What is the bootloader?

A bootloader is a piece of code in firmware that runs when a device is powered. ​

Its primary function is to initialize the device’s hardware, memory, and other essential components to prepare it for the application firmware to run. ​

In other words, the bootloader acts as a bridge between the hardware and the main firmware, allowing the device to start up correctly and load the main software.​

The bootloader can be updated only by burning the firmware with a burner (done in the factory). When a user upgrades a device via FOTA, only the application of the device is being upgraded. It does not change the bootloader version.
