Hello,
About a month ago, I installed aarch64 on a Raspberri Pi 4B using the instructions here at the alarm site. I then updated using the instructions at @graysky 's repo-ck site. All worked well.
Over the weekend, I installed aarch64 on another rpi 4b. I'm having a couple of issues.
1. My previous installation added several lines to the /boot/config.txt file. In the new installation, the only line added to this file is "enable_uart=1". I found that this has been sufficient to get a nearly functional system (I haven't gotten audio to work yet; see #5 below). I suspect this is because I need to add some line to the /boot/config.txt file. More on that...
2. The /boot/overlays folder is missing from this new install. Is that by design? Did the overlay files move, or are they not needed any longer? The README file in this folder was a nice reference, I think.
3. The /boot/cmdline.txt file also was not created. Is it no longer needed?
4. The (now missing) /boot/cmdline.txt file is where I added "audit=0" to stop the audit messages from flooding my terminal. Is there another way to to do this now?
5. Following my install last month, everything worked. It was great. With this new install, I cannot get audio to work. Is it likely due to one of the "missing" files above? I know I haven't provided much in the way of detail to troubleshooting my audio issue, but I'm hoping that the answers to the above will solve this issue. I'm happy to provide more details if needed.
Thank you for your help!
