flashrom
To update or erase the BIOS flash memory, the smbiostool uses flashrom.
gpiotool
The gpiotool controls the state of the GPIO lines from the CPU or any other device that drives the GPIO lines.
The CPU GPIO lines the map in Linux to /sys/class/gpio entries, which are manipulated through the standard read/write
interfaces. There is chip numbering to support multiple GPIO chips, or chips at an offset. 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

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.
