Hi Ramax,
your information really helped me in trying to install vyos on my apu 3b4 board, thank you!
At the moment I can start the modified iso but the system allways freezes during HW detection, regardless of default or debug boot.
I tried a whole bunch of usb sticks now and my last hope is to try booting from sd card.
So what does “Dump the new image to a SD card” mean? cp the iso file to a freshly formatted SD?
