Hello,
An ST employee wrote this article: https://community.st.com/t5/stm32-mcus/how-to-use-the-stm32n6-in-overdrive-mode/ta-p/810926
where you can increase the voltage to the STM32 core to get higher performance. I have 3 questions regarding this article.
1- it says you need to use PF4 to kick the processor in overdrive. Does PF4 need to be used (ie special function) or can any GPIO be used? (ie is PF4 just used on the STM32N657-DK board)?
2- Since ST published this article, are there any benchmarks or data (ie bus speeds) that were recorded when the core voltage was increased from 0.8V to 0.89V. It would be nice to know if we should implement this mod, or its really not worth it. What about reliability over time?
3- I purchased the STM32N657-DK development board. Is the source code available for the demo on the board, and if so, where can I download it. It says by default the DK is not in overdrive mode, so I would like to modify the code to enable the overdrive.
thanks, Matt
