Hi: I'm running BeagleBoard.org Debian Image 2016-08-28 which is running the 4.4.19-ti-r41 kernel. I've disabled the HDMI (audio and video) and want to use the eQEPs.
*ls /lib/firmware/ | grep -i eqep* bone_eqep0-00A0.dtbo bone_eqep1-00A0.dtbo bone_eqep2-00A0.dtbo bone_eqep2b-00A0.dtbo PyBBIO-eqep0-00A0.dtbo PyBBIO-eqep1-00A0.dtbo PyBBIO-eqep2-00A0.dtbo PyBBIO-eqep2b-00A0.dtbo shows I have several options. However none seem to work. *echo bone_eqep1 > $SLOTS* -bash: echo: write error: File exists *dmesg* [Sep14 16:15] bone_capemgr bone_capemgr: part_number 'bone_eqep1', version 'N/A' [ +0.000075] bone_capemgr bone_capemgr: slot #9: override [ +0.000045] bone_capemgr bone_capemgr: Using override eeprom data at slot 9 [ +0.000046] bone_capemgr bone_capemgr: slot #9: 'Override Board Name,00A0,Override Manuf,bone_eqep1' [ +0.012094] bone_capemgr bone_capemgr: slot #9: bone_eqep1 conflict P8.35 (#4:univ-emmc) [ +0.008573] bone_capemgr bone_capemgr: slot #9: Failed verification So it looking like the emmc overlay is controlling the pin. What's the correct way to get emmc overlay to let me use the pin? Do I have to get dtb-4.4-ti and edit am335x-boneblack-emmc-overlay.dtb? If so, what do I edit? I'm looking for a general approach that I can apply to other pins I want to control.
