Note
conga-TR4 supports just one display output in BIOS setup menu and during boot-up phase. The priority of the displays is LVDS, DD1, DDI3,
DDI2. This means that there is no graphic output in BIOS setup menu on DDI1, DDI2 and DDI3 when the LVDS display interface is enabled.
5.1.9
Optional eDP
The conga-TR4 offers signals for LVDS by default. Optionally, the conga-TR4 can offer signals for eDP instead.
The eDP interface supports:
•
VESA eDP Standard version 1.4
•
Resolution up to 3840x2160 @60 Hz

GPIO
The conga-TR4 offers general purpose inputs and outputs for custom system designs and can be controlled by the congatec Board Controller
(cBC).
5.1.11
UART
The conga-TR4 offers signals for two UART interfaces routed from the SoC by default. Optionally, the signals can be routed from the congatec
Board Controller (cBC) instead.
Two TTL compatible two wire ports are available on Type 6 COM Express modules. These pins are designated SER0_TX, SER0_RX, SER1_TX
and SER1_RX. Data out of the module is on the _TX pins. Hardware handshaking and hardware flow control are not supported. The module
asynchronous serial ports are intended for general purpose use and for use with debugging software that makes use of the “console redirect”
features available in many operating systems.
The UART controllers integrated in the cBC support up to 1MBit/s and can operate in low-speed, full-speed and high-speed modes. The UART
interfaces are routed to the AB connector and require the congatec driver to function.
Note
The UART interfaces currently do not support legacy COM port emulation.
