error on tool/download-tool

Hi,

I tried to build a libreElec from git - but download-tool fails with

I guess, the old one (kmscube-98f31bf.tar.xz) does not work?

When building master the sources have to be downloaded from the original source, error 404 from sources.libreelec.tv is a Red Herring.

Check why download try from Mesa / kmscube · GitLab failed before.

Thank you for that sophisticated response

Didn't heard about Red Herring before - so I learned at trying to understand your response. Fine!

So I did the download again - this time with logging.

Of cause - you where right.

First error is this:

When I start the download-tool again (without cleaning the download-cache), the checksum error does not appear. Only the second part (404) will happen.

you don't need to run the download tool

all necessary stuff gets downloaded while you build it, so you don't download kmscube if you build generic for example

tony013 · April 18, 2021 at 3:53 PM

Hi,

I don't want to build a Generic one.

The reason for me to build a libreElec from git is, that Penta Sata needs a controller for the included fan to work.

On debian its possible to install the driver from radxa, but for other linux variants there's no support.

So I looked into the driver that controls the fan and it consists of just a few python scripts. Not difficult to port/migrate, but libreElec does not have a pip with python. So no way to extend libreElec.

All other linux variants, that have a mature python support and run on the rock pi4 don't have hardware support for video and don't have multichannel audio over hdmi neither ...

So extending libreElec is the only choice for me.

But I don't have experience in patching linux or experience with python or libreElec, so I can't do the job without your help.

after a quick look I think there should be everything there already

they ship some python scripts and install a kitchen sink of depends from pip

Quote from tony013

install the driver from radxa

they install

https://s3.setq.io/rockpi/deb/rockpi-penta-0.10.deb the fan.py

https://s3.setq.io/rockpi/pypi/Adafruit_SSD1306-v1.6.2.zip the driver ?

and make some changes at the pin output

The "driver" is already there LibreELEC.tv/packages/addons/addon-depends/adafruit-libraries-depends/Adafruit_Python_SSD1306 at master · LibreELEC/LibreELEC.tv · GitHub so likely it should just some copy/paste needed to have it working. Not sure if anything else is missing.

just the oled.py looks fishy, but nothing that can't be done I think

tony013 · April 18, 2021 at 6:21 PM

Thank you very much for your attention!

Don't know, whether I got it right. I did just some quick research.

If I got it right, then adafruit is a driver for the little display on top.

"rockpi-penta" is the fan driver.

At debian it installs the following python packages:

Code

python3-rpi.gpio
python3-setuptools
python3-pip
python3-pil
python3-spidev
pigpio
python3-pigpio

I issued a 'python help modules' to see, which of the modules is already installed and it looked as none of the above packages is available at libreElec.

But ...

... I have no idea of python and its internals, so I can be wrong.

I guess the "rpi.gpio" is needed for the pwm to control fanspeed. "spidev" might be used to connect the display ...

I only want the fan control and nice to have (if possible) the control of the top button - which might be useful to restart the box after shutdown (without switching power off and on). I have no plans in using the display ...

Checksum of package downloaded from GitLab has changed. Update packages/graphics/kmscube/package.mk.

PS: With my Generic setup I cannot download/test kmscube. If there is a volunteer for a fix ...

tony013 · April 19, 2021 at 2:27 PM

Thank you for the location of the checksum origin.

I already suspect such, but didn't know, how to fix it.

Now download succeeded completely.
