With recent Linux kernels, the GPIO numbering scheme has changed. The documentation should be updated.

This is an example of how to find the correct GPIO to turn on target power on a Rasbperry Pi 4:

cat /sys/kernel/debug/gpio

echo 525 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio525/direction
echo 1 > /sys/class/gpio/gpio525/value
