The pcie has automatically support lane reversal on xavier past post.
Our AGX Orin carrier board have one M.2Key M pcie x4 [lane3~0] with B+M PCIEx2 SSD [lane3-2] on pcie lane reversal mode. The SSD should work properly.
If we want to design the new one AGX Orin carrier board, but its M.2Key M pcie x4 [lane0~3] is not use pcie lane reversal. And use B+M PCIEx2 SSD [lane0-1].
Could we use the same Orin module directly support two carrier board?
If provide a GPIO to identify carrier board, could the lane reversal be control?
