    Hello,

    Here is my modified version of OSPI hardware with pi zero, what a perfect match!
    Thanks to Ray and Samer for such a great job to create this site and OpenSprinkler OpenSource project.

    Hi,

    Nice job. Did you need to modify anything on the OSPI hardware to be compatible with Pi Zero?
    I hardly wait Pi Zero to be available for ordering.

    Hello Sakos,
    Thanks, and no modification at all, smooth easy set up just like other raspberry pi. That’s the beauty of this little guy is being 100% compatible for Raspbian OS and all GPIO operation. All I needed to get a micro USB B adapter for the WiFi dongle. like this one:

    I know it’s very hard to get Pi Zero, I was lucky that just before Holiday season, our local MicroCenter carried a whole bunch of them, and they are all sold out again.

    @akobari: thanks for sharing. You are ahead of me for trying this out. I just blogged about my RPi Zero and OpenSprinkler Pi yesterday:

    Today, I received my Pi Zero. As a first test I moved the preconfigured and working SD card from my old RPi2 to RPi Zero together with the Wifi dongle. Unfortunately it does not work. The device is not accessible 🙁

    Hi sakos,

    By saying RPi2 If you mean Raspberry Pi 2, then you need Raspberry Pi Model A+ setup, PI zero SOC and GPIO is the same as Raspberry Pi Model A+, You can confirm this with Ray to be sure you have the correct setup.

    Good Luck,

    I know that Pi Zero has the same platform as Pi Model A+ and differs from Pi 2. However I could not see anny difference in OSPI setup for Pi Model A and Pi 2. There is a single SD card image and I cannot recall any platform specific configuration steps. I considered the OSPI FW as uniform for any Raspberry.
    Did I miss something?

    I downloaded the original OSPI image again and write on an SD card and inserted into Pi Zero. Unfortunately I got the same result. The green LED is blinking but nothing else happens. I mean that nothing appears on the HDMI output.

    Sakos, I have taken the SD card and WiFi dongle from my RP2 to get a new Pi Zero up and running without problem. I would note that the RP2 installation was a very recent build from the latest NOOBs and OS github. As such it was based on Jessie version of Debian.

    Following was from Adafruit site (https://learn.adafruit.com/introducing-the-raspberry-pi-zero/setting-up-your-sd-card):

    Raspbian Wheezy 5-15 or earlier do not support the Zero! Try Jessie instead

    Hope that helps, Pete

    Hi Peter,

    Thanks for your response. Yes, it is an option to start from scratch and install the OS then add everything which is needed for OSPI.

    On the other hand I still hope that someone can help why the Ray’s preconfigured OSPI SD card image will not work on Zero (and presumably on Model A/B) Raspberry Pis.

    As I mentioned in my blog post and the video:
    https://opensprinkler.com/raspberry-pi-zero-works-with-opensprinkler-pi/
    the pre-configured SD card image was made using an older Raspbian image (obviously long before zero came out) which does not boot on RPi zero. We will need to update the SD card image soon. But in the meantime, it’s much easer to just install the firmware yourself: it’s just three lines of command:
