Hi guys

 

I can't find a forum for SAM or embedded linux, that's why I post this question here.

 

I want to play around with embedded linux, and I found that this website (Linux4SAM Getting started) has the most comprehensive documents I can find on embedded linux. So I want to buy a board to play with. They have a few boards listed on the website, and I am not sure which one to buy.

 

SAMA5D2 Xplained

SAMA5D3 Xplained

SAMA5D4 Xplained

SAM9

 

I was thinking to get the SAMA5D2, but it's not listed on the getting started page (only on the side bar). That makes me thinks it's not getting as much support as the other boards?? I want to get a board with the best support/documents, but also as low coast as possilbe. (As I am paying it with my own money)

 

Thanks guys!

Why would you want to use a sama5 series device? For much less money you can buy boards like the beaglebone black, raspberry pi etc that have more performance to boot.

Industrial temperature range ... though there's an exception for BeagleBone Black :

P.S.

Olimex has added a few industrial ARM9 (ARMv5) boards :

The local ad for (embedded) ee usually mention experience with linux in AVR (assuming sama5 series). If spending one or two hundreds more can make me more competitive, I think it's worth it in the long run. Assuming my logic is true in the eyes of future employers. This is my main motivation. I would love to hear others opinions on this tho. 

The second reason is the documentation I see on the website I linked in, I like good documentation. (Although the documentations linked in by gchapman looks pretty good too).

The AVRs that run linux are obsolete. So scratch that idea. Linux is linux, so whether is is running on a wireless router, your PC or anything in between, its all much the same. You said you wanted cheap. If samA5 is flavour of the month, then next month it might be nxp's new product that's recently released.

Another industrial ARMv7-A in SoM form instead of a single board computer :

Debian Linux distribution is officially distributed, but recent patch add support for AM3352-SOM in Beaglebone kernel
