Can we use ST Open BootLoader with STM32F446RE Nucleo board ?

[ST.10]

I've STM32F446RE Nucleo board, which i want to update in the field over USART.

Looks like ST Open Bootloader supports this already. However, the example shared is for STM32G0XX.

I wanted to know if we can use it(ST Open Bootloader) Out-of-box ? and if Not, then can we make minimal changes/port this and use it ?

Hello @Community member​ and welcome to the Community 🙂

You can customize OpenBL for other products series like STM32F4 series according to your needs:

• \STM32Cube_FW_G0_V1.x.x\Middlewares\ST\OpenBootloader
• \STM32Cube_FW_G0_V1.x.x\Projects\STM32G0C1E-EV\Applications\OpenBootloader

I recommend that you refer to the following resources:

• How to use the ST Open Bootloader for STM32 Microcontrollers
• USART protocol used in the STM32 bootloader (AN3155)
• FAQ STM32 boot process 
• GitHub - STMicroelectronics/stm32-mw-openbl: Provides the Open Bootloader library, part of the STM32Cube MCU Component "middleware", for all STM32xx series.
• AN2606 Application note "STM32 microcontroller system memory boot mode", you find related information to STM32L4xx bootloader.
