Hi, I etched an SD with HIFIBerry OS and booted it on a RPi 3B+ connected with an AMP100. First the Boot-Screen appeares like its descripted in the installing manual. Then, after a few minutes the system reboots and the boot-screen appears again. This repeats all the time, so it seems to be captured in a boot loop. When I disconnect the AMP100 the system starts normally, but with the AMP100 connected it doesn't work. Do you have any idea what the problem is? Thanks.
