5.5. Multiplexer
There are 4 multiplexers on board to support various configurations possibilities. These multiplexers are configured in
the BSP. Below you will find more information on the different multiplexers on the SMARC module:

SATA/PCIe
DSI1 / eDP DP
DSI1 / LVDS0 Channel1
(Standard SMARC 2.0 module pinout)
DS1 / (SPI3 and CAN3)
(Custom SMARC module pinout)
HDMI and DisplayPort / HDMI RX
5.6. SMARC Connector
The SMARC connector has different pins on both sides:
Top side: 74 pins are on the left side, 82 pins on the right side
Bottom side: 75 pins are on the left side, 83 pins on the right side

Description
Allow to choose between an additional PCIe port or a SATA port. Do note that there is only
two roots port for PCIe device.
Allow to choose between the eDP/DP bridge chip or DSI0 from the SoC on the SMARC
connector. DSI0 is going through a second mux since DSI0 is shared with LVDS Channel1.
Note: DSI0 from SoC is connected to DSI1 on SMARC connector.
Allow to choose between the DSI0 from the SoC or the LVDS0 Channel1. Do note that the
multiplexer DS1 / eDP DP should be set to DSI for the DSI option to work.
Allow to choose between the DSI0 from the SoC or SPI3 and CAN3. Do note that the
multiplexer DS1 / eDP DP should be set to DSI for the DSI option to work.
Allow to choose between the HDMI/DP TX from the SoC or HDMI RX from the SoC
