Hello,
I have used a Raspberry Pi 4 with 8Byte RAM (Rev 1.4) and a Hifiberry Digi+Pro and Libreelec 9.4 for a long time. Since the Raspberry Pi with so much RAM was too good for me, I wanted to use a Raspberry Pi 4 with 2GB (Rev 1.5) with the Hifiberry Digi+ Pro, which unfortunately doesn't work. Is there a way to do a software update for the Hifiberry so that it can also handle the "new" hardware?
