2. 3 2 Other Development Tools Process of creating new projects typically heavily depends on the development environment being used Describing this process for tools other than Freescale CodeWarrior is out of scope of this document For more information refer to MQX support documentation provided by the tool vendor A general recommendation for starting a new MQX project in any IDE environment is to clone one of the existing example applications save it under a custom name and modify it to meet your specific needs In this case please be aware that there may be relative paths to support files referred in the project This may apply to include search paths linker command files debugger configuration files etc Make sure that you update the relative paths in the new clone of the project Freescale MQX Getting Started Freescale Semiconductor 9 4 MQX Standard Input and Output Channel Setting 4 1 Default IO Channel One of the I O communication devices installed by MQX BSP may be used as the standard IO channel e g Serial line IO Debug telnet USB CDC The default console setting for each supported development board is specified in the 7 Board specific Information Related to MQX chapter The Freescale Tower evaluation kits offer several ways to connect the lO console The most common options are listed below e Serial lO channel routed via TWR SER or TWR SER2 boards using RS232 connector This port can be connected directly to t

9. Process After any change to the compile time user configuration file or MQX kernel source files the MQX libraries need to be re built The build process is similar with all core components e The output directory is lt install dir gt lib lt board gt lt ide gt lt target gt lt component gt where lt ide gt is a name of build tool For example when CodeWarrior 10 tool is used to build MQX PSP and BSP libraries for TWR K60D100M board in debug targets the libraries are built into the lib twrk60d100m cw10 debug psp and lib twrk60d100m cw10 debug bsp directories Note In the MQX 4 0 the libraries output paths were changed The target names are now part of library output path while the name of the library file is the same for all targets The Debug versions of the libraries are no longer created with the d suffix which makes it easier to create custom build targets and change different versions of libraries easily in the application projects e All public header files needed by application are automatically copied from internal include folders to the same output directory as the library itself e During PSP or BSP build process also the user_config h file and other header files from the config lt board gt and config common directories are copied into the lib lt board gt lt compiler gt lt target gt output directory Freescale MQX Getting Started 4 Freescale Semiconductor It is strongly recommended to recompile all MQ
