Dear all, May I ask for your advice regarding a device tree overlay problem occuring at boot time (Ubuntu on BBB). My MAX-GPIO-set-00A0.dtbo file works just nice when I use it manually by typing the command
echo MAX-GPIO-set > slots (in /sys/devices/bone_capemgr.*). I conclude from this that the dtbo file itself is correct. Now, when I modify uEnv.txt to load the dtbo file at boot: optargs=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN > capemgr.enable_partno=BB-UART5,MAX-GPIO-set > the MAX-GPIO-set file is not applied (however, the BB_UART5 file is applied correctly). dmesg | grep "MAX" gives the following output: [ 0.000000] Kernel command line: console=ttyO0,115200n8 > capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN > capemgr.enable_partno=BB-UART5,MAX-GPIO-set root=/dev/mmcblk0p2 ro > rootfstype=ext4 rootwait fixrtc ip= > [ 1.958351] bone-capemgr bone_capemgr.8: enabled_partno part_number > 'MAX-GPIO-set', version 'N/A', prio '0' > [ 1.983096] bone-capemgr bone_capemgr.8: slot #8: 'Override Board > Name,00A0,Override Manuf,MAX-GPIO-set' > [ 2.052857] bone-capemgr bone_capemgr.8: loader: before slot-8 > MAX-GPIO-set:00A0 (prio 0) > [ 2.061427] bone-capemgr bone_capemgr.8: loader: check slot-8 > MAX-GPIO-set:00A0 (prio 0) > [ 2.107066] bone-capemgr bone_capemgr.8: loader: after slot-8 > MAX-GPIO-set:00A0 (prio 0) > [ 2.175944] bone-capemgr bone_capemgr.8: slot #8: Requesting part > number/version based 'MAX-GPIO-set-00A0.dtbo > [ 2.197751] bone-capemgr bone_capemgr.8: slot #8: Requesting firmware > 'MAX-GPIO-set-00A0.dtbo' for board-name 'Override Board Name', version > '00A0' > [ 3.396200] bone-capemgr bone_capemgr.8: failed to load firmware > 'MAX-GPIO-set-00A0.dtbo' > [ 3.404896] bone-capemgr bone_capemgr.8: loader: failed to load slot-8 > MAX-GPIO-set:00A0 (prio 0) > Any ideas would be highly appreciated.
