Hello everyone, Is there any register to proceed to know the product of the STM32. Best regards.
There might be a DBGMCU ID register, and you could look at the AHB/APB RCC registers, and other peripherals. How those behave, and values at reset will be rather telling.
Within a given family the boot rom contains flash and ram sizes, and manufacturing data.
It might take a little work, but it shouldn't be too hard to figure out what family/architecture you are working with.
