RPi CM3 and the Gumstix Geppetto boards

Scott Ellis
Just an FYI, I tested some new quad-core CM3s I just received with the Gumstix
Geppetto designed expansion boards

  https://store.gumstix.com/expansion/gumstix-pi-compute-dev-board.html

and

  https://store.gumstix.com/raspberry-pi-cm-fast-flash.html

and they work great.

I have notes for working with the Gumstix boards and the CM3 here

  http://www.jumpnowtek.com/rpi/Working-with-the-Gumstix-Pi-Dev-board.html

And notes for building  the O/S with Yocto here

  http://www.jumpnowtek.com/rpi/Raspberry-Pi-Systems-with-Yocto.html

I'm sure the Buildroot systems described here will work as well. I just didn't try yet.

I'm waiting on this new Gumstix RPi board to try out

Hi Scott,

Glad to see you're having the same luck with RPCM3 as I did (https://gumstixgadgets.blogspot.ca/2017/03/gumstix-pi-compute-boards-are-cm3-ready.html).  As always, the resources you provide are fantastic.

Thanks Keith.

I tried out the Gumstix Pi Compute USB-Ethernet board and that
worked fine.

I used one of my Buildroot built images

While ethernet is a very useful addition to the CM3 expansion boards,
I would have preferred that the additional pins available from the CM3
were brought out to a header as well.
