Example for non-default UART on Nuvoton's Mbed CE enabled boards

This is an example to demo non-default UART on Nuvoton's Mbed CE enabled boards.

Check out Mbed CE for details on Mbed OS community edition.

Support development tools

Use cmake-based build system. Check out hello world example for getting started.

⚠️ Warning

Legacy development tools below are not supported anymore.

• Arm's Mbed Studio
• Arm's Mbed CLI 2
• Arm's Mbed CLI 1

For VS Code development or OpenOCD as upload method, install below additionally:

• NuEclipse: Nuvoton's fork of Eclipse
• Nuvoton forked OpenOCD: Shipped with NuEclipse installation package above. Checking openocd version openocd --version, it should fix to 0.10.022.

Developer guide

In the following, we take NuMaker-IoT-M467 board as an example for Mbed CE support.

Hardware requirements

• NuMaker-IoT-M467 board
• Host OS: Windows or others
• Nu-Bridge: Connect UART RX/TX to target board's UNO D1/D0

Build the example

1. Clone the example and navigate into it

   $ git clone https://github.com/mbed-nuvoton/NuMaker-mbed-ce-uart-example
   $ cd NuMaker-mbed-ce-uart-example
   $ git checkout -f master
   

2. Deploy necessary libraries

   $ git submodule update --init
   

   Or for fast install:

   $ git submodule update --init --filter=blob:none
   

3. Compile with cmake/ninja

   $ mkdir build; cd build
   $ cmake .. -GNinja -DCMAKE_BUILD_TYPE=Develop -DMBED_TARGET=NUMAKER_IOT_M467
   $ ninja
   $ cd ..
   

Flash the image

Flash by drag-n-drop built image NuMaker-mbed-ce-uart-example.bin or NuMaker-mbed-ce-uart-example.hex onto NuMaker-IoT-M467 board

Verify the result

On host terminal (115200/8-N-1), you should see below via Nu-Bridge:

Hello NuMaker 1
Hello NuMaker 2
Hello NuMaker 3
