It seems that P8_3 is used by the eMMC by default. I am using Debian 8.6 (2016-11-27). When I first tried config-pin for that pin, I got this error: debian@beaglebone:~$ config-pin -q P8.3 P8_03 pinmux file not found! cape-universala overlay not found run "config-pin overlay cape-universala" to load the cape I edited /boot/uEnv.txt to use dtb that disables eMMC and enabled cape-universala: uname_r=4.4.39-ti-r79 dtb=am335x-boneblack-overlay.dtb cmdline=coherent_pool=1M quiet cape_universal=enable cape_enable=bone_capemgr.enable_partno=cape-universala After rebooting, the cape-universala overlay is loaded: debian@beaglebone:~$ cat /sys/devices/platform/bone_capemgr/slots 0: PF---- -1 1: PF---- -1 2: PF---- -1 3: PF---- -1 4: P-O-L- 0 Override Board Name,00A0,Override Manuf,cape-universala P8_3 can now be set in GPIO mode with config-pin: debian@beaglebone:~$ sudo config-pin -q P8.3 P8_03 Mode: default Direction: in Value: 1 debian@beaglebone:~$ sudo config-pin -l P8.3 default gpio gpio_pu gpio_pd debian@beaglebone:~$ sudo config-pin P8.3 gpio debian@beaglebone:~$ sudo config-pin -q P8.3 P8_03 Mode: gpio Direction: in Value: 1 -drew -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
