CAN PCIE x8 configure as RC while PCIE x4 configure as EP?

We have such an application,XavierA’s PCIE x8 configure as RC while x4 configure as EP, XavierB’s PCIE x8 and x4 both configure as EP. Two xavier are connected via PCIE x8. Can it be achieved?

Please refer to the app note: https://developer.nvidia.com/embedded/dlc/jetson-agx-xavier-series-pcie-endpoint-design-guidelines-application-note

Endpoint is supported on C5 only.

You mean only C5 can configured as EP?

How to explain this?

You misunderstand the sentence. EP is supported on C5 only.

You misunderstand the sentence. EP is supported on C5 only.

What? That paragraph is quite hard to misunderstand! I was hoping to use one of the other controllers as an end-point as well so this comes as quite a surprise. That sentence has been in the documentation for quite some time.

Please take OEM DG as reference. The sentence in the paragraph will be corrected.
