I am having a similar problem as described above. I am trying to load a custom cape.
I am trying to load a copy of BB-BONE-LCD4.dts. Eventually I plan to modify this overlay to include an LCD panel, but for now i've *cloned the dts file*, changed the part number to DOPTOCAPE1, and renamed the file DOPTOCAPE1.dts I placed the file in /src/arm directory, then ran install.sh I cheked that DOPTOCAPE1.dtbo is now in /lib/firmware Then I made the changes in my uEnv.txt file, and rebooted. Here is debug from the boot process: [ 0.000000] Kernel command line: console=ttyO0,115200n8 capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN capemgr.enable_partno=dev_OPTOCAPE root=UUID=509a5094-05c2-4cf0-803d-945708cd72b5 ro rootfstype=ext4 rootwait coherent_pool=1M quiet net.ifnames=0 [ 0.610669] bone-capemgr bone_capemgr.9: Baseboard: 'A335BNLT,000C,3914BBBK2717' [ 0.610691] bone-capemgr bone_capemgr.9: compatible-baseboard=ti,beaglebone-black [ 0.610729] bone-capemgr bone_capemgr.9: Skipping disabled cape with part# BB-BONELT-HDMI [ 0.610773] bone-capemgr bone_capemgr.9: Skipping disabled cape with part# BB-BONELT-HDMIN [ 0.641898] bone-capemgr bone_capemgr.9: slot #0: No cape found [ 0.679000] bone-capemgr bone_capemgr.9: slot #1: No cape found [ 0.716114] bone-capemgr bone_capemgr.9: slot #2: No cape found [ 0.753223] bone-capemgr bone_capemgr.9: slot #3: No cape found [ 0.759455] bone-capemgr bone_capemgr.9: slot #4: specific override [ 0.759476] bone-capemgr bone_capemgr.9: bone: Using override eeprom data at slot 4 [ 0.759492] bone-capemgr bone_capemgr.9: slot #4: 'Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G' [ 0.759565] bone-capemgr bone_capemgr.9: slot #5: specific override [ 0.759582] bone-capemgr bone_capemgr.9: bone: Using override eeprom data at slot 5 [ 0.759595] bone-capemgr bone_capemgr.9: slot #5: 'Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI' [ 0.759667] bone-capemgr bone_capemgr.9: slot #6: specific override [ 0.759683] bone-capemgr bone_capemgr.9: bone: Using override eeprom data at slot 6 [ 0.759696] bone-capemgr bone_capemgr.9: slot #6: 'Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN' [ 0.759755] bone-capemgr bone_capemgr.9: enabled_partno part_number 'dev_OPTOCAPE', version 'N/A', prio '0' [ 0.759768] bone-capemgr bone_capemgr.9: slot #7: generic override [ 0.759779] bone-capemgr bone_capemgr.9: bone: Using override eeprom data at slot 7 [ 0.759792] bone-capemgr bone_capemgr.9: slot #7: 'Override Board Name,00A0,Override Manuf,dev_OPTOCAPE' [ 0.759896] bone-capemgr bone_capemgr.9: Skipping loading of disabled cape with part# BB-BONELT-HDMI [ 0.759908] bone-capemgr bone_capemgr.9: Skipping loading of disabled cape with part# BB-BONELT-HDMIN [ 0.760092] bone-capemgr bone_capemgr.9: loader: before slot-4 BB-BONE-EMMC-2G:00A0 (prio 1) [ 0.760107] bone-capemgr bone_capemgr.9: loader: check slot-4 BB-BONE-EMMC-2G:00A0 (prio 1) [ 0.760134] bone-capemgr bone_capemgr.9: initialized OK.

I rebooted, and this overlay loaded with no problems. Then I tried loading manually with: echo BB-BONE-LCD4-01 >/sys/devices/bone_capemgr.9/slots This worked also. When I tried the same with my custom file, the shell returned: sh: I/O error So it seems I am having a problem loading custom .dtbo files. My kernel info is: Linux beaglebone 3.8.13-xenomai-r81 #1 Fri Oct 14 16:24:43 UTC 2016 armv7l GNU/Linux Do I need to upate my kernel?
