We successfully implemented the B-LCDAD-HDMI on our platform. The solution for us was using the attached device tree and applying the following patch:https://patchwork.kernel.org/project/dri-devel/patch/20190627151740.2277-1-matt.redfearn@thinci.com/...

Hello Olivier,Yes, the root cause of the connectivity issue was the missing power connection to the RJ45 magnetics transformer. We have tested and confirmed the PHY is fully functional. Best regards,Paul

How to troubleshoot remoteproc on STM32MP157C.

Can someone please help. We are trying to implement a KSZ8041FTL Ethernet PHY using an STM32MP157C. We are not able to connect to the device via MDIO. The device does not respond.

Is there an example device tree and possibly connection diagram demonstrating how to enable the B-LCDAD-HDMI1 on an STM32MP1 based platform using DSI.
