Hi!
Actually socfpga board folder includes code to support both Cyclone V and Arria V soc dev kit.
ok. I expect that you are talking about 2 completely different boards which are here
http://www.altera.com/products/devkits/altera/kit-cyclone-v-soc.html http://www.altera.com/products/devkits/altera/kit-arria-v-soc.html
Can you use the same configuration on both of them at the same time? I hardly believe that everything just match.
Actually, there's third board, called SoCrates, and yes, exactly same configuration works on it and cyclone-v.
What about Arria-V?
So you better start believing :-).
Maybe I will start to believe that Altera design all board the same like position of pins for uarts, spi, ethernet, etc.
At least Sockit and Socrates are pretty similar in that regard. Apart from the things that are not ;-)
Take for example the DDR3 pins on the FPGA side. The Sockit has DDR3-RAM, the Socrates hasn't. So, the pinsetup is different for both. And when you mess that up in the prebootloader, you can't AFAIK change that later. The boards will boot just fine with the same barebox image, but that doesn't mean, that everything is setup correctly.
That is what I meant -- you still have useful box running Linux. Having something useful that boots out of the box is important.
And it seems to be same(-enough) between Socrates and Arria, too.
