Pi Zero status LED meaning

Sat Jun 16, 2018 5:46 am

What does the green LED on the PI Zero W mean exactly? I want to find out its different modes to help troubleshooting.

I'm trying to berryboot, and nothing is happening. No HDMI output and no green LED. I'm wondering if the SD card reader pins are bad. Should the green LED turn on if you boot without an SD card?
This Pi was working yesterday with MotionEyeOS, then I wiped the SD card to try berryboot and raspbian.

On the pi zero W the green LED indicates SD card access just like any pi, if there is no SD card in the slot then there is no LED lit.

if you read the not booting sticky posting.php?mode=reply&f=28&t=216095 you will find the flash codes in there to help diagnose any problems with the SD card.

I've changed the option on both of my Zeros with

Code: Select all

dtparam=act_led_activelow=on
in /boot/config.txt that makes it work like the normal activity light on my other Raspberries.

The options for setting the LEDs are documented in /boot/overlays/README.
