Another Allwinner board dropped

 

figuring out the wifi chip is always hard, seem to be

as usual, it is uncertain if drivers and firmware is after all available.

 

Ethernet according to CNX seemed to be YT8531CA 
Ethernet seemed to be same as that in OrangePi Zero 3

WiFi is 'more critical' these days, if it is closed sourced and no firmware, then it is good as just a door stop.

Then that thare are other stuff the figure out especially the :

- DRAM controller,

- and various DRAM timing and configuration aspects

- many other low level specific stuff to even have u-boot to boot it up to the linux prompt.

- then the other devices e.g. uart etc. 

- then HDMI

- then gpu acceleration (or at least display video, not playing media yet)

- then media 

- and finally NPU, don't seemed documented yet

- many more known or unknown unknowns, audio etc

It seems the Ethernet dirver is already in mainline, and oss wifi driver are available:

I really hope that Armbian will be released soon for this board. I have it, but the official ISO has an old kernel and no RT capability.

 

[Ivan Habl]

I also hope Armbian will support this board, as it offers a very good price-to-performance ratio.

We don't have intention to support this board without funding. However anyone from the community can step up and add support for it.

I really hope that Orange Pi engineers learn to make Armbian patches, enter the community and give funding accordingly

I like your kind of humor

psst, I ordered a board, hopefully I've time and may get it going

it takes a lot of *work* to even get it working and with more often than not , no (scant) documentation (e.g. missing dram controller docs ) / codes to even get it working.

btw it is good for those who wish to have board support to donate in support of armbian in support of it, it is probably the only sustainable way to do so.
