I’m running an RPI-2, HifiBerry DAC+, and RPI 7-inch touchscreen.
Everything works fine until I install/set the SD Card Protection to Read-Only. After a reboot, the touch screen ignores touches and the hifiberry no longer plays. On occasion, the 7-in display will get random lines and colors in it. About 1 in every 4 reboots will be successful.
Just wondering if there are any compatibility issues with the SD Protection add-on and my hardware listed above. I don’t believe this is a power supply issue as I’m running a 5.1V @5A supply fed by soldered #18 gauge wire directly to the board(s).
