i.MX8QXP DisplayPort over USB-C

nolan_zinn — Wed, 29 Apr 2020 15:56:30 GMT

Hi all! Does anyone know if it is possible to run DisplayPort over USB-C? I checked out https://www.displayport.org/displayport-over-usb-c/ and it looks like you need to be able to run USB 3.1 on the USB-C port to support DP. I'm not sure if the i.MX8QXP even supports USB 3.1 on Type-C... If so, how would we build that functionality into Yocto?

Regards,

Nolan Z

Hello Nolan Z,

According to the current datasheet for the i.MX8QuadXPlus, it supports USB 3.0.

https://www.nxp.com/docs/en/data-sheet/IMX8QXPAEC.pdf

Setting up the USB version limitation, I haven’t seen this specific functionality available as part of the Yocto Project for the i.MX processors.

Some third parties like WindRiver may have some approximate implementations like the following, but I haven’t seen any ported to i.MX Processors (perhaps due to the USB 3.1 limitation)

My apologies for the inconvenience!

Regards,
