okay, had a chance to test this and enable them.. cd /opt/source/bb.org-overlays/ git pull ./install.sh sudo reboot root@beaglebone:~# config-pin overlay cape-universal Loading cape-universal overlay [ 36.591695] bone_capemgr bone_capemgr: part_number 'cape-universal', version 'N/A' [ 36.612105] bone_capemgr bone_capemgr: slot #4: override [ 36.629826] bone_capemgr bone_capemgr: Using override eeprom data at slot 4 [ 36.636895] bone_capemgr bone_capemgr: slot #4: 'Override Board Name,00A0,Override Manuf,cape-universal' [ 37.071214] gpio-of-helper ocp:cape-universal: Allocated GPIO id=0 [ 37.098140] gpio-of-helper ocp:cape-universal: Allocated GPIO id=1 [ 37.104719] gpio-of-helper ocp:cape-universal: Allocated GPIO id=2 [ 37.148301] gpio-of-helper ocp:cape-universal: Allocated GPIO id=3 [ 37.154883] gpio-of-helper ocp:cape-universal: Allocated GPIO id=4 [ 37.194330] gpio-of-helper ocp:cape-universal: Allocated GPIO id=5 [ 37.206406] gpio-of-helper ocp:cape-universal: Allocated GPIO id=6 [ 37.236009] gpio-of-helper ocp:cape-universal: Allocated GPIO id=7 [ 37.258126] gpio-of-helper ocp:cape-universal: Allocated GPIO id=8 [ 37.264734] gpio-of-helper ocp:cape-universal: Allocated GPIO id=9 [ 37.308109] gpio-of-helper ocp:cape-universal: Allocated GPIO id=10 [ 37.314793] gpio-of-helper ocp:cape-universal: Allocated GPIO id=11 [ 37.348126] gpio-of-helper ocp:cape-universal: Allocated GPIO id=12 [ 37.354781] gpio-of-helper ocp:cape-universal: Allocated GPIO id=13 [ 37.390272] gpio-of-helper ocp:cape-universal: Allocated GPIO id=14 [ 37.396931] gpio-of-helper ocp:cape-universal: Allocated GPIO id=15 [ 37.438234] gpio-of-helper ocp:cape-universal: Allocated GPIO id=16 [ 37.444926] gpio-of-helper ocp:cape-universal: Allocated GPIO id=17 [ 37.488201] gpio-of-helper ocp:cape-universal: Allocated GPIO id=18 [ 37.494891] gpio-of-helper ocp:cape-universal: Allocated GPIO id=19 [ 37.528007] gpio-of-helper ocp:cape-universal: Allocated GPIO id=20 [ 37.534716] gpio-of-helper ocp:cape-universal: Allocated GPIO id=21 [ 37.568106] gpio-of-helper ocp:cape-universal: Allocated GPIO id=22 [ 37.574765] gpio-of-helper ocp:cape-universal: Allocated GPIO id=23 [ 37.617756] gpio-of-helper ocp:cape-universal: Allocated GPIO id=24 [ 37.641455] gpio-of-helper ocp:cape-universal: Allocated GPIO id=25 [ 37.651377] gpio-of-helper ocp:cape-universal: Allocated GPIO id=26 [ 37.677719] gpio-of-helper ocp:cape-universal: Allocated GPIO id=27 [ 37.697700] gpio-of-helper ocp:cape-universal: Allocated GPIO id=28 [ 37.717755] gpio-of-helper ocp:cape-universal: Allocated GPIO id=29 [ 37.730354] gpio-of-helper ocp:cape-universal: Allocated GPIO id=30 [ 37.750794] gpio-of-helper ocp:cape-universal: Allocated GPIO id=31 [ 37.771213] gpio-of-helper ocp:cape-universal: Allocated GPIO id=32 [ 37.793389] gpio-of-helper ocp:cape-universal: Allocated GPIO id=33 [ 37.813290] gpio-of-helper ocp:cape-universal: Allocated GPIO id=34 [ 37.830964] gpio-of-helper ocp:cape-universal: Allocated GPIO id=35 [ 37.850323] gpio-of-helper ocp:cape-universal: ready [ 37.869635] 48022000.serial: ttyS1 at MMIO 0x48022000 (irq = 179, base_baud = 3000000) is a 8250 [ 37.913765] 48024000.serial: ttyS2 at MMIO 0x48024000 (irq = 180, base_baud = 3000000) is a 8250 [ 37.965252] 481a8000.serial: ttyS4 at MMIO 0x481a8000 (irq = 181, base_baud = 3000000) is a 8250 [ 38.056564] omap_i2c 4802a000.i2c: bus 1 rev0.11 at 100 kHz [ 38.083959] bone_capemgr bone_capemgr: slot #4: dtbo 'cape-universal-00A0.dtbo' loaded; overlay id #0 [ 38.320777] CAN device driver interface [ 38.385921] pruss_uio 4a300000.pruss: pins are not configured from the driver [ 38.507182] c_can_platform 481cc000.can: c_can_platform device registered (regs=fa1cc000, irq=190) [ 38.628029] c_can_platform 481d0000.can: c_can_platform device registered (regs=fa1d0000, irq=191) root@beaglebone:~# ls /sys/class/pwm/ pwmchip0 pwmchip2 pwmchip4 pwmchip6 pwmchip7 Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
