I2C bootloader code sequence
Figure 1. Bootloader for STM32 with I2C
Note:
The I2C slave address for each product's bootloader is specified in the AN2606.
Once the system memory boot mode has been entered, and the STM32 microcontroller has
been configured (for more details, refer to your STM32 system memory boot mode
application note), the bootloader code begins to scan the I2C_SDA line pin, waiting to detect
its own address on the bus. Once detected, the I2C bootloader firmware begins receiving
host commands.
