I have a single hex file for STM32F and STM32G series. Can you suggest a way to identify if the microcontroller is a F or G series to load the appropriate code?

I went through the device electronic signature. I don't see anything specific by reading the register from which I can differentiate between F and G series

I imagine DEV_ID is different between the two, possibly at different memory locations. The reference manual for your specific devices will tell more. "STM32F" isn't too specific and covers a very large number of devices.

Thank you so much. MCU device ID register provides the part number that I was looking for.

There are also other ARM registers to determine the model/patch level of the Cortex-M type being used.

Thank you so much. It was very helpful.
