What's your progress with the SAMA5D4?

Jan Cumps over 9 years ago

Fellow contenders, how far did you get with the Atmel SMART SAMA5D4 Xplained Ultra board?

What are you going to do with this kit in your project?

Have you been able to use it for your Enchanted Object?

I have spent many many hours on that board. In the end I could build and cross-build bare metal and linux programs in C++ on it. But given that I already had those skills before I started with the SAMA5D4…

It's still in the box, it's a bit big for my project.

I'm making slow progress getting the toolchain working on the Yun, simply in order to get python requests[security] installed I've needed gcc, as, make, perl, bintools and ldconfig. Progress described below.

Just worked through the Perl modules which are needed to configure OpenSSL and onto "make depend".

So I should be able to help out with issues of tracking down tool-chain dependencies and the like.

I have not done much. I tried to mount the root file system through NFS which did not work. Either the kernel has no NFS or network drivers compiled in. I did not debug that. NFS works when booted with the rootfs on the flash. Next step will be installing node.js / io.js. I reduced my requirements to node.js + linux + I2C drivers. This should be possible.

Have you fired up one of the boards? I gave mine to a Linux expert who likes a challenge.

At least he's going to give it a try rather than it sitting in my drawer. He already knew about the Yocto project so I guess he knows more than I do.

I have spent many many hours on that board.
In the end I could build and cross-build bare metal and linux programs in C++ on it.
But given that I already had those skills before I started with the SAMA5D4, it should have taken me maximum a week, not the 3 months that I invested in it.

I still think it is a great board. The doco wasn't good enough when we started, but improved very well. But the support community isn't one I'd like to use any more in my future life. I'm not sure if Atmel realises what impact some of the participants have on your enthusiasm to give the board a go.
I'm still recovering from the experience

I looked at Yocto and found it is more a method than a cure. If he does find the key, please share with me so I can sleep better at night.
