Having the hardest time with my beaglebone blue. first and foremost, i followed the instructions after firing the unit up the first time, and flashed the latest image. Since then, all i can attribute that to is lack of knowledge on my part.I purchased this board because it had the built in functionality of pwms, motor drivers, servo drivers and 2s Lipo charging etc.
At this point i am looking for a stable, functional image that will work with Python, and if possible node red. I have no history or knowledge of javascript or C++, so i am trying to work my way up starting here, and teach my kids the fun tht can be had. As I am finding though, there isn't an overlay set up for the Blue, most of the pins aren't exported, and as such, rcpy doesn't want to work correctly. Even running the basic included functions yields issues like this: can't open: /sys/devices/platform/ocp/ocp:H18_pinmux/state Pinmux: No such file or directory can't open: /sys/devices/platform/ocp/ocp:C18_pinmux/state Pinmux: No such file or directory can't open: /sys/devices/platform/ocp/ocp:P9_22_pinmux/state Pinmux: No such file or directory can't open: /sys/devices/platform/ocp/ocp:P9_21_pinmux/state Pinmux: No such file or directory can't open: /sys/devices/platform/ocp/ocp:P9_26_pinmux/state Pinmux: No such file or directory can't open: /sys/devices/platform/ocp/ocp:P9_24_pinmux/state Pinmux: No such file or directory can't open: /sys/devices/platform/ocp/ocp:P9_30_pinmux/state Pinmux: No such file or directory can't open: /sys/devices/platform/ocp/ocp:P9_29_pinmux/state Pinmux: No such file or directory can't open: /sys/devices/platform/ocp/ocp:P9_31_pinmux/state Pinmux: No such file or directory WARNING: missing PINMUX driver You probbaly just need a newer kernel ERROR: export failed for hrpwm1 channel A ERROR: failed to initialize hrpwm1 WARNING: Failed to initialize motors ERROR: pru-rproc driver missing this of course persists across all of the included examples. and as such, i can't even get the motors to operate. Blinking the LED's is only useful to a point. i'm running the 4.9 kernel that came with the 2018-03-05 image. If there's a functioning image i should be using that's up to date enough i'd be happy to reflash. at this point, i'm looking for something that just works and allows all of the functions and pins the board has to work correctly. I've been advised i can manually set pins with sudo and and use other libraries. If i'm expecting too much, and there are some good resources i should look at to make this work correctly i'd be happy to delve deeper. im not afraid to learn, but i am afraid i wasted $80 on a board that did work 12 months ago, and got left behind as the rest of the world updated. Any pointers, educational resources, or even projects would be appreciated, as my children may find these interesting as well. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
