你好，
orin nx (jetpack6.1)设置成EP,
RP是x86(Ubuntu22.04);
ep端已按照文档[ PCIe Endpoint Mode — NVIDIA Jetson Linux Developer Guide 1 documentation]设置，RP也重启，并能查看到ep设备，但是输入：cat edmalib_test，会显示没有权限，并没有出现文档中显示的内容，dmesg，报出如下错误：[ 666.671660] pcie_dma_epf tegra_pcie_dma_epf.0: RP DMA address is null，RP端也找不到/sys/kernel/debug/0004:01:00.0_pcie_dma_test/这个目录。请问该怎么做？ 谢谢
Sorry for the late response.
Is this still an issue to support? Any result can be shared?
感谢您的回复，问题还没有解决，主机端虽然能够看到设备但是没有0004:01:00.0_pcie_dma_test这个文件夹。
我們的driver沒有支援RP x86的情況. 只有測過Orin to Orin.
PCIe Endpoint Mode — NVIDIA Jetson Linux Developer Guide 1 documentation ，文档中提到是任何x86的Linux主机
對. 所以你的host PC可以讀到Jetson EP in lspci. 但後續的driver for tegra_pcie_dma_epf是沒有支援的. 請自行針對x86 host撰寫driver.
Even we have similar issue, please let us know in case if you get custom drivers for x86 Root Complex.
Thanks.
