### Stack
|

The stack will be used for everything except tasks, which have their own stack allocated by FreeRTOS. The stack is 8192B and is allocated in the [linker script](https://github.com/JF002/InfiniTime/blob/develop/nrf_common.ld#L148).

An easy way to monitor its usage is by filling the section with a known pattern at boot time, then use the firmware and dump the memory. You can then check the maximum stack usage by checking the address from the beginning of the stack that were overwritten.

You can comment the content of `m_iconMap` in the [Navigation](https://github.com/JF002/InfiniTime/blob/develop/src/displayapp/screens/Navigation.h#L148) application to free some memory.

Basically, a **firmware** is just a software running on the embedded hardware of a device, the PineTime in this case.

**InfiniTime** is based on 3 distinct **firmwares**:

|
||||
- **[The bootloader](https://github.com/JF002/pinetime-mcuboot-bootloader)** is responsible for safely applying **updates** of the *application firmware*, reverting them in case of issues and load the recovery firmware when requested.
|
||||
- **The recovery firmware** is a specific *application firmware* than can be loaded by the bootloader on user request. This firmware can be useful in case of serious issue, when the main application firmware cannot perform an OTA update correctly. Currently, this recovery firmware is based on [InfiniTime 0.14.1](https://github.com/JF002/InfiniTime/releases/tag/0.14.1).

|

|

**OTA** and **DFU** refer to the update of the firmware over BLE (**B**luetooth **L**ow **E**nergy). **OTA** means **O**ver **T**he **A**ir, this is a functionality that allows the user to update the firmware how their device using a wireless communication like BLE. When we talk about **DFU** (**D**igital **F**irmware **U**pdate), we refer to the file format and protocol used to send the update of the firmware to the watch over-the-air. InfiniTime implement the (legacy) DFU protocol from Nordic Semiconductor (NRF).

## How to check the version of InfiniTime and the bootloader?
|
||||
|
||||
Since September 2020, all PineTimes (devkits or sealed) are flashed using the **[first iteration of the bootloader](https://github.com/lupyuen/pinetime-rust-mynewt/releases/tag/v4.1.7)** and **[InfiniTime 0.7.1](https://github.com/JF002/InfiniTime/releases/tag/0.7.1)**. There was no recovery firmware at that time.
