LE 12 Nightly - RPI tools add-on issue

ghtester · May 26, 2023 at 12:59 AM

After upgrade from LE11 to LE12 nightly-20230522-794a8ad (RPi4.aarch64) Raspberry Pi Tools (Team LibreELEC - 11.0.0.0) is not working properly anymore and it looks there's no updated version yet.

Still the same issue after upgrade to LibreELEC-RPi4.aarch64-12.0-nightly-20230801-1c44a13.img.gz, there's no update to Raspberry Pi Tools add-on which is still release 11.0.0.0.

+1 on this issue.

Service (argononed.service) for Argon One case relies on this dependency. So no fan control and clean shutdown for this one until fixed.

Killom · August 14, 2023 at 12:43 AM

Quick Followup:

I've replaced the old (x86) _GPIO.so with this one from current raspianOS (64bit) image: (2023-05-03-raspios-bullseye-arm64.img)

/usr/lib/python3/dist-packages/RPi/_GPIO.cpython-39-aarch64-linux-gnu.so

(rename needed)

Seems to do the trick at least for the needs of argononed.service. Advance with caution.

Raspberry Pi Tools (Team LibreELEC - 11.0.0.0) needs to be updated none the less. Architecture changed to aarch64 with LE12

We are still waiting for an updated rpi.gpio package which finally uses the standard libgpiod method instead of the ancient, hacky direct memory access which is soon going to break.

Once that's released we'll update the package and the RPi tools addon and make it available for RPi4/aarch64 as well.

so long,

Hias

Quick heads up: I've just updated the rpi-tools addon and if builds go well it should be available from the repo in the next few days.

rpi-tools: update addon and build for aarch64 as well by HiassofT · Pull Request #8230 · LibreELEC/LibreELEC.tv

update gpiozero to 2.0 and switch from RPI.GPIO to the libgpiod-based lg-gpio, like RPiOS did in it's bookworm release Also drop the ancient adafruit libraries…

github.com

It updates gpiozero to the current 2.0 version and RPI.GPIO is now gone for good (being replaced by the libgpiod based lg-gpio), aligning with current RPiOS bookworm packages.

Any out-of-tree addons and scripts that are still using RPI.GPIO should switch to gpiozero, otherwise they won't work on LE12.

so long,

Hias

HiassofT ,

thank you for the information and providing the updated rpi-tools add-on.

ghtester ,

thank you for the direction to gpiozero documentation. I have prepared a migrated version of the ArgonForty Device Configuration add-on . But I need feedback from a brave tester with an LE12 nightly build. Killom , do you will give version 0.0.5 a try?

**chewitt** · October 25, 2023 at 4:32 AM

HarryH in addition to testing it would be easier to review changes if you push code to a GitHub repo. Feel free to reach out if you need any help with that process.

HarryH · October 26, 2023 at 7:26 PM

Hi chewitt ,

As you suggested, I opened a repo on GitHub. There are the changes for both versions (0.0.4 and 0.0.5). I actually didn't want to take this step until I could successfully build the plugin from scratch, without using the old ZIP as a basis...

**chewitt** · October 27, 2023 at 4:19 AM

btw, this is the add-on icon.png that I created for a previous Argon addon attempt, based on the normal LE house-style/template.

ghtester · November 25, 2023 at 1:05 PM

A strange issue started to happen after upgrade to latest Nightly builds with kernel 6.6.2

The python script to run in background from autostart.sh now does not work due to error generated after Button configuration:

btn = Button(5, pull_up=False)

the kernel log:

export_store: invalid GPIO 5

But when the same script is started manually from SSH console after OS boot, it works without issue.

Could somebody explain this behaviour and give an advice how to fix it please?

I tried to put a time.sleep (30) before the Button command but it did not help, so it looks like some access rights issue?

ghtester · December 16, 2023 at 1:36 PM

The issue described in post #12 still persists after upgrade to nightly-20231216-63347fc (RPi4.aarch64) with kernel 6.6.7.

**chewitt** · December 17, 2023 at 7:07 AM

Have a read here: https://www.tomshardware.com/how-to/control…o-with-python-3

The article was written for RPi5 but the changes apply to all Pi boards running the latest RPiOS release. The kernel bump to Linux 6.6 is not responsible but other changes that were packaged at/around the same time result in changes.

ghtester · December 17, 2023 at 10:41 AM

Thanks but it looks gpiod is not present in LE12.

As mentioned earlier, I have already updated the python script to use gpiozero instead of RPi.GPIO.

It worked fine until recent nightly builds. Now it still works but not from autostart.sh and I can't find the reason.

**HiassofT** · December 17, 2023 at 10:48 AM

Make sure both PYTHONPATH and LD_LIBRARY_PATH are setup correctly to include the rpi-tools addon lib dir. The latter is automatically set up if you ssh in, but not in systemd services or autostart.sh

so long,

Hias

ghtester · December 17, 2023 at 11:00 AM

Thanks as well but I believe there's no issue with the path. In fact the script works even in autostart.sh (LED can be turned on/off) except the input button.

btn = Button(5, pull_up=False)

the kernel log:

export_store: invalid GPIO 5

When the path is wrong, the script fails at import command which is not the case.

It looks I am not the only user with this issue:
