Hi!
I’m wondering if you’re planning to release ELK Audio OS for the new Raspberry PI 5. It would be awesome to have more performance headroom RPI 5 brings compared to RPI 4. 
Best,
Piotr

Hi @bnkwsk,
unfortunately, this is not trivial - with the new IC that handles I2S, we will have to basically write a new driver from scratch.
I’m not excluding it completely but right now is not in our pipeline.

Any update on this?
I bought a HiFiBerry bundle, and after several days of troubleshooting I’ve discovered that I have an RPi 5, and the Elk OS image I have is only for RPi 4.

Hello @Stefano, and the rest of the ELK team !
HifiBerry released their ADC8x add-on for the DAC8x, which when combined, enables a PI 5 to get 8 mono inputs and 8 mono outputs, which would be absolutely perfect for my open source preamp project.
Any news on the support for raspberry pi 5 ?
In the meantime I will probably still get the hardware and roll my own Raspberry Pi OS + PREEMPT_RT with a Sushi build, to get some work done while waiting for ELK Audio OS, just wanted to know if you guys are still planning to support the PI 5 and maybe these new devices.
Cheers !
Hi @leozor,
unfortunately the RPi5 support is not straightforward since there have been many changes in the way that the SOC interfaces with I2S ports (it goes through the RP2040 which is connected over USB, which is quite tricky with Xenomai).
We are doing some initial investigation but so far there are no plans to start the driver work yet.
How about without drivers ?
I figured that there are still interesting features to have on a pi5 based project in elkOS even if the ultra low latency drivers are not available : barebones OS, double-partitions, system update to name a few
How easy would it be to make a preempt-rt based version of ELK OS for the pi 5 ?
If it is not a great option, if anyone knows any resources that could give me pointers on how to develop a HAT for the pi 4 with as many I/O as the DAC8X+ADC8X, and how to write drivers for elkos/pi4, that would be greatly appreciated. I am starting development for a 8 in 8 out device with the Pi 5.
I am thinking that making an audio HAT for a pi 4 would be a significantly higher challenge than making a custom midi controller PCB, but I’d still like to get a grasp of the difficulty and maybe try.
Many thanks !
