IMX8QM DP++ (DisplayPort Dual-Mode)

Hi,

We've a custom (imx8qm) board with an mDP (mini DisplayPort) connector, and I'd like to connect an external HDMI screen using a passive mDP-HDMI adapter. My understanding is that this should be possible if DP++ (DisplayPort Dual-Mode) is supported.

I have a few questions regarding DP++ support on the i.MX8QM:

i.MX8QM DP++ Support: Does the i.MX8QM processor itself support DP++?
Cadence Firmware DP++ Support: Does the Cadence firmware for the i.MX8QM's DisplayPort controller support DP++?
Device Tree Configuration: Are there any necessary device tree (dtb) configurations required to enable and utilize DP++ functionality? If so, could you please provide details on the specific settings?

Thank you for your assistance.

Hello,

Unfortunately DisplayPort Dual-Mode is not supported in i.MX8QM, you need to look into another adapter.

I apologize the inconvenience that this may affect your design.

Best regards.
