Re: [beagleboard] File writing from PRU

Thanks Charles. I agree that it seems to be impossible to write to the ARM file system. I wanted to do it to get better diagnostic information while I am debugging my PRU firmware. I'm finding that turning on outputs when I reach certain sections of firmware is growing tiresome. I might try

[beagleboard] File writing from PRU

I need some help from someone who has succeeded in getting the PRU to write files onto the host's file system. I have tried two methods: 1. Using open, fputs, fprintf, etc. This does not work for me. First of all, unless I set the printf_support flag to minimal, even a simple program with only

You can create an image of your BBB image, with all your changes to is. That image will be stored on a computer. You can then copy that image to your 100 new BBBs. The exact method of doing this varies based on the computer operating system you are using. Google for "how do I save an image

Thanks for that information, Robert. That might be just what I need. I am currently using a March version so I am a little old. Any reason I shouldn't try the Stretch version? Now in the event I find I do need the USB based adapter in addition to the built-in adapter, do the later versions

[beagleboard] BB Blue reliability

A few weeks ago there were a few posts from people that had fried their BB Blue power supply circuitry. That caused me to be wary of purchasing a BB Blue for my project. Since then I've heard nothing further about this problem. Maybe those instances were outliers. Anyone else having

[beagleboard] BB Blue with single pulse encoder input

Mark I suspect your cheap encoder is incompatible with the Blue. The BB Blue is designed to operate with quadrature encoders. The Sparkfun site does not indicate your encoders are quadrature. There's a lot of other gobblygook in their encoder specifications...magnets and sensors etc...but
