As previously stated, SBC-C57 offers in addition to
LVDS interface, as a factory configuration, a dedicated
embedded Display Port interface. Such an interface is
derived from the processor's MIPI-DSI #0 Interface.
When this interface is present and connected, LVDS interface can work only in single channel
mode from -DSI #1 Interface
For the connection of this kind of displays, on-board there is a VESA
embedded Display Port interface, type STARCONN p/n 300E40-0110RA-G3 or equivalent
(microcoaxial cable connector, 0.5mm pitch, 40 positions).
voltages (VCC_LCD and VCC_BLT) and control signals (BLT_EN and BLT_CTRL) which are
shared with the LVDS connector and will affect the backlight behaviour of the LVDS panel if
present (see par.3.3.4).
Output values of VCC_LCD and VCC_BLT can be configured using jumpers as indicated in
par. 3.3.5.
Here following the signals involved in eDP management:
eDP_ML0+/eDP_ML0-: embedded DP differential data pair #0.
eDP_ML3+/eDP_ML1-: embedded DP differential data pair #1.
eDP_ML3+/eDP_ML2-: embedded DP differential data pair #2.
eDP_ML3+/eDP_ML3-: embedded DP differential data pair #3.
eDP_AUX+/eDP_AUX-: embedded DP auxiliary channel differential data pair.
BKLT_EN: LCD_PWR electrical level Output with a 10kΩ pull-up resistor, Backlight Enable
signal. It can be used to turn On/Off the backlight's lamps of connected displays.
BKLT_PWM: this signal can be used to adjust the backlight brightness in displays supporting
Pulse Width Modulated (PWM) regulations (LCD_PWR electrical level).
