This is the documentation for the latest (main) development branch of mcuxpresso sdk. If you are looking for the documentation of previous releases, use the drop-down menu on the left and select the desired version.

Run an example application

To download and run the application, perform these steps:

Reference the table in Default debug interfaces to determine the debug interface that comes loaded on your specific hardware platform.
Connect the development platform to your PC via USB cable.
Open the terminal application on the PC, such as PuTTY or TeraTerm, and connect to the debug serial port number (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_BAUDRATE variable in the board.h file)
2. No parity
3. 8 data bits
4. 1 stop bit |

|

To debug the application, click load (or press the F8 key). Then, click the Start/Stop Debug Session button, highlighted in red in Figure 2. If using J-Link as the debugger, click Project option >Debug >Settings >Debug >Port, and select SW.

Note: When debugging with jlink, it expects one jlinkscript file named JLinkSettings.JLinkScript in the folder where the uVision project files are located. For details, see SEGGER Wiki. For the contents in this JlinkSettings.JLinkScript, use contents in evkmimxrt1020_sdram_init.jlinkscript.

Note: Make sure that the board is set to FlexSPI flash boot mode (ISP2: ISP1: ISP0 = ON, OFF, ON) before using Keil debug.

Run the code by clicking Run to start the application, as shown in Figure 3.

The `hello_world` application is now running and a banner is displayed on the terminal, as shown in [Figure 4](run_an_example_application_001.md#S127DD02). If this is not true, check your terminal settings and connections.
