There is another way to go about this bit is slightly more complex, and would require an additional "server" somewhere. This server could be another embedded Linux system if you so wished. Such as a beaglebone. But basically how this works if you have an MQTT broker running locally, with the MQTT

I am a programmer, and have hands on with doing a few projects that fall into this category. What you're attempting to do does not sound very hard at all. But it could turn out to be fairly complex in nature. Tacking a few ADC values, GPI value as well as "toggling" a few GPO's is not that hard. Wh

Hi all, first off, I'm not a programmer so the reason for this question. I want to see if there is already a BBB application to allow it to be used for telemetry and or could be modified for what I need. I am able to supply an interface board that can go from the headers of the BBB to do all th

Sorry, I get into thinking about some things, and forget the minor details of other things. So, dd will not work directly on a directory per se. Technically dd can be used on single files, but that's a rather difficult way of going about things. To clarify: Using dd on a single directory, that dire

Just a quick worklog to give an idea of how you set this up and how it works. Of course, you may want todo things a little differently. It depends on if you want to keep the cloud9 directory "updated" Meaning over time maybe updates have updated the files, so perhaps one could make a fresh img file

[beagleboard] A question on automatically rebooting if BBB hangs

I'm looking at using a BBB in an embedded system. I have a 555 that I'm using as a watchdog which the BBB would reset every so many seconds. If a minute goes by and the 555 hasn't received a reset from the BBB then it would time out and send a signal (either high or low) to the BBB forcing it t

By the way Mark my last comment was directed at you. But one thing I forgot to mention is that once you unmount the tmpfs directory I mention above, the original directory would be there still. So you'd want to take steps to keep from overwriting files there. I mean you could technically just rever

Re: [beagleboard] Re: Debian Testing, un-root athon!!! (2017-04-18)

How about using a chroot ? Basically you keep a chroot image where ever you want, mount it where ever you want, and just wipe it out for a fresh start when you need to get back to pristine. I am trying to think what would be the smartest way to do this as you wouldn't necessarily want to spend a lo

Robert: It looks like all the files in */var/lib/cloud9/examples* are owned by *root:cloud9ide* and are mode 664. They need to be mode 665, or maybe 667. Mode 667 would let people easily edit the files and experiment. Though it would also let people mess up the files. How about we have a p

In the beaglebone, If the eMMC and sd_card do not have bootable media, the boot proces will go to UART device number 0 to look for a bootable medium and then to USB0. Meaning the device( some bootable device) which is connected to UART0 if UART0 is also not available then it will look for the devi

[beagleboard] Re: Understanding boot process of beaglebone black.

UART0 and USB0 are the peripheral communication. The number 0 attached to the end is the peripheral number, In modern day MPUs there will be multiple communication so we have multiple UART and USB. UART-0 and USB-0 are the first devices with the same protocol. UART-0 and USB-0 are the first in
