The goal of this project is to provide a common bootloader for multiple (all?) Pinetime projects. It allows to upgrade the current bootloader and even replace the current application by another one that supports the same bootloader.
|
||||
|
||||
As we wanted this bootloader to be as universal as possible, we decided that it should **not** integrate a BLE stack and provide OTA capabilities.

As we wanted this bootloader to be as universal as possible, we decided that it should **not** integrate a BLE stack and provide OTA capabilities.
|
||||
|
||||
Integrating a BLE stack for the OTA functionality would have used to much memory space and/or forced all the firmware developers to use the same BLE stack as the bootloader.

- **The primary slot** : it contains the current firmware, the one that will be executed by MCUBoot

- **The secondary slot** : it is used to store the upgraded version of the firmware, when available.

This chapter describes degraded cases that are handled by our bootloader and those that are not supported.

New firmware does not run at all (bad file) (1) | [NOK] MCU executes unknown instructions and will most likely end up in an infinite loop or freeze in an error handler. The bootloader does not run, it can do nothing, the MCU is stucked until next reset | [OK] The bootloader starts the watchdog just before running the new firmware. This way, the watchdog will reset the MCU after ~7s because the firmware does not refresh it. Bootloader reverts to the previous version of the firmware during the reset.
