I'm having trouble getting the PCIE up on the i.MAX6 Quad Sabre Lite Development board (https://boundarydevices.com/product/sabre-lite-imx6-sbc/ ) and interfacing with TW6865 Intersil video chip and I couldn't find the sufficient details on how to connect REFCLK- and REFCLK+ of TW6865 with PCIE port of the i.MAX6Q Sabre Lite as it just have following pin connections.
- Can you guide me to interface TW6865 with PCIE of Sabre Lite ? (Presently I'm working 3.14.52 kernel based system)
- When I check the schematic of Sabre lite board I could find there is no pin connection for CLK1_N and CLK1_P (C7 & D7 pins of processor) for PCIe clock. So it seems that we need to generate reference clock externally as it has done in PCIe Daughter board ( https://boundarydevices.com/product/nit6x_pcie/ ). If I need to build external clock what is the frequency should I generate for PCIE ? (Because I'm not using PCIE daughter board) Can you trll me the frequency of the on board oscillator of PCIE Daughter board ?
- If I'm using 3.14.52 kernel what are the configurations should I follow ?
