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: If you intend to release a new target to the Mbed community, it needs a unique four-digit hexadecimal identifier called a Platform 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:
- A CI test shield v2.0.0. For details, refer to https://github.com/ARMmbed/ci-test-shield.
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:
-
Git.
-
Choose an IDE and debugger. The two commonly used IDEs are Eclipse and Keil MDK.
Limitations:
- Eclipse is license free, whereas 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.
