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
0
Example 3 (as root): Connect GPIO 1 to 8, read GPIO 8 pin value
$ cat /sys/class/gpio/gpio337/value
1
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.
If TPM is turned off, the device node (/dev/tpm0) does not exist.
