Re: Moving Linux Kernel to 5.4

<QUESTION SOLVED> I am now happily using the latest 5.4 kernel on my Pi3/4 systems, and the new VC4 HDMI ARM-side audio device, and it works great: it allows me to use smaller buffers than the previous...ahem... solution, etc. All in all, awesome work on that :) However, it doesn't seem to support ...

rpi-update depending on legacy BCRM libs?

Hi, I run the new graphics stack on the Pi3 and Pi4 (KMS/DRM, new HDMI audio device, etc), so I had to remove the legacy BRCM stuff from my system because it conflicts with the new lib (mesa for GLES2 instead of the closed BRCM blobs, etc). Now rpi-update is telling me that I am missing libvchicq, v...

Re: Package containig legacy BCM libs?

<cough> https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=275372 </cough> Enjoy. OP's post is a bit strangely worded but I think they're talking about the lack of a Lite version. I am simply asking about the name of the package containing the BCM libs and headers, so I can purge it via APT-GET.

Hi there, Since there is no 64bit Rasberry Pi OS, I am building a custom system from the 64bit BETA Raspberry Pi OS.

So, is the new KMS HDMI audio device supposed to work in 64bit mode? Or maybe not yet? Thanks! Should do. Make sure you don't have any additional alsa config files.

Re: Moving Linux Kernel to 5.4

@dom: I have come back to Rasperry OS (64bit) after a LONG time using my own custom Debian AARCH64 systems. So, I was surprised that the audio was at last taken to the ARM side too!

Thanks for your responses, guys.
Yes, we need them for a project where power supply is not going to be the official one.
So, isnt board version printed in the board itself? That was the case for previous Pis.
