STM32G070 Flash Library for Bootloader

[GSing.1]

I would like to write a bootloader for STM32G070 which I can use across projects. Is there any flash library for STM32G070 available which I can use and write a bootloader? OR does STM32G070 has inbuilt bootloader which I can call by sending respective HEX codes via UART?

Giving a brief on Bootloader mechanism implemented on this MCU will of great help.

Thanks

The HAL example library (unpack CubeG0 repository) should have FLASH demos for assorted boards.

AN2606 should described the boot loader capabilities, AN3155 the UART protocol
