Topic: Is the Arduino Yun still Open Hardware? (Read 38314 times) previous topic - next topic

I think you can refer dragino ms14 for the wifi part schematic. this board uses same CPU, RAM, FLASH as Arudino Yun and the schematic is available at :http://www.dragino.com/downloads/index.php?dir=motherboards/ms14/


Thanks!

This is exactly what I am expecting to find for the Arduino Yun board.

I am still waiting for an official answer to my OP question, though.

The wiki.openwrt has poor informations about, but the most relevant thing is that it has a common jtag interface which i need for the most. Wandering where i can buy one of these unit, it seems interesting!

It looks like they have an online store:

Arduino is NO more opensource from Yun.

From the latest product, Yun, Arduino REFUSES providing EAGLE files (including hardware PCB,CAD files and the placement files) on the official website.
Arduino seems to try to become a company selling hardware all for profit.

The promises NO more extends:
"The boards can be built by hand or purchased preassembled; the software can be downloaded for free. The hardware reference designs (CAD files) are available under an open-source license, you are free to adapt them to your needs."

I arrived at the same conclusion :(

I don't have any problem with someone making money or selling a name, but I am concerned when you don't respect your promises and treat people like  cash providers and pretend to be community-driven.

Ok, so were are the schematics and layout for the Hornet (AR9331) MOST important parts?

Where are the schematics and layout in editable format? :smiley-mr-green:

What you ask is  QCA reference designs #AP121.

Sign NDA with QCA (Qualcomm Atheros) to get all the support, and you need  RF and Embed as well Linux engineer on staff.

I'm concerned with Arduino being open or not.
I on the other hand don't understand the importance of AR9331 being open. Are the AVR chips open? I guess not (I really don't know)
For me Arduino is open if they tell you which components they use and how they are being used. It does not mean they have to use all open components (I assume they never did)

Or am I missing something?

To sonnyyu,
As promised, "The hardware reference designs (CAD files) are available under an open-source license, you are free to adapt them to your needs." I was expecting the .brd or .sch files which could be "adapted."

On the other hand, so Arduino is sort of NDA products? "Non-Disclosure Agreement"
Then the word "opensource" should not be arbitrarily used.
That is no more than fraud.

No, I don't want to sign no agreement, and especially a non-disclosure agreement for accessing what is supposed to be an open-hardware product!

I don't need no staff either: I am an engineer, I know RF enough to be dangerous (Spectrum analyzer, VNA and understanding of RF ART calibration), I work under Linux for 20 years and for about 10 years on Embedded Linux and/or microcontroller stuff, with active participation to OpenWrt and Linux kernel by porting it to half a dozen of routers and stuff in the MTD driver.

See my reverse engineering of the AR9331-based TL-WR703N router.

I am concerned too, as this Yun board is clearly a major change in the Arduino policy. The AVR is a chip that you can buy and with a public datasheet to play with. The AR9331 has no public datasheet, and even the schematics containing the required components to make it work is under NDA, and you can't buy as retail, although you find many brokers in China (even for very low quantities).

So no, Arduino no longer tells you all the components they use, and they now use components with no public information on them, even the reference design on how to use them, thus my OP.

I completely agree with you: I have no problem with people making money or closed hardware, but advertising the Yun as Open Hardware is a lie, and this attitude is new to Arduino.

What I would like is a PUBLIC statement from the Arduino team that the Yun contains proprietary and/or non-disclosed materials that prevent you from adapting the board to your needs, even if the excuse for such change is to try to bring more power to the user, as this comes to the expense of freedom.

Thank you!

However, I'd prefer to have the information available in the first place to save me all this RE work. And this is why I am trying at least to get this information into projects for the Open Hardware community like the Arduino one.

BTW, do you know someone official from the Arduino Team that would be able to address this above concern?

I wish I know. Federico Fissore from team time to time post here and hope he will address this issue.

Why not ask Massimo himself?
