It is linux specific.

As for ANY other way, sure, you just do the work. Reverse engineer the chip, build your own sdk. It would take a person who as done this before who was driven and one of the best in the world - I would guess 6 months.

Is it a good idea to use linux drivers for the luckfox lyra, as a reference for when making my operating system’s drivers?

I’d definitely be open to creating a discord for this. I’ve been trying to decide whether discord is really a great choice for an open source project, but I generally agree it’s the least friction alternative right now (although i’m a bit grumpy IRC and Matrix are not..)

I was waiting on a bit of consensus on the right stack.

Here’s the discord server: Calculinux

these drivers really are not luckfox lyra specific, but rather Linux specific. the luckfox specific parts are just pin / port selection in the dtsi file.

660

So are the drivers, a good idea, to use as a reference?

661

If you plan on using Linux kernel drivers as a basis, you should familiarize yourself with Linux kernel programming first – there are a lot of important idioms in the Linux kernel that you’ll need to wrap your brain around before you get anywhere.

I don’t plan on soldering the audio to a different pin, as audio doesn’t matter to me much.

What lightweight OSs are available for the PicoCalc with the Lyra, and which have a GUI, are good for coding, good for retro gaming, etc, as until Astralixi OS is released, I would be using a different OS on my lyra, so I want some community input.

I tried to get the Ubuntu image running, but the Picocalc only shows a black screen with the image 24.04.2 ( GitHub - markbirss/ubuntu-24.04.2-picocalc: Ubuntu 24.04.2 for Clockwork PicoCalc powered by Luckfox Lyra ).

The image 24.04.5 ( GitHub - markbirss/ubuntu_22.04.5_lts_picocalc: Ubuntu 22.04.5 LTS for PicoCalc with Luckfox Lyra Core ) is only a bit over 400 MB in total and doesn’t seem to be the correct one. Does anyone have a working Ubuntu image ready to use?

I tryed both,Please confirm both of your image is transfered correctly (for 24.04 the update.img size should be 9.79 GB and 22.04 is 933 MB ,you need to check the md5 of every file to Precisely confirm everything is correct）。
and for beginers，use the RKDEVtool to flash this image is more reliable shince the DD way is more manual only suit for advanced user knowing how all things is working.
