Banana pi BPI-M2 Ultra quad core single-board computer with allwinner R40/V40 design

looks like built in storage and SATA support is the new norm - good work :slight_smile:

Hello, what is the clock speed of the R40 SoC? Thanks.

R40 datasheet:

axp221s datasheet:

Thank you for answering. Do you already have this board price? Thanks

about 35-40 USD . we need do the first 5K ,and know mass production cost

Looks like an nice board, can you specify the delivery date? is empty?

Same with When do you deliver?

When will you release schematics? Care to answer?

  • Where is the 3rd USB host port?
  • How is ‘SATA Power’ wired? From PMIC or directly from DC? Is a connected disk powered when running on battery or not?
  • When do you release schematics?
  • Care to hire someone who is able to write technical documentation? is a joke isn’t it? No real information and the few sentences are wrong (you can’t power 3.5" disks from the board since 12V are needed)

Is this normal? Not answering the most simple questions? When do you release schematics?!

Banana PI BPI-M2 Ultra is the open source hardware platform

Do you know what open source hardware means? Obviously not when you not even manage to release schematics timely.

One last time: When do you will release schematics or at least answer customer questions like the above?

yes , we will open schematics. will update to gitbook.

I’ve been looking around for android, and raspbian images for the M2 ultra, but I haven’t found anything. Are they still being worked on, or is there somewhere I can get them?

allwinner R40 chip and V40 chip is PIN to PIN compatibility, so BPI-M2 Ultra just replace V40 chip onboard, easy to DIY and do a new product

Can you please briefly designate the differences between R40 and V40 chips?

same chip , just remark , and allwinner support different SDK , .

Any idea where to find a case for the BPI-M2U?

I’ve been looking in the UK (Amazon, eBay) and across the US and I can’t find a case that specifically mentions the M2U.

Or should the M2U board be compatible with any of the other boards in terms of fitting in a case? Cases for the original Banana Pi don’t quite fit.

Suggestions please!

Hello everyone, I purchased a BPI M2U in Taiwan about 3 weeks ago and have been slowly getting around to putting it in operation as I found my previous experience with a Cubieboard1 a bit challenging. In that case, I had to do a complete compile from scratch and install both U-Boot and the Linux image.

From what I can see, the Banana Pi M2U arrived without U-Boot or Linux installed, so I am wondering again what to exactly do.

I have located and downloaded a Linux “raw image”, but Banana Pi doesn’t offer any suggestion of how I should ‘dd’ the image to a microSDcard (class 10 or better). I can try doing what worked with the Cubieboard or what may have worked with another Banana Pi board, but it certainly would be nice to verify that the process is identical.

I presume the absence of U-Boot because the serial port at baud 115200 does not do anything in Putty, whereas I get U-Boot reports in Cubieboard even when I don’t have and microSDcard inserted.

But I do find it a bit annoying that BananaPi doesn’t have anything to say about the need to or the lack of need to install U-Boot.

++++++++++++++ In short, for each and every version of the Banana Pi, it would be extremely helpful if you provided the basics of getting an operating system up and running. Each seems to require its own recompile of U-Boot and Linux. Sunxi-Allwinner is very helpful, but many new users either would not go there or become lost in the added depth of technical info.

I’d really hate to install the wrong version of U-Boot and do significant damage to a new board. That’s why I turn to you for guidance.
