Getting to know your BeagleBone with Jason Kridner

Bi-Weekly webinar series with BeagleBone Co-founder Jason Kridner.

Each webinar has an accompanying demonstration video.

Jason will also take questions posted in the discussion below.

Session 2: BeagleBone for Linux Users

Jason introduces you to Linux for BeagleBone and fields your questions.

In this session we will be covering topics such as, which Linux Distros are available for BeagleBone and which are preferred. Which programming languages are compatible and their notable use cases.

This week’s accompanying demonstration video.

- Installing Debian

- Interacting with GPIO in Debian

- Interacting with PRUs in Debian

Questions

Please post your questions for Jason in the comment section below.

Accessing the Webinar

Webex has an official ‘supported system requirements’ available here:
- https://www.webex.co.uk/support/support-system-requirements.html
- Linux:
  - No webcam transmit support (only view)
  - No video file sharing support
  - For Browser based, only Firefox is supported
- Mac:
  - No USB headset support
  - No Animations/transition support for presentations

There are Android and iOS clients:
- https://play.google.com/store/apps/details?id=com.cisco.webex.meetings&hl=en_GB
- https://itunes.apple.com/gb/app/cisco-webex-meetings/id298844386?mt=8
It should be possible to also ‘dial in’ using the computer as opposed to a phone line. You will need to download and install a plugin for this:
- http://fh1.westuc.com/downloads/rpvoip.exe for windows
- http://fh1.westuc.com/downloads/rpvoip_mac.pkg for mac

For the question of "How to copy from emmc to SDCard to another BeagleBone's eMMC Jason offers the following advice using the script available here on the beaglebone and then from github:

/opt/scripts/tools/eMMC/beaglebone-black-make-microSD-flasher-from-eMMC.sh

https://github.com/RobertCNelson/boot-scripts/blob/master/tools/eMMC/beaglebone-black-make-microSD-flasher-from-eMMC.sh

Derek Molloy's "Exploring Beaglebone Black" is still one of the must have books for working with the Beagle. However, since the OS was changed to deal with I/O some of what is in all 7 books I own suddenly became worthless. You can't just cat $SLOTS anymore to find out what's installed. It's still possible to create a custom cape and identify it in the EEROM but you have to go online to get current information and potentially be called stupid by one of the many forum 'experts' who will tell you that question has already been answered.

Another great cape for CNC control would be this one. https://www.pmdx.com/PMDX-432 But as the description states, there's no support because there's just no money in it. Yet plugged into the PMDX-126 you end up with a complete CNC Milling Machine controller with isolated inputs and relays for controlling spindle and coolant. Just add motor drivers, switches and power supply (and a mill). But to get the PMDX-432 you now need to set up to order at least 5. I have the Xylotex BBB-DB25/26 (also discontinued which seems to be a trend for BBB capes). I'm plugging that into the PMDX-126 to run my mill. But I have a couple of PCs I picked up for $25 each and video cards for $15 as a LinuxCNC fallback in case MachineKit on the BBB is unworkable.

I have 3 BBBs and a number of Capes including the RepliCape and the Manga screen. I have 4 Raspberry Pi's and given a choice unless I need CAN bus or want to use it for CNC I still find the Pi easier to use and the community far friendlier when there is a problem. And I can't figure out why.

And yet I'm not giving up. And I can't figure out why...

That sums up my problems pretty closely. There are so many examples online referring to $SLOTS which is not a lot of help if you want to keep moving with later distros.

Missed the webex but will grab the video. Really looking forward to some fresh info on how to untangle the Pin muxing and PRUs specifically.

To all members and attendees. Just a passing thought here: Linux seems like a big topic. combining Linux and Beaglebone together for a 45-minute webinar seems like a huge topic to cover. Here's my suggestion…
