products with Snappy-enhanced security support. The

TPM on/off setting is configurable in the BIOS and manageable in the operating system.
