[BeagleBone Black] Enable All UART Ports at Boot

Previously we used enable the UART ports by hand, but that’s annoying because it required doing it manually every time the BBB boot. In addition, writing a script wouldn’t work for some reason. For my quadcopter project, the BBB must enable all UART ports by itself at boot, since I can’t fly with a wire hooked onto it. Therefore, I went on and do some digging on this… took a while before anything came up. It’s actually more complicated than I though, having to deal with how device tree works and all… but here’s what I found:

[BeagleBone Black] Launch Python Script at Boot like Arduino Sketch

In order to use the BealgeBone Black as a flight computer or embedded system in a product, it must be able to launch programs we wrote on start up without having to manually start it after logging in via ssh. Something sweet and simple like an Arduino, when it start, it run the program you put on it. I spent days looking for ways to do this, editing init.d and all, none of them work. And finally, I came across this blog for Raspberry Pi and work perfectly!

So to be sure that the script is running without logging in through the computer, I decided to do a “blink” loop like what we do when we first started Arduino.

[BeagleBone Black] Enable USB Internet Sharing from Windows

Now that we boot Debian fromĀ a MicroSD card and expand its file system capacity, the final step to complete setting up is to share Internet from my main computer. I got a windows computer, so I will do it from there. Instruction to other platforms should be similar.

If you rather watch a video, I pretty much follow this video, it helps a lot! I really need to thanks the people (in this case a professor) who share their knowledge for the good of everyone!

[BeagleBone Black] Expand File System Capacity on the MicroSD

In the previous section, we set up the BeagleBone Black Rev B to boot Debian OS off an MicroSD card. Here, we are going to expand the storage capacity in order to update the software and install apps.

Pretty much, I followed the instruction on the eLinux website, and it works perfectly! So you can read the details there, I will list the basic steps here.

[BeagleBone Black] Boot Debian OS from Image

The BeagleBone Black (BBB) is an awesome little micro-computer. When compared to the Arduino, it is more capable in that it run Linux and support many of the awesome software out there… that also means it’s more difficult to set up.

I found myself always going back to the sources to see how to set things up. Therefore, I figure I might just be a bit more organize and consolidate the information here. Since I have a PC, the following instructions will be for Windows, but I am pretty sure the procedures are similar.
