Thank you for bringing this to our attention, I will work with the appropriate team to fix the documentation.
With the Aero compute board, you can access CPU_GPIO_01, CPU_GPIO_03, and CPU_GPIO_04 from the "J1" Power board port on the 80-pin accessories connector. The CPU_GPIOs can be set by exporting the gpio486, gpio481, gpio487 on the Linux consoles with the following commands:
echo 481 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio481 /direction
echo 1 > /sys/class/gpio/gpio481 /value
echo 0 > /sys/class/gpio/gpio481 /value
Hope this helps.
No, thank you. I just thought Intel should know that their documentation doesn't appear to match the hardware. BTW, we also noticed that after updating the BIOS using a soft reboot, the aero-get-version.py utility reports the new BIOS version, but the BIOS doesn't really seem to take effect until the next power cycle of the board (i.e., the CPU GPIO fixed by the 01.00.16 BIOS update don't become available until after a hard reboot).
