96boards?

So today Linaro announced their first board from 96boards project. It is named HiKey and is based on HiSilicon cpu for mobile phones.

I had an occasion to see that board during FOSDEM and decided to write something about it after it land on my desk (which will happen sooner or later). But I have read specification for this and next boards and decided to write few words from my perspective.

First thing? Footprint. Good that two sizes are available for designs as not everyone may want to squeeze into small one.

Second? Ports. 2015 year and no Ethernet, no SATA? Sure, first board is based on SoC from a mobile phone but there is no place on small board for them and extended version looks like not allow for extra ports too.

Next? Power supply. 8-18V in a world where everything is on 5V already. The only place where 12V is mentioned in spec is “external fan power”.

So as we are on voltage… Serial at pins and 1.8V level. Nice way of forcing everyone to buy new serial dongle (Arduino ones are 3.3 or 5V).

But assume that we got it powered and have serial connected. How to boot it? According to specs mainline kernel (or AOSP one or LTE one) has to be used. I wonder how HiSilicon cpu is supported in any of those. From what I read during day (on quite slow connection) it is still not in a kernel…

Graphics situation is still shitty. Vendor is allowed to provide binary blobs to get display working. Did they not learnt from OMAP? PowerVR again someone? But sure, plain framebuffer is all you need. OpenGL is for weak.

I prefer not to discuss about selection of signals on low/high connectors. There are more capable people for it. I only wonder why 2mm raster where nearly all boards I had played with had 2.500 one.

I like list of distributions listed as ones to choose. No longer Android/Ubuntu but also Debian, Fedora or OpenEmbedded based one

But give them time. It is just first board and next ones are announced. Marvell will produce one (they are in a Linaro group for it), other will (probably) follow. Hope that there will be something better.
