Hyperbian + Hyperion ng + ezcap 269

It's some type of clone of this: https://www.arduino.cc/en/Main/Arduino_BoardLeonardo inside that converter.
But as it's work on Rpi3 it should also work with Rpi4. I suspected some conflict with Raspbian system ports but as I tested mine seems it's not true. You can check on working Rpi3 Hyperion log what speed is set.

OK, the same ATmega32u4 with custom PCB. Probably firmware is not upgradable if the producer locked the chip. Anyway, don't touch it You can replace it with other arduino but it would require creating&connecting new setup to the LED.

First check Rpi3 & post it's log it as it's working: in debug log there should used speed. Arduino nano should be sufficient as you can find many setup build for apa102 & Hyperion on this forum.

As you can see ACM0 on Rpi4 @115200 working perfectly fine out of box:

Well, first check the value that works on Rpi3. Experiment is the last resort

Hi all, thank you for your post. this is my first contribution. i had the same issue regarding the ttyacm0 and even with your input and advise i wasn’t able to fix it. But yesterday i found the SOLUTION. In fact problem is coming from arduino apa120 firmware. So for fixing issue just follow this http://update.lightberry.eu/ . i have installed 1.1 firmware, i also kept all modification done from this forum like modification in config.txt or console instruction remove. Since yesterday no more timeout. my config is same than yours . raspbian os latest , latest firmware with rpi-update command, rpi 4, connected to usb apa120. I have also installed HyperionHDR. Hope that help you.

Hi thx for the answer.
I'm following your link but I have issues in Arduino app (I'm from Mac osx) Following the errors:

Can you help me please to understand how to do? Did you plugged the Arduino also with power or just usb?

Hi tyler !
I just unplunged usb from pi 4 and connect it to my mac. Power supply is still connected yes. When i plugged it to my mac, led strip is lightning. Then i just follow the instructions on website for upload new firmware.
Then i plugged back the arduino usb to my pi4 and start pi4.

Regards

I can select only two port. And i selected the only one with arduino mention in name.

I had this kind of behaviour before the fix. Right now all is functional. No more Timeout and no more led that remain on.
I use App android grabber hyperion on shield tv nvidia for controling led remotly from a different source than pi4. That works fine too. I made a long investigation on this issue since the change of my pi with pi4. I was almost desapointed about this but now i can enjoy it correctly !!

The firmware update (1.1 APA102) worked! Thank you so much for posting/updating this thread. I've had a "dead" Lightberry kit ever since I switched from OpenElec to HyperBian. This worked when nothing else did. Using a RPi3 FYI.

Bonus -- use these settings for the Lightberry HD kit (documented from Lightberry itself):
