How am I supposed to install the HDMI Linux version on the eMMC once I have booted with the SDCard?
Thanks.

Hi Admin,

I get the below error when I restart the orange pi rk3399

I'm seeing this too. Googling pointed to a build.prop mismatch but I was not able to resolve. Any official word on fixing this? I'm using OrangePi-rk3399_Android_update_20180712.img.

Anyone have any idea about HDMI in with Audio? I'm trying to build an app to use the board as a projector, and the video stream is good to go, just the audio is the problem.

I was able to build a kernel with CONFIG_SND_SOC_ROCKCHIP_RT5651_TC358749 however that is clearly not enough, there seems to be a need to modify the DTS to support Audio in HDMI IN, anyone have any idea what these changes are? I'm rather stumped by this and a google search didnt yeild many results.


I'll also be happy to share my built kernel with anyone who wants to help me with this.

@gounthar: No, I built the kernel by cloning the OrangePi_Build repository from github on a PC. I only ended up flashing the kernel over the existing HDMI IN image.

Today I'm going to put this in the DTSI and DTS:

dtsi:
  1. rt5651-sound {
  2.                 compatible = "simple-audio-card";
  3.                 simple-audio-card,format = "i2s";
  4.                 simple-audio-card,name = "realtek,rt5651-codec";
  5.                 simple-audio-card,mclk-fs = <256>;
  6.                 simple-audio-card,widgets =
  7.                         "Microphone", "Mic Jack",
  8.                         "Headphone", "Headphone Jack";
  9.                 simple-audio-card,routing =
  10.                         "Mic Jack", "MICBIAS1",
  11.                         "IN1P", "Mic Jack",
  12.                         "Headphone Jack", "HPOL",
  13.                         "Headphone Jack", "HPOR";
  14.                 simple-audio-card,cpu {
  15.                         sound-dai = <&i2s0>;
  16.                 };
  17.                 simple-audio-card,codec {
  18.                         sound-dai = <&rt5651>;
  19.                 };
  20.         };
Copy the Code


dts:
  1. //5651 instead of only simple-audio-card
Copy the Code

  1. rt5651-sound {
  2.                 status = "disabled";
  3.         };

  4.         hdmiin-sound {
  5.                 compatible = "rockchip,rockchip-rt5651-tc358749x-sound";
  6.                 rockchip,cpu = <&i2s0>;
  7.                 rockchip,codec = <&rt5651 &rt5651 &tc358749x>;
  8.                 status = "okay";
  9.         };
Copy the Code
I lpicked these from the sapphire excavator board files.

Fingers crossed.
