Loki Update

Update 1:

Loki Max PCB Board -- 2022/9/6

 

Update 2 --2022/9/30

Since we got the 6800u/6600u board weeks ago, we have been working on all kinds of tests the whole time. There are a lot of progresses achieved which keep moving this project going ahead steadily. Let me share the detailed updates sorted by skus:

 

Progress for Loki/Loki max

Tested items (worked fine):

  • LPDDR5 8G/16G
  • SATA & NVMe
  • TypeC (DP/USB3/Charging)
  • USB 4.0 20G
  • Controllers ( Powerbutton, Audio rocker, Joystick/Dpad/ABXY/L1R1/L2R2, ... )
  • WiFi-6 + BT
  • Audio Jack and Speaker
  • Micro SD card
  • CPU Fan and power LED indicators

 

Ongoing items(Not finalized):

  • Heatpipe for aging and stress test
  • eDP & touch
  • Vibration motor
  • Ambient LEDs
  • Screen

 

We would like to share more details about the screen. We have been working on driving eDP port to MiPi for a while. Now this screen works in MiPi video mode, while AMD 6800u doesn't have MiPi port available, so we added a bridge chip to drive this screen from AMD 6800u eDP port. We are very close to solve this issue.

 

Progress for Loki zero

Tested items (worked fine):

  • DDR4 Onboard and SODIMM    
  • eMMC onboard and SATA & NVMe  
  • TypeC (DP/USB3/Charging)
  • Controllers
  • WiFi-5+ BT
  • Audio Jack and Speaker
  • Micro SD card
  • CPU Fan and power LED indicators

 

Ongoing items(Not finalized):

  • Heatpipe for aging and stress test
  • eDP & touch
  • Vibration motor
  • Ambient LEDs
  • Screen

 

Update 3 --2022/10/29

First, after weeks of so much design and verification efforts, this adpter chip finally works, and the dream to keep it less power consuming than competitor's solution finally comes true.

Second, we are finally make Loki screen that works perfectly, and what's more, thanks to the FPGA working as a featured Aux-channel protocol manager, we make this screen worked in 60/50/40Hz refresh mode, which was requested by so many existing Loki buyers for the consideration that to reduce the cpu/gpu load of 2d/3d rendering significantly, and thus to extend the battery life by a great amount of time.

Third, the further good news is, we can even make custom resolution work at 60/50/40Hz mode, and with the help of multiple frame rate, the rendering workload can be further reduced by setting the frame rate lower(50Hz/40Hz).

For example, if we choose custom resolution to be 800*600@40fps, then the overall workload is 800*600*40/1080*1920*60 = 15.4%, that means, all the rendering pixels in this case can be 15.4% of 1080p60, and literally the battery power might be able to be extended by 5~6x longer, that should be a huge improvements.
