I have an up2 board (8 GB RAM, 64GB eMMC). I folow an exmaple described here https://wiki.up-community.org/Pinout_UP2#GPIO trying to blink one of bard's LEDs. However nothing blinks, what is the problem?

My Kernel version is: 4.15.0-29-generic
OS: Ubuntu

All patchs like /sys/class/gpio (the one from example) are there so I assumed the kernel is ok right?

In case the kernel is wrong, do you have any guide how to write module for this GPIO to control it?
