Hi, I’m trying to recall but I think the LED on my PiZero 2w used to flash based on SD card activity. I noticed that now it just flashes on a regular cadence, on, off, on, off. I’m sure I must have done something, and I’m aware of DietPi-LED_control. My question is what exactly is the meaning of the options under DietPi-LED_control. I have
1: ACT [actpwr]
2: default-on [default-on]
3: mmc0 [mmc0]
From the manual, which is located here: User Manual – Google Drive page 49, explains the leds and how to control them.
Not sure if there are specific dietpi opinions to control LEDs or if this is a function controlled by the bios file.
indicates that the device is powered on
static on
normally shows the activities of the eMMC (but does not work in all cases)
The easiest way is to play around with the settings and see which one suits you best. Our LED tool actually does nothing more than create udev rules. Theoretically, you can also do this manually.
