Pharo for Raspberry Pi

I'm following Torsten's article, "Pharo Pi," to setup my new Raspberry Pi 3. The only differences are: 1) I'm using 63.zip for the VM instead of 61.zip; 2) I'm using Pharo V50 instead of V40. However, I'm getting the following error when I try to run Pharo:

This interpreter (vers. 6505) cannot read image file (vers. 6521).

Any idea what's going on?

Re: Pharo for Raspberry Pi

I guess you will have to check both, the VM and the image are Spur or not. Do not combine them.

Okay, I had to fall back to V40 of Pharo. I guess that means I also have to fall back to the previous "Pharo by Example" book, instead of "Pharo by Example 50."

Bummer.

Hi richard,

Denis is working on a raspberry connexion.

He showed us that he can remotely control an arduino connected to a raspberry running Pharo.

I will demo it during Pharodays and we plan to produce a tutorial.

So you can beta test it.

btw, a good place to search is forum.world.st.

Here are the two best I found...

http://forum.world.st/ImageFormat-updates-tp4944966p4945730.html

http://forum.world.st/magic-decode-for-image-files-tp4941712p4941713.html

In summary, you are trying to open a Spur Image with a non-Spur VM .

Try a VM from... http://files.pharo.org/vm/pharo-spur32/linux/armv6/

and an image from... http://files.pharo.org/image/50/

Perhaps somewhere I saw that latest (i.e. 50772.zip) was made compatible with latest VM (??).

But see Tim's caution about a period to avoid of unstable VM...

The old PBE corresponds to Pharo 1.4.

As I remember, last time I used the standard squeak vm that is shipped with the rpi3, and it worked fine with Pharo. I don't remember whether it was a spur image or not, but it worth trying out.

This looks great !

I find the repo here: http://smalltalkhub.com/#!/~Pharo/IoT
I guess this is the correct repository ?
