PI Zero 8 green LED flash sequence

[readlee]

So I was lucky to get the very last Pi Zero from my local shop on the front of MagPi However, as a quick test, using my old PI B+2's SD card.. I just get an 8 cycled green led flash. Reading the troubleshooting guide, this means it cannot read the files on (or) the SD. I know the SD card works and a bit more research suggests, to reuse old SD cards already set up for an earlier PI to follow ModMyPi page to update partition #1 & partition #5?

Where do I find this update process, plus, if I update my old SD. Will it still work in my old PI's?

I went all through the MagPi and for us, but not found the guide. I'll feel really silly if it is right under my nose, but just didn't see it.

I guess update the Raspbian on your SD card in your older Pi with apt-get update + upgrade the usual way to get a recent firmware.

You need to update Raspbian on any RPi except Zero or CM, it will then be backward compatible as well as supporting Zero


If you used NOOBS I have no idea what needs to be updated but this is how it was done previously http://thepihut.com/blogs/raspberry-pi- ... berry-pi-2


The following is for a non NOOBS standalone Raspbian

Jessie version:

Code: Select all

sudo apt-get update
sudo apt-get dist-upgrade
sudo reboot

Wheezy version:

Code: Select all

sudo apt-get update
sudo apt-get dist-upgrade
sudo reboot

+

Code: Select all

sudo rpi-update

Confusing answer?

Except Zero? Its a normal Raspbian, so the normal updates are applicable.

Code: Select all

sudo rpi-update

Bad advice? I have read over and over last year: Dont use rpi-update unless you are testing the bleeding edge of new versions.

You need to undertake the update to get latest firmware / kernel before using in ZERO


You keep stating Raspbian, that is confusing it is either Raspbian Wheezy or Raspbian Jessie, please actually state what Version, thank you


ONLY with Raspbian Wheezy to get the latest firmware / kernel is to use rpi-update as of the 24th November 2015

Bear in mind if you are using NOOBS Installer / Chooser the update procedure may be different.......

Sometimes rpi-update is necessary like in this situation.

In general you shouldn't do a rpi-update except if a forum member who knows what they're doing tells you to do it.
