Run an example application

To download and run the application, perform these steps:

1. This board supports the CMSIS-DAP/mbed/DAPLink debug probe by default. Visit MBED and follow the instructions to install the Windows® operating system serial driver. If running on Linux OS, this step is not required.

2. Connect the development platform to your PC via USB cable. Connect the USB cable to J11 and make sure SW1[1:4] is 0010b.

3. Open the terminal application on the PC, such as PuTTY or TeraTerm, and connect to the debug COM port (to determine the COM port number, see How to determine COM port). Configure the terminal with these settings:

   1. 115200 or 9600 baud rate, depending on your board (reference BOARD_DEBUG_UART_BAUDRATEvariable in the board.hfile)

   2. No parity

   3. 8 data bits

   4. 1 stop bit

4. In IAR, click the Download and Debug button to download the application to the target.

   

   • When using CMSIS-DAP to debug cm4 project on IAR, an extra option need to be specified in debugger settings. Check and fill in –macro_param enable_core=1 in Debugger -> Extra Options -> Command line options, as shown in Figure 3.

     

   • If debug with JLINK as probe, jlinkscript file is needed.

     • When downloading the cm7 project, check Use command line options, as shown in Figure 4.

       

     • When downloading the cm4 project, uncheck Use flash loaders, as shown in Figure 5, and change the contents of command line options as below:

       • Target with SDRAM

         _ --jlink_script_file=$PROJ_DIR$/../evkbmimxrt1170_connect_cm4_cm4side_sdram.jlinkscript
         

       • Other target

         --jlink_script_file=$PROJ_DIR$/../evkbmimxrt1170_connect_cm4_cm4side.jlinkscript
         

     

5. The application is then downloaded to the target and automatically runs to the main() function.

   

6. Run the code by clicking the Go button to start the application.

   

7. The hello_world application is now running and a banner is displayed on the terminal. If this is not true, check your terminal settings and connections.

   

Note: There are some limitations on MCUXpresso IDE debugging. For details, see Section 8.6 IAR debug limitation in MCUXpresso SDK Release Notes for MIMXRT1170-EVKB (document MCUXSDKMIMXRT117XBRN).
