I just a fresher did the servo test with my BBB, however, when I use some command as (http://www.phys-x.org/rbots/index.php?option=com_content&view=article&id=106:lesson-3-beaglebone-black-pwm&catid=46:beaglebone-black&Itemid=81) tutorial, I just find some serious problem with my pwm setting.
ubuntu@ubuntu-ianymu:/sys/devices/ocp.2/pwm_test_P8_13.14$ ls
modalias power subsystem uevent
I consider there are missing some file with my BBB. it should includes , , ,
.
So I try to use update it does not work, and use
sudo sh -c "echo am33xx_pwm > /sys/devices/bone_capemgr.9/slots"
sudo sh -c "echo bone_pwm_P8_13 > /sys/devices/bone_capemgr.9/slots"
it all did not worked on it.
Guys, I have already asked many ask forum about this question, no one know how to fix that. somebody suggest me to change the DEBIAN or ANGSTROM.
I would like to figure it out what's going on with that problem.
Anyone can help me to solve that?
So, there are some information about my bbb and environment.
