RT117H Ethernet interface

[rubensjunior]

I have a demoboard of the i.MXRT117H as the bellow link.

However this demoboard have only wifi and I need realize a ethernet wired comunication. I read the datasheet (bellow link) but I hasn't find the pinmap for conect a ethernet circuit (RJ45 conector, PHY IC).

Can anybody help-me?

Hi @rubensjunior,

The RT117H does have capability for ethernet connections. However, as you can see on the SLN-TLHMI-IOT Hardware Design Files, the SLN-TLHMI-IOT does not have any ethernet routings or pads available to use for this module. Most of the ENET pins are routed to port GPIO_AD:

Which are already in use for the RGB and IR cameras:

Thank you @EdwinHz ! Can I Know a alternative for use the camera and Ethernet too? Our company needs this scenario.

Thank you!

Hi @rubensjunior ,

I have identified some pins for the ENET 1G Ethernet Controller. You can verify these in the Pin Configuration tool. These pins offer multiple functionalities, and I found the following features for the 1G Ethernet:

• RGMII/RMII/MII operation
• Support for IEEE1588
• Support for AVB

The required pins for Ethernet are mentioned in the Pin Configuration tool. Please match the Ethernet pins from the tool with the pin mapping table I am sharing here.

Note: I have not tested these pins; the pin mapping design is as per the MCU Expresso Config Tool.

I hope this will be helpful to you.

Additionally, @EdwinHz, could you please guide this suggestion?
