3.3 Preparing for Downloading and Debugging
The target and development workstation must be properly configured and initialized before OS
images can be downloaded and executed. This section discusses the steps required to prepare the
target and development workstation so that the Platform Builder can be used to download and
debug images on the target.
Serial debug messages are used by the boot loader and OS images to report status and error
information. Additionally, the boot loader uses serial input to allow for user interaction. This
section describes the configuration of the desktop workstation and Freescale BSP to support serial
debug messages.
1) Desktop Workstation Serial Debug Port
Any terminal emulation application can be used to display messages sent from the serial port of the
target. Configure the terminal application with the following communications parameters:
 Bits per second—115200
 Data bits—8
 Parity—None
 Stop bits—1
 Flow control—None
2) Target Serial Debug Port
Connect a Cross-Over serial cable between CN9 of RSC-IMX51 and RS232 interface of the
development workstation.
