Raspberry Pi 5 (bookworm) not working with OSPI?

[boz]

Hi,

My old raspberry 4 broke down and I upgraded to 5 and now it’s not working, I can’t open the valves.
Webpage is up and I login but not open any valves.
My OSPI board is v1.43 any ideas or suggestions on this matter?

Please follow the instructions here to update your firmware to the latest:
https://openthings.freshdesk.com/support/solutions/articles/5000631599-installing-and-updating-the-unified-firmware-on-ospi
Bookworm made breaking changes about how GPIOs are operated and we’ve updated the firmware to address that issue.

Thanks for the update but I did follow that link when I tried to install ospi for the first time.
I checked every suggestion, no 1wire support is enabled.
But still can’t enable the valves.

Is there something more that I can check to see if there is a conflict within GPIO interface?

Can you check if this file exists on your system:
/sys/class/gpio/gpiochip512

Basically the build script uses this file’s existence to check if it needs to link with the gpiod library (which is needed for gpio operations in bookworm):
https://github.com/OpenSprinkler/OpenSprinkler-Firmware/blob/master/build.sh#L41C11-L41C38

I forgot to mention: if you run
git log
in the firmware repository, what’s the first few lines that’s displayed?

Hi,

Yes that file exists on my system.

This is the log output:

Everything seems fine on the firmware side. Honestly, I don’t know. We currently don’t have a RPi 5 for testing. We did test the firmware under RPi 4 with Bookworm and the GPIOs are all working. Not sure if something is different with RPi 5. If you want you can send a support ticket at:
support.opensprinkler.com
and arrange to send us your RPi 5 so we can diagnose the issue and make sure it works then send it back to you.

Ok, I understand but sending my RSPI5 from Europe to US isn’t an option, unfortunately.

But why not start a crowdfunding page and I would gladly support that to get this excellent solution to be supported on RSPI5.

Going back to a 4 version with SD card isn’t an option either, had so much problems with corrupt SD Cards and now I can use the NVME disk is fantastic solution.

So please, how can I help so this can be supported and not be a discontinued project?

We’ve ordered a RPi 5 and will have it next week so we can test.

What I meant to say is that having your actual hardware at hand would allow us to make sure it’s working before sending it back to you. Chances are we will get our RPi 5, and the firmware will pass all tests, but then it doesn’t give us any information about why it doesn’t work on your end. It’s not that we can’t afford to buy an RPi 5, it’s pretty cheap and affordable, the issue is reproducibility: that if it works with our RPi 5, it won’t give us any information about why it doesn’t work for yours.

Excellent, the thing I can do is to restore my rspi4 to version bookworm, it worked fine before the SD crash. (2 weeks ago).
I will then wait on your findings.

FYI:
I’m using the NVMe base board.
https://shop.pimoroni.com/products/nvme-base?variant=41219587178579
with a Kingston KC3000 M.2 512GB SSD.

We got our RPi 5 today and found the issue. Basically RPi 5 has changed the gpio chip name. So this line:
https://github.com/OpenSprinkler/OpenSprinkler-Firmware/blob/master/gpio.cpp#L475
the name “gpiochip0” should be changed to “gpiochip4” on RPi 5. We will be working to address this and make the firmware compatible with all RPi versions. In the meantime, you can modify the name yourself and recompile the firmware, and see if this fixes the issue for you.

Excellent news, changed it and recompiled it, now it works again.
So happy!
Thanks for the effort and time!
