I have a B4860 based board, there is mini-pcie socket. It only uses one serdes lane from SERDES2.
I want to know if it is supported one lane for pcie controller 1. And how to change the dts to support the mini-pcie?
Thank you very much!
In the processor's RM it is written:
"PCI Express (PCIe) and SRIO• Downgrading is feasible-for example, if 4x is supported, then downgrading for 2x and 1x is possible. Downgrading is automatically controlled by the IP."
The x1 PCIe will be possible if the SerDes 2 Lane A is connected to the slot and appropriate SerDes 2 protocol is selected in the RCW.
