Build an example application

Do the following steps to build the hello_world example application.

1. Open the desired demo application workspace. Most example application workspace files can be located using the following path:

   <install_dir>/boards/<board_name>/<example_type>/<application_name>/iar
   

   Using the IMXRT1050-EVKB hardware platform as an example, the hello_world workspace is located in:

   ><install_dir>/boards/evkbimxrt1050/demo_apps/hello_world/iar/hello_world.eww
   

   Other example applications may have additional folders in their path.

2. Select the desired build target from the drop-down menu.

   There are twelve project configurations (build targets) supported for most MCUXpresso SDK projects:

   • Debug – Compiler optimization is set to low, and debug information is generated for the executable. The linker file is RAM linker, where text and data section is put in internal TCM.

   • Release – Compiler optimization is set to high, and debug information is not generated. The linker file is RAM linker, where text and data section is put in internal TCM.

   • ram_0x1400_debug – Project configuration is same as the debug target. The linker file is RAM_0x1400 linker, where text is put in ITCM with offset 0x1400 and data put in DTCM.

   • ram_0x1400_release – Project configuration is same as the release target. The linker file is RAM_0x1400 linker, where text is put in ITCM with offset 0x1400 and data put in DTCM.

   • sdram_debug – Project configuration is same as the debug target. The linker file is SDRAM linker, where text is put in internal TCM and data put in SDRAM.

   • sdram_release – Project configuration is same as the release target. The linker file is SDRAM linker, where text is put in internal TCM and data put in SDRAM.

   • sdram_txt_debug – Project configuration is same as the debug target. The linker file is SDRAM_txt linker, where text is put in SDRAM and data put in OCRAM.

   • sdram_txt_release – Project configuration is same as the release target. The linker file is SDRAM_txt linker, where text is put in SDRAM and data put in OCRAM.

   • flexspi_nor_debug – Project configuration is same as the debug target. The linker file is flexspi_nor linker, where text is put in flash and data put in TCM.

   • flexspi_nor_release – Project configuration is same as the release target. The linker file is flexspi_nor linker, where text is put in flash and data put in TCM.

   • flexspi_nor_sdram_release - Project configuration is same as the release target. The linker file is flexspi_nor_sdram linker, where text is put in flash and data put in SDRAM.

   • flexspi_nor_sdram_debug – Project configuration is same as the debug target. The linker file is flexspi_nor_sdram linker, where text is put in flash and data put in SDRAM. For some examples need large data memory, only sdram_debug and sdram_release targets are supported.

   For this example, select hello_world – debug.

   

3. To build the demo application, click Make, highlighted in red in Figure 2.

   

4. The build completes without errors.
