How would one clone a BeagleBone?

tl;dr: Assuming I'd had a BeagleBone perfectly manufactured from the open-source schematics+layouts, what would be necessary to get it to the same level of functionality as a newly-unboxed BeagleBone? Alternatively, how would one unbrick a…

How to use the BeagleBone's PRU with a modern kernel?

I am trying to implement a basic LED blinking program on the PRU. Up till now what I found are guidelines for old kernel versions (old in the sense 3.8 to 4.4 kernel version). Details of my BeagleBone Green: cat /etc/dogtag BeagleBoard.org Debian…

Yet Another question on using GPIO to short a remote push button

OK, I bought this little remote-controlled Ac outlet thing for $1. It controls 3 outlets via RF. I didn't realize it was RF at first, but I currently have my BeagleBone Black doing a bunch of home automation stuff on my network anyway, and figure…

CAN bus traffic is destroyed for unknown reason

I am a bit stuck with connecting several STM32F405 with BeagleBone black via CAN bus. Strange things happen when I connect 3 stm32 and 1 BB. I have checked that BB works perfectly with any combination of two STM32 devices. However after connecting…

How does this battery protection IC prevent overcharge/overdischarge?

As I was trying to understand how BeagleBone Blue is handling battery management, I encountered a battery protection IC (S-8261). How does S8261 prevents overcharging and overdischarge? (ELI5) BQ29209 and MP2615 also have overcharge and discharge…

Beagle bone black PRU program using DDR3 RAM

Could the beagle bone black receive input data from GPIO pins using PRU and then write it on the DDR3 RAM? It's known that you could use shared memory for this. But I wonder if it is also possible to use the 512MB DDR3 RAM. (I assumed rev C)

A protecting circuit using GPIO of the BeagleBone (Black or Green)

I'm really trying to develop a cape since I need to use 7-8 GPIO-Pins of my BBB Green and Black as Output. I'm too afraid to destroy the board somehow, so I was thinking to implement a solution which let me operate my board under safety condition…

Determine when Beaglebone has shut down (we we know when it's safe to cut the power)

As I understand, like most Linux systems, it's not recommended to simply pull the power from Beaglebone. Instead we should shut it down, either by pressing the power button or running a Linux command. Next we need to wait for a bit before…

Why can't the bootloader save and log messages for us to view later

I have a problem whereby a remote BeagleBone device is taking hours to boot up. When it does, I don't see any problems in the kernel boot logs such as journalctl -b or journalctl -b -1 Without having physical access to the device over the serial…

Is 1.8V UART compatible with Beaglebone Black?

I want to use a 1.8V UART cable with my Beaglebone Black? Is it possible as typically the Beaglebone supports 3.3V UART level. I am aware that I can use a level shifter for this purpose, but my application needs minimal circuitry and I don't want to…

Use BBB analog inputs with 0..5V or 0..10V

I plan to use the BeagleBone Black analog inputs for sampling of analog data. But there are some major problems for this: BBB allows a maximum of 1.8 V analog input voltage while I have 5 V or 10 V max there are two lines AGND and VDD_ADC where I…
