STM32L072 UART bootLoader

[Sshan.1]

I want to Implement the UART bootloader to the STM3272cz Microcontroller and flash the code with STM32cube programmer .I want to understand the STM32 cube programmer UART protocol used here for flashing the Bin file to the micro controller .

Any suggestions please help me in understanding the concept

AN2606 can be understood as the central point for all bootloader questions and also mentions the associated documents in section 2:

• AN3154: CAN protocol used in the STM32 bootloader
• AN3155: USART protocol used in the STM32 bootloader
• AN3156: USB DFU protocol used in the STM32 bootloader
• AN4221: I2C protocol used in the STM32 bootloader
• AN4286: SPI protocol used in the STM32 bootloader
• AN5405: FDCAN protocol used in the STM32 bootloader

AN3155 is probably the appnote you are interested in.

Good luck!

Hi Peter ,

Thanks for your reply and The AN3155 USART protocol is used same in the STM32cube Programmer also ??Please confirm
