This is a linux driver for LED status lights of the TerraMaster F4-220. It was created looking at the binary of the driver module from TerraMaster. I later found there is now a GPL source version provided by TerraMaster at https://www.terra-master.com/code/led_drv_1800.c .
Originaly forked from https://github.com/stroyan/led-drv-f4-220. Great work from, Mike Stroyan mike@stroyan.net Mon, 13 Jan 2020 15:10:29 -0700
Modified by me for it to wotk with OpenMediaVault 5, and latest kernel (5.6) -- Joao Amaro joao.amaro@gmail.com Sun, 19 Jul 2020 18:39:47
This is a kernel module. It allows to change the colors of the front leds on Terramaster F4-220. It creates a char device in /dev/leds that you can write into it, and change de colors of the LEDS. They do not track the current usage of the disks (maybe in the future, who knows :) )
For the hard drives leds you can change the colors to: Green, Yellow, Red For the LAN led you can change the colors to Green.
Download this repo to your terramaster, and compile That's it.
