HW initial review



After the initial yay! moment I have some criticism

  1. The screen scratches like… really easy… I have it one day and it’s nasty already (had to open it up at least twice)
  2. The controller is a keyboard?.. why??
  3. The controller buttons are sticky because the tiny holes in the inner box are too close to the button size
  4. The SD card slot placement is terrible
  5. Not really hw… but please give us access to the GPU… some instructions to build the drivers at the very least

I love the modular aspect, but if I was going for a v2 I’d do the following:

  1. Keypad would be a HID device
  2. Keypad would be a fully built controller from the get-go, people like modularity because they may be able to upgrade the SoC or the screen, but the controller is likely to stay untouched. As an alternative, sell fully built controllers that fit in the space
  3. Ship more than one screen tray? ship a screen protector I guess? use corning gorilla glass for the screen tray?


For “screen scratch” I’m quite sure there is a protective screen on the plastic. Are you sure to have removed it?

Sound stupid but I seen lots of people complaining on device that the screen had scratches when in fact the scratches was on the protective film they didn’t remove… :sweat_smile:

For the GPU it is not CPI fault, if you want drivers go and ask Allwinner or ARM…


No the cover is not what got scratched, it’s the plastic case for the display.
Uh, there are drivers out already, you just have to build the kernel and the drivers whichi is no trivial task



Compatibility and/or price, most likely.

Mali400 on sunxi is mainlined, the blobs are publicly available, as is the xorg driver. I plan on implementing it as soon as I get my gameshell.


Bootlin also released an open source VPU driver, but mainly for video decoding. Not sure if it has any use for GS, but the R16 is supported: https://www.cnx-software.com/2018/07/23/open-source-vpu-driver-allwinner-mpeg2-h-264-video-decoding/


If you want to play h264 videos on a 320x240 screen… :sweat_smile:


Haha well maybe for the next version if it includes HDMI out :stuck_out_tongue:


Did you ever compile these drivers for this hardware and get it working? Im curious if how much performance improvement we would get over the open source lima driver that is being used now. I may attempt to try it myself, but figured I would ask first.
