Setting up

Hardware setup

Porting Mbed OS requires the following hardware:

  • A development PC. You can port targets, connectivity and storage on Windows, macOS or Linux. However, due to limitations in some development tools that Mbed OS uses, you need a Windows PC for DAPLink/FlashAlgo development.
  • An evaluation board with a target MCU, debug probe or an integrated interface chip.
  • A storage device (SD or external flash).
  • A micro SD card for the CI test shield.
  • A USB cable to connect the evaluation board to your development PC.

Note: The new target needs a unique board ID. To get one, please contact your technical account manager or email our support team.

If there is no interface MCU on the board you may also need:

  • A debug probe, such as SWDAP-LPC11U35. You will then need a USB cable (in addition to the USB cable listed above).
  • An FTDI TTL232R-3V3 USB cable, for the Tx and Rx pins of debug probes that do not have a serial connection.

The following items might help you test SPI, I2C and pins:

Check the user guide of the evaluation board to see if anything needs to be done prior to using a debug probe and running Mbed OS programs.

Software setup

Please install the following:

  • Python.

  • Git.

  • Mbed CLI.

  • Choose an IDE and debugger. The three commonly used IDEs are Eclipse, IAR Embedded Workbench and Keil MDK.

    Limitations:

    • Eclipse is license free, whereas both IAR and Keil IDE require licenses.
    • Your target may not be supported in certain IDEs.
    • If your interface firmware does not support mass storage device, you won't be able to do automated testing. If your target has another method of flashing, such as self-programming or through a debugger, use the manual testing path.
  • (Optional) FTDI serial driver.

The tools documentation contains the exact third party tool versions supported in a specific Mbed OS release.
