I have a Meraki MX100 that I have installed VyOS on. While otherwise perfectly functional, the one thing that I cannot seem to get working is the LED board on the front panel. I'm no developer which I'm sure is 99% of the issue here.

The LED's don't show up in /sys/class/leds/. I believe that the LED's are driven from a GPIO interface, but I don't know how to say "Hey Linux these are LED's". The Meraki MX100 is a proprietary design and information is hard to come by.

I'm including a picture of the back of the LED board. The header for the cable on the motherboard isn't notably labeled.

  • I'm not sure if this helps, but I was able to find the following entries from the make config build file in the Meraki kernel: CONFIG_KEYBOARD_GPIO_POLLED=y CONFIG_ARCH_WANT_OPTIONAL_GPIOLIB=y CONFIG_GPIOLIB=y CONFIG_GPIO_DEVRES=y CONFIG_GPIO_ACPI=y CONFIG_GPIOLIB_IRQCHIP=y CONFIG_GPIO_SYSFS=y CONFIG_GPIO_ICH=y CONFIG_GPIO_PCA953X=y CONFIG_GPIO_PCA953X_IRQ=y CONFIG_LEDS_GPIO=y – Ozzy S Mar 24 '19 at 16:03
