LED test board for Hikey

tony_zhang

I upload a video on the Facebook.
In the video, we test a led board with usb debug uart on HiKey LS connector. The mainly function is to test the GPIO function for all the pins on the LS connector. Also we can use it to debug the low-level driver.

The link is here：

And also the hikey is coming soon, every one who want to have one can see here to pre-order it:

Great! I like it!

Tony,

The HiKey looks very interesting, but it desperately needs a GPIO breakout at 3v3, something like the BaseBoard for the Guitar.

Best Regards,

Bill

Because the Kirin 620 output is 1.8V, and the 96boards specification limit the board size, so it is hard to add to much power level shift on the board itself.

Why? Have you ever had a look at what to expect from this 96boards initiative and the specific SoC in question?

Why using an octa-core CPU without any external I/O bandwidth/connectivity? What's the use case? I'm really interested in your findings since apart from a certain level of hype generated around 96boards I see nothing interesting at all (since there exists not a single 96board that is compliant to their own specs regarding software support).

LOL! Just had to realise that LeMaker only concentrates on hot stuff in the meantime: The HiKey can not be operated at maximum clockspeed due to thermal issues. Too funny: https://www.96boards.org/forums/topic/maximum-cpu-temperature/

Of course I know the issue. If you have more deep investigation, you will know the Kirin 620 is original applied on mobile phone. The same situation the Drango Board 410c faced.
The main strenghth the Hikey is the ararch 64 development platform.

I know that the Kirin and the Snapdragon 410 used on the Dragonboard are SoCs for mobile phones and not suited for SBC useage. Again: Why should I have a look at any of these 96boards (when I don't work for/with Linaro and MUST support them)?

I don't want to deal with UEFI/GRUB on any ARM board -- that's just weird.

If I want to start with AArch64/arm64 development boards I order a Pine64 for $15 or something based on Rockchip like the Geekbox for example.

I can only say everybody has his own taste. Impossible to satisfy everyone.
