I refer the NVIDIA Jetson AGX Orin Series PCIe Endpoint Design Guidelines ,config the orin to root mode and endpoint mode ,but I find the shared RAM is 4k.I want to use the share RAM about 512M. How to config the endpoint mode? The system version being used is 35.1. Thank you!
We plan to use two orin. orinA should transfer image and other data to orinB by DMA.

Try to configure it in the driver code.
