I just updated my Beaglebone Black to: Linux beaglebone 3.8.13-bone70 #1 SMP Fri Jan 23 02:15:42 UTC 2015 armv7l GNU/Linux
I'm trying to get the eQEP working. I would like to use the alternate pinout for eQEP2 that doesn't conflict with the HDMI. I think it should use PyBBIO-eqep2b-00A0.dtbo When I use the command: echo bone_eqep2b > /sys/devices/bone_capemgr.9/slots I get: -bash: /sys/devices/bone_capemgr.9/slot: No such file or directory dmesg shows: [ 156.166488] bone-capemgr bone_capemgr.9: part_number 'bone_eqep2b', version 'N/A' [ 156.166667] bone-capemgr bone_capemgr.9: slot #7: generic override [ 156.166712] bone-capemgr bone_capemgr.9: bone: Using override eeprom data at slot 7 [ 156.166760] bone-capemgr bone_capemgr.9: slot #7: 'Override Board Name,00A0,Override Manuf,bone_eqep2b' [ 156.167027] bone-capemgr bone_capemgr.9: slot #7: Requesting part number/version based 'bone_eqep2b-00A0.dtbo [ 156.167075] bone-capemgr bone_capemgr.9: slot #7: Requesting firmware 'bone_eqep2b-00A0.dtbo' for board-name 'Override Board Name', version '00A0' [ 156.240762] bone-capemgr bone_capemgr.9: failed to load firmware 'bone_eqep2b-00A0.dtbo' If I try: echo bone_eqep2 > /sys/devices/bone_capemgr.9/slots I don't get the "No such file or directory" error dmesg shows: [ 312.600610] bone-capemgr bone_capemgr.9: part_number 'bone_eqep2', version 'N/A' [ 312.600799] bone-capemgr bone_capemgr.9: slot #8: generic override [ 312.600845] bone-capemgr bone_capemgr.9: bone: Using override eeprom data at slot 8 [ 312.601071] bone-capemgr bone_capemgr.9: slot #8: 'Override Board Name,00A0,Override Manuf,bone_eqep2' [ 312.605781] bone-capemgr bone_capemgr.9: slot #8: Requesting part number/version based 'bone_eqep2-00A0.dtbo [ 312.605841] bone-capemgr bone_capemgr.9: slot #8: Requesting firmware 'bone_eqep2-00A0.dtbo' for board-name 'Override Board Name', version '00A0' [ 312.605907] bone-capemgr bone_capemgr.9: slot #8: dtbo 'bone_eqep2-00A0.dtbo' loaded; converting to live tree [ 312.606448] bone-capemgr bone_capemgr.9: slot #8: #3 overlays [ 312.620816] pinctrl-single 44e10800.pinmux: pin 44e108b8 already requested by hdmi.13; cannot claim for 48304180.eqep [ 312.632288] pinctrl-single 44e10800.pinmux: pin-46 (48304180.eqep) status -22 [ 312.639920] pinctrl-single 44e10800.pinmux: could not request pin 46 on device pinctrl-single [ 312.675364] eqep 48304180.eqep: unable to select pin group [ 312.677533] bone-capemgr bone_capemgr.9: slot #8: Applied #3 overlays.
