HDMI RX on IMX8QM

Dear All,

I'm interested in the HDMI RX interface available uniquely on iMX8QM. However, there are not many discussions on that interface. I browsed this Community forum and found below tickets and sharing :

https://community.nxp.com/t5/i-MX-Processors/HDMI-RX-or-HDMI-IN-on-imx8qm-mek-with-Android-9-Auto/m-p/987568

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-mx8qm-HDMI-RX/ta-p/1111058

I might missing some. Therefore, I would like to know if it is available and stable in recent BSPs (from 5.4.70-2.3.x onward), please ?

Thanks very much in advance and look forward to hearing from you.

Best regards,

Khang

Hi Khang

unfortunately HDMI RX is not listed among supported functionalities in i.MX Linux Release Notes

also footnote 3 Table 8. Operating ranges i.MX 8QuadMax Automotive and Infotainment Applications Processors states: "HDMI-RX is not currently supported.."

Best regards

Hi @igorpadykov ,

Thanks for the confirmation. I would like to know if there would be any plan to support the interface in future as it is part of the SoC's HW, please ?

Regards,
Khang

software and production plans can be obtained only through local marketing channels.

I can see from the recent articles that the hdmi rx is working. I was hoping to understand with the iMX8 SOC if:

1.4k, 30fps AND 10 bit 422 is supported

2. if the iMX8 supports USB 3 OTG device mode

Hoping the SOC could be a solution to capture frame data through the USB to a host device.

Thanks
