How to control HDMI drive strength? #481

Open ShaoHao-Chen opened 3 years ago

ShaoHao-Chen commented 3 years ago

I am facing issues with HDMI port during EMI test. In the NXP Community, it mention the HDMI firmware can be changed.

My Question

  1. The NXP only support the YOCTO project, so something is different. I can't find the file "firmware-imx-8.12.bin", but I see the file /usr/share/imx-firmware/imx8m/signed_hdmi_imx8m.bin. Does these two file mean the same thing?
  2. Where can find source code to build and change the firmware setting?
  3. Does USB drive strength can be changed like HDMI?

Could I change the bin file setting to rebuild the whole kernel?
