Hi!

Can I use Hifiberry OS with AMP2? I've downloaded Raspberry4 image and installed it with Etcher. However my Raspberry doesn't boot and cannot login?

Is there something special here or is this working with AMP2?

  There is a green led which is flashing 7 times = kernel.img not found?

  It's not a scdard problem because I tested same card and rAudio image and it worked ok.

  7 blinks show that the kernel has not been found. Either you didn't write it correctly or you use the wrong image for your Pi.

  ok... I have Raspberry Pi 4... which is right image?

  I downloaded this: hifiberryos-pi4.zip (https://www.hifiberry.com/images/hifiberryos-pi4.zip)

  kernl.img is on the DOS partition. If it's not there, there is some problem with your SD card writing program.

  Hmm... In the image file: hifiberryos-20230404-pi4.img I cannot find kernel.img file:

  Also I am using newest BalenaEtcher 1.18.8 and all others (tested 3 different images) this writing works well. And it feel ineteresting if all others wrote well but this one doesn't?

  Ok... there is zImage file in the FAT partition:
  
  

  And config.txt:

  That's exactly right. I cna't say why your Pi doesn't boot. My only guess is that this Pi is not a Pi4

  Unfortunately I have no idea why your Pi doesn't boot this. You can try an older release from here:
  https://github.com/hifiberry/hifiberry-os/releases
  
  We haven't heard from other users about a bahaviour like this.

  Tried couple... same problem. This is sad... I'd like to test this one - currently using Volumio.

  Very strange. One thing you can still try: Boot Raspberry Pi OS and update the boot loader. Maybe this is an early version that doesn't support reading config.txt (which would be strange, but I have no other idea why your Pi4 doesn't find the kernel).
