Xavier NX using PCIE 2+2 mode?

The Xavier NX has x1 PCIe lane and x4 PCIe lanes exposed to the SOM slot. Can the x4 PCIe be run as 2+2 so that 2 devices could connect to the previous “x4 PCIe” slot while preserving the x1 PCIe slot?

Is there documentation which shows how to set this up in the Kernel DTB?

Thank you,

andy

Sorry that it is not supported. Only the same mapping as devkit is allowed.
