Firmware for Pinetime smartwatch written in C++ and based on FreeRTOS

The only change between the 2 linker scripts is the ORIGIN address of the flash memory allocated to InfiniTime. The MCUBoot one starts at 0x8000, which is the address that will be loaded by MCUBoot after the boot process. This linker script allow to run the application without MCUBoot by setting the origin address to 0x00. The APP_SIZE is the same for both linker scripts, but it could be set to a higher value in this one for development purposes. |

Credits
I’m not working alone on this project. First, many people create PR for this projects. Then, there is the whole #pinetime community : a lot of people all around the world who are hacking, searching, experimenting and programming the Pinetime. We exchange our ideas, experiments and code in the chat rooms and forums.
Here are some people I would like to highlight:
- Atc1441 : He works on an Arduino based firmware for the Pinetime and many other smartwatches based on similar hardware. He was of great help when I was implementing support for the BMA421 motion sensor and I²C driver.
- Koen : He’s working on a firmware based on RiotOS. He integrated similar libs as me : NimBLE, LittleVGL,… His help was invaluable too!
- Lup Yuen Lee : He is everywhere: he works on a Rust firmware, builds a MCUBoot based bootloader for the Pinetime, designs a Flutter based companion app for smartphones and writes a lot of articles about the Pinetime!
