Specifications

For devices such as the complex programmable logic device (CPLD) or field programmable gate arrays
(FPGA), gpiotool accesses those devices to drive the GPIO lines using the standard bus interfaces such as
i2c, mem, or pci.
CLI Options
./gpiotool - GPIO Tool
version 2.0
admin, 2014-10-01, bamboo-build-num
Syntax: ./gpiotool <option>
--h := show this help
--list := list available gpio chips and pins
--set [--chip=chip] --pin=pin# --val=value := set GPIO pin
--get [--chip=chip] --pin=pin# := get GPIO pin value
• list — lists all the GPIO pins.
• set — sets the value of the GPIO pin.
• get — returns the value of the GPIO pin.
