Beaglebone Black and LCD7 Cape not Working

Asked by 4 months ago
I just loaded my Beaglebone Black with Archlinux and things are working well...except that the LCD drivers don't seem to load at startup. From looking at the board it appears that others have had success where I am only getting a blank screen. Here is the relevant part of the DMESG traffic: [ 1.770403] bone-capemgr bone_capemgr.6: Baseboard: 'A335BNLT,0A5C,2813BBBK2343' [ 1.778273] bone-capemgr bone_capemgr.6: compatible-baseboard=ti, beaglebone-black [ 1.810321] bone-capemgr bone_capemgr.6: slot #0: 'BeagleBone LCD7 CAPE,00A3,Beagleboardtoys,BB-BONE-LCD7-01' [ 1.860879] bone-capemgr bone_capemgr.6: slot #1: No cape found [ 1.904876] bone-capemgr bone_capemgr.6: slot #2: No cape found [ 1.948874] bone-capemgr bone_capemgr.6: slot #3: No cape found [ 1.955165] bone-capemgr bone_capemgr.6: slot #4: specific override [ 1.961831] bone-capemgr bone_capemgr.6: bone: Using override eeprom data at slot 4 [ 1.969944] bone-capemgr bone_capemgr.6: slot #4: 'Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G' [ 1.980211] bone-capemgr bone_capemgr.6: slot #5: specific override [ 1.986877] bone-capemgr bone_capemgr.6: bone: Using override eeprom data at slot 5 [ 1.994988] bone-capemgr bone_capemgr.6: slot #5: 'Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI' [ 2.005113] bone-capemgr bone_capemgr.6: slot #6: specific override [ 2.011774] bone-capemgr bone_capemgr.6: bone: Using override eeprom data at slot 6 [ 2.019886] bone-capemgr bone_capemgr.6: slot #6: 'Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN' [ 2.030567] bone-capemgr bone_capemgr.6: loader: before slot-0 BB-BONE- LCD7-01:00A3 (prio 0) [ 2.039528] bone-capemgr bone_capemgr.6: loader: check slot-0 BB-BONE- LCD7-01:00A3 (prio 0) [ 2.048492] bone-capemgr bone_capemgr.6: loader: before slot-4 BB-BONE- EMMC-2G:00A0 (prio 1) [ 2.057435] bone-capemgr bone_capemgr.6: loader: check slot-4 BB-BONE- EMMC-2G:00A0 (prio 1) [ 2.066391] bone-capemgr bone_capemgr.6: loader: before slot-5 BB-BONELT- HDMI:00A0 (prio 1) [ 2.075240] bone-capemgr bone_capemgr.6: loader: check slot-5 BB-BONELT- HDMI:00A0 (prio 1) [ 2.084030] bone-capemgr bone_capemgr.6: initialized OK.

I don't really want to have to dig deeply into device trees so am hoping someone can short cut me! I did try moving the LCD7 files from a working Angtrom OS onto the Arch instance but that gave me the following: [ 1.770403] bone-capemgr bone_capemgr.6: Baseboard: 'A335BNLT,0A5C,2813BBBK2343' [ 1.778273] bone-capemgr bone_capemgr.6: compatible-baseboard=ti, beaglebone-black [ 1.810321] bone-capemgr bone_capemgr.6: slot #0: 'BeagleBone LCD7 CAPE,00A3,Beagleboardtoys,BB-BONE-LCD7-01' [ 1.860879] bone-capemgr bone_capemgr.6: slot #1: No cape found [ 1.904876] bone-capemgr bone_capemgr.6: slot #2: No cape found [ 1.948874] bone-capemgr bone_capemgr.6: slot #3: No cape found [ 1.955165] bone-capemgr bone_capemgr.6: slot #4: specific override [ 1.961831] bone-capemgr bone_capemgr.6: bone: Using override eeprom data at slot 4 [ 1.969944] bone-capemgr bone_capemgr.6: slot #4: 'Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G' [ 1.980211] bone-capemgr bone_capemgr.6: slot #5: specific override [ 1.986877] bone-capemgr bone_capemgr.6: bone: Using override eeprom data at slot 5 [ 1.994988] bone-capemgr bone_capemgr.6: slot #5: 'Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI' [ 2.005113] bone-capemgr bone_capemgr.6: slot #6: specific override [ 2.011774] bone-capemgr bone_capemgr.6: bone: Using override eeprom data at slot 6 [ 2.019886] bone-capemgr bone_capemgr.6: slot #6: 'Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN' [ 2.030567] bone-capemgr bone_capemgr.6: loader: before slot-0 BB-BONE- LCD7-01:00A3 (prio 0) [ 2.039528] bone-capemgr bone_capemgr.6: loader: check slot-0 BB-BONE- LCD7-01:00A3 (prio 0) [ 2.048492] bone-capemgr bone_capemgr.6: loader: before slot-4 BB-BONE- EMMC-2G:00A0 (prio 1) [ 2.057435] bone-capemgr bone_capemgr.6: loader: check slot-4 BB-BONE- EMMC-2G:00A0 (prio 1) [ 2.066391] bone-capemgr bone_capemgr.6: loader: before slot-5 BB-BONELT- HDMI:00A0 (prio 1) [ 2.075240] bone-capemgr bone_capemgr.6: loader: check slot-5 BB-BONELT- HDMI:00A0 (prio 1) [ 2.084030] bone-capemgr bone_capemgr.6: initialized OK.
