Onboard Interfaces and Devices
10.1
UART/RS-232 Debug Port
The conga-QMX6 is equipped with a six-pin RS232 connector onboard the conga-QMX6. This RS-232 debug port is connected to the Freescale
®
i.MX6 UART1 and UART2 pins via the MAXIM-3232 transceiver. The transceiver is guaranteed to run at data rates of 250kbps in normal
operating mode, while maintaining RS-232 output levels.
Refer to section 5.2 for more information about the UART interface.

Note
The RS232 adapter cable (PN: 48000023) for the onboard UART interface is included in the congatec Qseven Evaluation kit. You can also
order this cable separately from congatec AG. For more information, contact your congatec sales representative.

MIPI/CMOS Camera
The Freescale® i.MX6 Image Processing Unit (IPU) provides connectivity to cameras via the MIPI/CSI-2 transmitter and maintains image
manipulation and processing with adequate synchronization and control. The Camera Serial Interface (CSI) controls the camera port and
provides interface to an image sensor or a related device. The role of the camera ports is to receive input from video sources and to provide
support for time-sensitive signals to the camera. Non-time-sensitive controls such as configuration, reset are performed by the ARM platform
through I2C interface or GPIO signals
Note
The conga-QMX6 BSPs do not currently support the camera interface.
