my problem is that I cant install bonescript and a lot of ports do not exist like this port. /sys/devices/ocp.2/helper.14/AIN5
I think i will go back to *angstrom*. or shuld be better debian? root@ubuntu-armhf:/sys/kernel/debug/pinctrl/44e10800.pinmux# export SLOTS=/sys/devices/bone_capemgr.9/slots root@ubuntu-armhf:/sys/kernel/debug/pinctrl/44e10800.pinmux# export PINS=/sys/kernel/debug/pinctrl/44e10800.pinmux/pins root@ubuntu-armhf:/sys/kernel/debug/pinctrl/44e10800.pinmux# echo $SLOTS /sys/devices/bone_capemgr.9/slots root@ubuntu-armhf:/sys/kernel/debug/pinctrl/44e10800.pinmux# echo $PINS /sys/kernel/debug/pinctrl/44e10800.pinmux/pins root@ubuntu-armhf:/home/ubuntu# cat $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 root@ubuntu-armhf:/home/ubuntu/boneDeviceTree/overlay# dtc -O dtb -o DM-GPIO-Test-00A0.dtbo -b 0 -@ DM-GPIO-Test.dts it get error and do not copile the line above root@ubuntu-armhf:/home/ubuntu/boneDeviceTree/overlay# apt-get install bonescript Reading package lists...
