Hi, I have chosen STM32F072RB for our project and I have use it in design. But now we must store about 128-byte data for the calibration of our device. STM32F072RB’s flash is 128K. it is too big for this application. So, I want to use its spare space to store these calibration data (128 bytes) and save an extern flash.
Now my issue is, how could this MCU store the data to its own flash?
