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
