I have a custom AM5718 design with a 800x480 display attached the DPI interface. I am using the Linux kernel 5.10.168 kernel from the ti-processor-sdk-linux-am57xx-hs-evm-08_02_01_00 SDK. My device tree node is shown below. I have DPI support , support for simple panels, and simple framebuffer support enabled. With that being said, when the board boots, the display is not being recognized and /dev/fb0 is not being created. Any thoughts on what I am missing?
Thanks,
Bill Kanczes
