Does anyone have any help on this? I'm getting this too, using Ubuntu on the Beaglebone Black. I've upgrade to 3.8.13-bone31 (the only higher version is 3.12 but I can't get the cape to load)
I get some valid readings (for maybe a few minutes after I load the cape) then I get the resource temporarily unavailable, and there's nothing in the dmesg output to indicate an error :( On Monday, December 2, 2013 7:56:11 AM UTC-5, [email protected] wrote: > > I am getting resource temporary unavailable when I tried to read ADC pins > from BeagleBone Black > > root@beaglebone:~# cat /sys/devices/ocp.2/helper.11/AIN* > cat: /sys/devices/ocp.2/helper.11/AIN0: Resource temporarily unavailable > cat: /sys/devices/ocp.2/helper.11/AIN1: Resource temporarily unavailable > cat: /sys/devices/ocp.2/helper.11/AIN2: Resource temporarily unavailable > cat: /sys/devices/ocp.2/helper.11/AIN3: Resource temporarily unavailable > cat: /sys/devices/ocp.2/helper.11/AIN4: Resource temporarily unavailable > cat: /sys/devices/ocp.2/helper.11/AIN5: Resource temporarily unavailable > cat: /sys/devices/ocp.2/helper.11/AIN6: Resource temporarily unavailable > cat: /sys/devices/ocp.2/helper.11/AIN7: Resource temporarily unavailable > > What might be the reason for the error ? > The ADC pins AIN0 to AIN5 are connected to thermistors and the actual > voltage at the ADC pins is around 0.77 volt > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
