I found a DTS file that was included as part of an example of the use of the ADAFruit Python library. I compiled it and placed in /lib/firmware:
$ ls /lib/firmware 3.8.13-bone62 ADA-SPI0-01-00A0.dtbo BB-SPI0-01-00A0.dtbo I attempt to enable this overlay in uEnv.txt. uname_r=3.8.13-bone62 optargs=quiet drm.debug=7 cape_enable=bone_capemgr.enable_partno=ADA-SPI0-01 I can see that it is passed to the kernel. $ cat /proc/cmdline console=tty0 console=ttyO0,115200n8 quiet drm.debug=7 bone_capemgr. enable_partno=ADA-SPI0-01 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait However the device nodes are not created and I do not see the overlay listed. $ cat /sys/devices/bone_capemgr.*/slots 0: 54:PF--- 1: 55:PF--- 2: 56:PF--- 3: 57:PF--- 4: ff:P-O-L Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G 5: ff:P-O-L Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI 7: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-UART4 8: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-UART1 dmesg information: [ 0.552308] bone-capemgr bone_capemgr.9: Baseboard: 'A335BNLT,00C0,0816BBBK0B26' [ 0.552332] bone-capemgr bone_capemgr.9: compatible-baseboard=ti, beaglebone-black [ 0.583227] bone-capemgr bone_capemgr.9: slot #0: No cape found [ 0.620334] bone-capemgr bone_capemgr.9: slot #1: No cape found [ 0.657443] bone-capemgr bone_capemgr.9: slot #2: No cape found [ 0.694551] bone-capemgr bone_capemgr.9: slot #3: No cape found [ 0.700772] bone-capemgr bone_capemgr.9: slot #4: specific override [ 0.700795] bone-capemgr bone_capemgr.9: bone: Using override eeprom data at slot 4 [ 0.700811] bone-capemgr bone_capemgr.9: slot #4: 'Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G' [ 0.700893] bone-capemgr bone_capemgr.9: slot #5: specific override [ 0.700911] bone-capemgr bone_capemgr.9: bone: Using override eeprom data at slot 5 [ 0.700925] bone-capemgr bone_capemgr.9: slot #5: 'Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI' [ 0.700994] bone-capemgr bone_capemgr.9: slot #6: specific override [ 0.701011] bone-capemgr bone_capemgr.9: bone: Using override eeprom data at slot 6 [ 0.701025] bone-capemgr bone_capemgr.9: slot #6: 'Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN' [ 0.701356] bone-capemgr bone_capemgr.9: loader: before slot-4 BB-BONE- EMMC-2G:00A0 (prio 1) [ 0.701371] bone-capemgr bone_capemgr.9: loader: check slot-4 BB-BONE- EMMC-2G:00A0 (prio 1) [ 0.701446] bone-capemgr bone_capemgr.9: loader: before slot-5 BB-BONELT- HDMI:00A0 (prio 1) [ 0.701459] bone-capemgr bone_capemgr.9: loader: check slot-5 BB-BONELT- HDMI:00A0 (prio 1) [ 0.701494] bone-capemgr bone_capemgr.9: initialized OK.
