| Porting Mynewt to a new MCU |
| =========================== |
| |
| Porting Mynewt to a new MCU is not a difficult task if the core CPU |
| architectures is already supported. |
| |
| The depth of work depends on the amount of HAL (Hardware Abstraction |
| Layer) support you need and provide in your port. |
| |
| To get started: |
| |
| - Create a ``hw/mcu/mymcu`` directory where ``mymcu`` is the MCU you |
| are porting to. Replace the name ``mymcu`` with a description of the |
| MCU you are using. |
| - Create a ``hw/mcu/mymcu/variant`` directory where the variant is the |
| specific variant of the part you are usuing. Many MCU parts have |
| variants with different capabilities (RAM, FLASH etc) or different |
| pinouts. Replace ``variant`` with a description of the variant of the |
| part you are using. |
| - Create a ``hw/mcu/mymcu/variant/pkg.yml`` file. Copy from another mcu |
| and fill out the relevant information |
| - Create |
| ``hw/mcu/mymcu/variant/include``, ``hw/mcu/mymcu/variant/include/mcu``, |
| and ``hw/mcu/mymcu/variant/src`` directories to contain the code for |
| your mcu. |
| |
| At this point there are two main tasks to complete. |
| |
| - Implement any OS-specific code required by the OS |
| - Implement the HAL functionality that you are looking for |
| |

| to new MCU. |
