Does the raspberry pi and its accessories meet free software/hardware standards?

Wait, I found this.

"16.2 Recent Broadcom Chipset
The Linux kernel comes with the brcm80211 driver by default. This driver supports bcm4313, bcm43224, bcm43224, bcm43225, bcm4329, bcm4330, bcm4334, bcm43241, bcm43235 (>= rev 3), bcm43236 (>= rev 3), bcm43238 (>= rev 3), bcm43143, bcm43242." - http://www.opensuse-guide.org/wlan.php

The raspberry pi wifi dongle has the BCM43143 chipset so it should work, right?

Maybe this will help?

The documentation of non-free distros will only confuse as they use Linux. (which contains blobs)

I'm not sure but I think the non-ancient broadcoms will not work.

Besides that you can't even boot the rasp pi in freedom. https://www.fsf.org/resources/hw/single-board-computers

The official distro, Raspbian, comes with many proprietary programs by default. Mathmatica, Wolfram Alpha, Java (Not the free version, IcedTea,) and Minecraft. There may be more that I'm not aware of.

That doesn't even count the proprietary firmware on it that lembas mentioned.

Got a question. I am teaching programming on schools (age 7-11). Up until now I had been using the computers available on the schools but now I was asked by a school to form a complete program. The school was thinking about ipads....

Using this article ( http://www.fastcodesign.com/3051347/why-ipads-and-chromebooks-wont-save-the-classroom ) as an inspiration I convinced the head of the school that this was not a good idea. Now I would have loved to use only free software, but the school did not want to replace all their computers with Trisquel (yet!). I came up with the idea of purchasing 20 Pi's and a couple of second hand monitors and keyboards. I am aware of the problems with the Pi's but I think this is a reasonable start. During my presentations and lessons I incorporate as much free software/FSF/GPL as possible. We use Libreoffice, Scratch and Python at the moment. Also, the fact we can use the Pi for other projects like attaching LED's/motors is a big plus.

My question, what do you guys and girls think? What would be the best way to teach programming on schools? I have more schools interested in this way of working and I think teaching the way of Free Software at those schools is a great way to raise awareness with kids.

I would love to hear your thoughts!

Wifi is one thing. You can probably find some USB wifi stick compatible with free software, such as the ones supported by the ath9k_htc driver. They have a free firmware.
Thinkpenguin sell some. In fact they were involved in its liberation.

However how good is a board if it cannot even boot with free software.
As I understand it the rasberry pi 1 has a non-free GPU firmware that is required to boot: it initializes the RAM.
As I understand, part of it of it was published as free software, but not the RAM initialization part. I'm not up to date with the status on the work to replace it.

I guess it's worse with the rasberry pi 2 because I didn't heard yet of the source code of the rasberry pi GPU firmware being published.

However there are many boards that can boot with free software.
On non-x86 devices, the bootloader usually does the job that GRUB and the BIOS do on x86. You also have many free bootloaders for non-x86 (u-boot, barebox, redboot, pmon, and so on).

So just pick some other board like the beaglebone black instead. Parabola even supports some of them, so check with parabola instead.

The pi sucks for freedom because the makers aren't concerned. You'd be better off with the suggested beaglebone or the novena.

Thanks for the suggestion. I own a BBB so I'll have a look at it (the parabola stuff), only thing that could be a potential problem is the price. People know of the Pi so if I suggest an "expensive version of the Pi" (if you know what I am saying) I must have a good story. Free software is usually lower on the list than budget for schools....But I can try.

I do spend some time talking about the FSF / GNU and the virtues of using free software to the kids. It will be just a matter of time before one finds out the Pi isn't exactly fsf friendly, but I think it is a step in the right direction. At least I talked the school out of buying 30 ipads...

By the way , the kids absolutely LOVE working with the Pi and Scratch, which is the first programming thing we are looking at. They think it is pretty cool to work with such a small device.

Teaching free software one step at a time, better then nothing I suppose....

The Raspberry Pi Foundation have little interest in supporting free software
beyond being able to create a custom OS with ease. Their commitment to 'open
source' seems to be a PR exercise. I discovered this when I decided I wanted
to have a different GNU/Linux distribution to the crippled 'Rasbian'
distribution, because at that time it was poorly optimised. The Rasbian
distribution also includes several non-free programs such as Wolfram Math and
a port of Minecraft. Therefore, the Raspberry Pi really does not teach people
about freedom, just convenience. Reading the forums, they clearly just don't
care about projects such as Das U-Boot, and most 'mainstream' distributions
don't support the Raspberry Pi because it uses an uncommon CPU architecture
and requires the bootloader blob to initialise the entire system. 3D
acceleration is also nearly impossible with free software, although I heard
that work is being completed for support in upstream Linux 4.5 (which itself
has issues). The Raspberry Pi therefore is nowhere near being free hardware,
and there is little commitment to free software.

The official distro, Raspbian, comes with many proprietary programs by
default. Mathmatica, Wolfram Alpha, Java (Not the free version, IcedTea,) and
Minecraft. There may be more that I'm not aware of.
