As per
https://github.com/recalbox/recalbox-os/wiki/Add-a-start-stop-button-to-your-recalbox-(EN)
Got this running fine on a RPi. However, can't get this working at all on the XU4.

Have enabled

system.power.switch=PIN56PUSH   

in recalbox.conf

I'm using a shifter shield as per here:

My understanding is that if I bridge the following pin with GND this will cause a power on/off:

WiringPi# = 9
Name = SCL1
GPIO# = 210

I've measured the resting voltage between these two and it reads either 3.3V or 5V as per the shifter shield setting. However, if I bridge it at either voltage, nothing happens!

Any ideas? Has the XU4 image had wiring pi and/or compatible scripts installed?
