This example is based on mbed-ce-custom-targets and demonstrate how to run custom targets under MbedCE. For example BluePill STM32F103

This guide assumes you are familiar with the MbedCE build system, if not, please visit https://github.com/mbed-ce/mbed-os/wiki

1. Open OS Command line and navigate to your workspace, for exampe C:\MbedCE_projects\
2. Into Command line type

• git clone --no-recurse-submodules https://github.com/mbed-ce-libraries-examples/Custom-target-example-Extended.git HerePlaceMyProjectName
• cd HerePlaceMyProjectName && git submodule update --init -- mbed-os custom_targets
• if you want to move MbedOS to the latest tracked commit without fetching nested submodules inside mbed-os, use git submodule update --remote -- mbed-os
• nested submodules inside mbed-os are intentionally not downloaded here because the build system handles them automatically

3. On the last line of cmake-variants.yaml file set your upload method. Default is NONE = it generates just .bin file. Optimal for external loaders like DFU method and so on (I personaly prefer STM32CUBE).
4. Build the project
