Hi everyone,
obviously it is a little newbie-problem, but after hours of searching and trying I didnt get it to work.
root@beaglebone:~# uname -a
Linux beaglebone 3.8.13-bone70 #1 SMP Fri Jan 23 02:15:42 UTC 2015 armv7l GNU/Linux
I have a little project, and I would like to run a dogm-204a-display with the BBB over SPI and python. When I run the following line…
root@beaglebone:~# config-pin -f owncape2.bbio
overlaycape-universaln
Invalid mode: default
root@beaglebone:~# cat /sys/devices/bone_capemgr.*/slots
0: 54:PF—
1: 55:PF—
2: 56:PF—
3: 57:PF—

5: ff:P-O-- Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI
6: ff:P-O-- Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN
7: ff:P-O-L Override Board Name,00A0,Override Manuf,cape-universaln
everything runs without an error. Then I’m trying to run spidev in python, and get the following error:
root@beaglebone:~# python
