CF3 WP85 GPIO doesn't work


Hello everyone,

I have a mangoh red wp8545 and I tried to test GPIOs.
In the Raspberry Pi Rev B-compatible Connector (26 pins), I wanted to see the output of the GPIO 22 (pin 15 I assumed) with a simple LED.
I’ve configured correctly the Gpio through the terminal (ssh connection): export, direction and value.
Since I changed the value of the Gpio22 to 1, The LED is still off.
