NXP i.MX RT1050 (MIMXRT1050-EVKB) Evaluation Kit

This topic provides board-specific information about for NXP's i.MX RT1050. Assuming that you have set up the development environment as per the intructions in getting started.

Board features

  • MIMXRT1052DVL6B MCU featuring 600MHz ARM® Cortex®-M7 core, 512KB RAM
  • 4.3” 480x272 RGB Touch Display
  • 256-Mbit SDRAM memory
  • 512-Mbit Hyper Flash
  • 64-Mbit QSPI Flash
  • Socket for SD card

Prebuilt demos and examples

The package for NXP i.MX RT1050 Evaluation Kit board comes with the following prebuilt demos and examples:

You can find these from demo_images directory.

See Flashing Instructions for NXP boards section on how to flash the device.

Note: Flashing may not work for small applications. See Known Issues section for more information.

Known issues

  • The interrupted program does not resume its execution while debugging. It must be restarted using the mon reset halt command.
  • CMake flash targets may not work properly for small application binaries. Use gdb to workaround this problem.

Reading debug messages

By default, the output of printf calls are redirected to a virtual serial port, which is exposed on the host machine via USB.

Debugging

For convenience, you can set an environment variable that points to the Redlink tool, which is part of the MCUXpresso IDE.

Linux host:

export REDLINK=$MCUXpressoIDE_PATH/ide/binaries/crt_emu_cm_redlink

Windows host:

set REDLINK=%MCUXpressoIDE_PATH%\ide\binaries\crt_emu_cm_redlink

Where, MCUXpressoIDE_PATH is an environment variable pointing to the MCUXpresso IDE installation directory.

  • Open a terminal window and run the following command:

    Linux host:

    $REDLINK --server :50032 --mi -2 -vc --connect-reset core -p MIMXRT1052xxxxB --ConnectScript RT1050_connect.scp --flash-driver= -x $Qul_DIR/platform/boards/nxp/mimxrt1050-evk-common/cmake

    Windows host:

    %REDLINK% --server :50032 --mi -2 -vc --connect-reset core -p MIMXRT1052xxxxB --ConnectScript RT1050_connect.scp --flash-driver= -x %Qul_DIR%\platform\boards\nxp\mimxrt1050-evk-common\cmake

    GDB Server is now listening for TCP connections on port, 50032.

    Note: To change TCP port used by redlink_server, change --server :50032 to different value.

  • Run arm-none-eabi-gdb in a separate console

    Linux host:

    $ARMGCC_DIR/bin/arm-none-eabi-gdb.exe <PATH_TO>/your_app.elf

    Windows host:

    %ARMGCC_DIR%\bin\arm-none-eabi-gdb.exe <PATH_TO>\your_app.elf
  • Connect to the target via the gdbserver in the arm-none-eabi-gdb console using
    (gdb) target remote :50032
  • Alternatively, flash the target device from the arm-none-eabi-gdb console using the following command:
    (gdb) load
