Resolved! Is STM32F412VET6 on-the fly firmware update possible?

Hello,I'm working with a STM32F412. In my process, the STM32 will receive a firmware. The idea is to flash this firmware (that is in RAM) to the STM32 for it to execute after a reset. I don't know if it is possible.If it is not, what are the properti...

Hi. I have a query, related to the global interrupt of the Uhart. Is there any way we can enable more than one interrupts for a singal uhart.

Actually I am using a single interrupt to receive, data from another processor in two different arrays. Due to this scenario and interrupt being called at two times in different arrays, only the first array receive interrupt accurately.
