你好，
jetson Xavier NX + Jetpack4.6.1
EP:
安装下面的文档进行操作：Jetson AGX Xavier PCIe Endpoint Mode — Jetson Linux<br/>Developer Guide 34.1 documentation
能够获取<BAR0_RAM_phys>，写入值(0x12345678)
如下图：

ROOT：
在x86上能够看到ep端的设备,按文档中读取的值不正确，如下图：

这个问题怎么解决？谢谢！

On RP side, set below one. You have to modify the 0005:01:00.0 to match your device.

setpci -s 0005:01:00.0 COMMAND=0x02

Also, for rel-32, need to refer to this document.
