This is probably a repackaged version of the A83T die, maybe with some
features disabled. The A83T, H8, and R58 all have the same specs and
packaging.

The user manual says PowerVR SGX544MP1.

Nope, this device is completely useless (at least for me). I already
finished my "review" (a severe warning regarding the board's manufacturer
combined with a few technical details I was able to collect).

http://forum.armbian.com/index.php/topic/474-quick-review-of-banana-pi-m3/

I will keep it the next 2 weeks but then it's free for anyone working on
A83T. Just drop me a note. Preferably from within Europe due to shipping
costs.

But if I understand correctly, A83T is already gone and replaced by 'R58'
instead? http://www.allwinnertech.com/uploads/150529/7-1505291G22Y25.jpg

Anyway, @Vishnu, can you please comment on the question whether the A83T
contains a SGX544MP1 or MP2? According to the fex files used for the
BPi-M3 it should be 2 CPU cores.

Thx,

Thomas

Keep it, you're doing good work.

[linux-sunxi] Banana Pi M3 (A83T based) soon ready to donate

[Thomas Kaiser]

Hi,

anyone interested in one of SinoVoip's Banana Pi M3 to improve A83T
support?

I've been selected to receive a free sample by SinoVoip due to being their
most active forum member (a bit weird since most of the times I advise
there against choosing SinoVoip products due to worst software/support
possible :-) and still can't believe that instead of sending a contract
killer to my address they obviously shipped the board instead:

https://nolp.dhl.de/nextt-online-public/set_identcodes.do?idc=7214605425

I'll take some pictures for our wiki, fill in informations there, provide
a working Debian image and a set of tools to combine any rootfs with
bootloader/kernel (none of the few linux images SinoVoip provides for
download currently work since they're all corrupted... and they ship the
devices without eMMC being populated) and write a review of the board.
Will take approx. 2 weeks counting from the board's arrival ‹ see tracking
URL above if you apply.

Then I'm done with it and would love to send the board to someone else
working on A83T who has a better use for it than me (don't need it, A20
still the best due to SATA even if it's slow for unknown reasons :-)

Thx, Thomas

Thx, but I don't have any use for such a device (lacks I/O bandwidth
compared to processing power). The only thing I'm really curious about
A83T is the performance. Allwinner's weird press-release is still online:

http://www.allwinnertech.com/en/news/compnews/452.html

It can't be big.LITTLE, just little.LITTLE with 2 x A7 quad-core clusters
each. And I really doubt that the "around 2.0GHz" claim is true (TBC).

Anyway: Since some of us are working on A83T and I have no use for this
board after I'm done testing it, I still want to donate it. Preferably to
some of you devs that aren't focused solely on mainline since most of the
problems unfortunate BPi-M3 customers will run into might be solveable
easily by tweaking rotten 3.4.39 stuff (had a first look into it today ‹
woohoo!)
