Retro Lite CM5: Alternate Mode over Type-C (DisplayPort)

A quick working example of an external USB-C PD controller implementation, with SuperSpeed mux flip and hotplug detect to negotiate alternate modes over Type-C - Armbian 23.11.1 with Radxa CM5 & RK3588S SoC. I used the TUSB546A and TPS65987D from Texas Instruments to get this working & will feature in the final CM5 build.

That's great! Out of interest, what display and driver board are you using?

@stonededge 5 месяцев назад

The driver board is custom designed & the display is a KD055HDFID001 which I ordered from Alibaba! I'm using all 4 MIPI lanes for it although you could probably get away with 2 lanes for 720p.

Hey, i love your work. keep it going. i am interested if the cm5 could possibly emulate the Switch. can you test it?

@stonededge 2 месяца назад

Hi, thank you! Yeah, I believe it can probably do some basic 2D games and maybe some light 3D ones. Unfortunately switch emulation requires a very new version of OpenGL (4.5 or greater) or Vulkan 1.2 graphics drivers, which aren't available except on Android right now. I am building a linux machine so I won't be able to test switch until we get Vulkan drivers.
