I am use PCIe to communicate between two Xaviers now, but I have some problem.
According to document 《NVIDIA Jetson AGX Xavier PCIe Endpoint Software for L4T》, I set the endpoint xavier as follows：
cd /sys/kernel/config/pci_ep/ mkdir functions/pci_epf_nv_test/func1 echo 0x10de > functions/pci_epf_nv_test/func1/vendorid echo 0x0001 > functions/pci_epf_nv_test/func1/deviceid ln -s functions/pci_epf_nv_test/func1 controllers/141a0000.pcie_ep/ echo 1 > controllers/141a0000.pcie_ep/start
But in my system, I have no 141a0000.pcie_ep folder in /sys/kernel/config/pci_ep/controllers.
I have configured the kernel code, the kernel log as follows:
tegra-pcie-dw-ep 141a0000.pcie_ep: EP BAR DMA addr = 0XFFF00000
another pcie， lspci as as follows:
0005:01:00.0 Memory controller: NVIDIA Corporation Device 1ad4 (rev a1)
can you help me?
