My development requirement is to connect two development boards using a physical cable. One development board will transmit commands to the NX development board through a physical cable (currently using PCIE) to enable NX to perform machine learning work. But I found it difficult to find tutorials and code about PCIE communication. May I ask how I can find a tutorial or if there are other better alternatives to achieve this task.
Thank you, I have read and experimented with this document a few days ago, but I did not find the Jetson Linux kernel source package in NX. Namely: nvidia/drivers/pci/endpoint/functions/pci-epf-nv-test.c， There is no Nvidia folder in the kernel folder.
The kernel source code is in separate package downloaded from the website.
