    how to enable PCIe #1 in software on the Atom 3825 Processor

      Hi

       

      Two mPCIe interfaces are added to the Custom Minnowbooard max board to connect two WiFi modules. One mPCIe interface is connected to the PCIE #1 and another is connected to the PCIE #3 on ATOM 3825 Processor. I could able to see one PCIe bus (PCIE #3) in the OS, using lspci and I am unable to find PCIE #1 interface in the OS. I enabled all the PCIe slots in the BIOS and also included all the necessary kernel modules in the kernel config.  

       

      Please tell me if anyone knows how to bring up the PCIe #1 interface, any suggestions/ inputs are highly appreciated.      

       

      Details:

       

           Processor: INTEL ATOM

           OS: OpenWrt/ Buildroot

       

           lspci result:
