When trying to load the dtbo on the latest debian images (compiled with https://github.com/pantoniou/dtc to make it work on the 4.1 kernel) it doesn't work anymore (white blank screen) and spews: [ 192.904547] bone_capemgr bone_capemgr: part_number 'DVK530-LCD4-01', version 'N/A' [ 192.904591] bone_capemgr bone_capemgr: slot #4: override [ 192.904610] bone_capemgr bone_capemgr: Using override eeprom data at slot 4 [ 192.904628] bone_capemgr bone_capemgr: slot #4: 'Override Board Name,00A0,Override Manuf,DVK530-LCD4-01' [ 192.926396] ocp:backlight supply power not found, using dummy regulator [ 192.929198] bone_capemgr bone_capemgr: slot #4: dtbo 'DVK530-LCD4-01-00A0.dtbo' loaded; overlay id #0 [ 192.971160] ocp:backlight supply power not found, using dummy regulator [ 192.971561] pwm-backlight ocp:backlight: invalid default brightness level: 101, using 100 [ 193.014772] of_graph_get_next_endpoint(): no port node found in /ocp/fb [ 193.065022] of_graph_get_next_endpoint(): no port node found in /ocp/fb [ 193.083458] tilcdc 4830e000.fb: no encoders/connectors found
Anyone can help ? I tried to look at commits done on similar overlays (e.g. https://github.com/beagleboard/bb.org-overlays/commits/master/src/arm/BB-BONE-LCD4-01-00A1.dts which is similar) but I couldn't find anything obvious to update for 4.1.
