Raspberry Pi

You cant use the repositories to install ignition on the RPi, you have to install manually from tar.gz. I recommend untarring them to /opt/ignition.

As for my write up, I’ve been absolutely swamped lately, so I have not had time. I am still going to get it done this month.

As previously stated, the RPi has an ARMv6 architecture, so it cant run headful using the Oracle binaries (so no client, only server). I have not tried openjdk, but I presume they would be the same. To get headful java from Oracle, you need an ARMv7 architecture. I have a few of the following boards on order.

Im hoping to get debian/ubuntu running on them, as those operating systems support ARMv7 architectures.

@Kyle,

Response appreciated! :prayer:
Please don’t rush the write up on my account.
I am going to switch gears with the Pi and just use it to play around with
Python and other hardware via the GPIO.
It appears fruitless that it will run a graphical client, which is fine. It can have other uses.
The client was what I was wanting to use it for (digital signage). It can do many other things
that I will take advantage of.
Thank you again for the response!

sounds like something useful lies ahead for the gooseberry!! :thumb_left:

[size=150]From the release notes…[/size]

JDK for Linux on ARM

This release includes support for a new platform, JDK for Linux on ARM. The product offers headful support for ARMv6 and ARMv7.

[color=#FF0000]No support is available for WebStart, Plug-In, Java Flight Recorder, and Garbage First (G1) Collector.[/color] Also some features of the Serviceability Agent are not available for Linux on ARM platform.


So, I’m guessing that lack of WebStart support may be an issue?

It means no launching off the gateway on that machine, but you can launch from a shell script or shortcut still.

Good 'nuff!

Looks like Ill be busy getting that writeup done. I have 1x Raspberry Pi, 2x ODROID-X and our dev board for our boxes. Ill try power through this, and include the shell script to launch the ignition client.

:thumb_left: very cool!

SPEAK OF THE DEVIL,

I have actually been playing around with the gooseberry this evening. Throwing my share of profanity
at it. I went through oracle’s big ‘survey’ to get to the download for the updated java. I am still in the terminal trying to get installed from tar file. On a disgruntled note, the download STILL SAYS headless for armv6. armv7 was headful… I could be wrong but I still do not believe this will work even with the update. Kyle Chase could chime in with his write up anytime. I am starting to realize I may be expecting too much from these little boards. all I really wanted to do was see ignition run and maybe use for digital signage. so far that has been completely BUNK… I have used it playing around with the gpio so it is not a total loss. for PI owners I think everyone should check out the digital magazine called MagPi. It has some really cool python and ‘C’ tutorials for novice programmers…

I didn’t see the arm version on the wiki for cubie. with some searching we could find out…
It seems to be very important. obviously the most important for oracle java to run.
I have also heard other reports of the ‘ice tea’ working for Ignition (somewhere on here).

Will keep an eye on the cubie…

For anyone with too much time on their hands - There’s a free online pi course.

Ive been checking for v6 support for headful java, no luck yet. Ive been too busy to do the raspberry pi stuff as of yet. But it is still in the plans, whenever I get spare time. Sorry for the delay,

Model B now ships with 512MB of RAM
Posted on October 15, 2012 by eben

Update: Those of you lucky enough to receive a 512MB Pi this morning can download updated firmware here. For example, download arm384_start.elf and rename it to start.elf on /boot partition. You will then have a 384M/128M memory split.

One of the most common suggestions we’ve heard since launch is that we should produce a more expensive “Model C” version of Raspberry Pi with extra RAM. This would be useful for people who want to use the Pi as a general-purpose computer, with multiple large applications running concurrently, and would enable some interesting embedded use cases (particularly using Java) which are slightly too heavyweight to fit comfortably in 256MB.

The downside of this suggestion for us is that we’re very attached to $35 as our highest price point. With this in mind, we’re pleased to announce that from today all Model B Raspberry Pis will ship with 512MB of RAM as standard. If you have an outstanding order with either distributor, you will receive the upgraded device in place of the 256MB version you ordered. Units should start arriving in customers’ hands today, and we will be making a firmware upgrade available in the next couple of days to enable access to the additional memory.

I’d like to thank our partners, RS Components and element14/Premier Farnell, and the suppliers, particularly Samsung, Sony and Broadcom, for all their help in delivering a smooth transition to the 512MB. I’m looking forward to seeing what you all get up to with your shiny new Pis.

Finally received mine! Alas, it does me no good, since I’ve had absolutely no time to do anything with it. :cry:

Same here! I got mine, set it up so that I could SSH into it, then… did nothing else! When all’s said and done, the Raspi is really only a cheap, low spec computer. Also, if you want to embed it in a project, you have to embed the whole board, rather than just one chip.

I would still be interested in a cheap view node for Ignition, but for small projects interfacing with the real world I find I’m going back to the Arduino.

I agree, there are some neat projects with the gpio on the pi though. Now that u have one I would recommend
a newsletter called the magpi. its a good read.

A Raspberry Pi is about the same price as an Ethernet shield right now. I think we’ll see a bunch of projects using an Arduino to extend the GPIO of the Raspberry Pi until it gets a little more umph under the hood.

I just bought a number of Arduino Ethernet shields on Ebay for about $11 - bargain! We’ve now got an Arduino working as a Modbus TCP slave, which is handy for testing.

My plan is to start simulating processes using some python magic, a RaspPi, and pyModbus. Can’t run Ignition efficiently yet, but that doesn’t mean I can’t use it. Interfacing with an Arduino for more GPIO means I can put meaningful buttons and potentiometers to control things.
