Hello, I am using stm32f769 bga package. We accidentaly connect VDD12DSI pin to VCAPSDSI pin and connect them to 3.3V VDD. We only gave power to the circuit for a few seconds. Could it damage the MCU? And if I disconnect these two pins and floating, will it work? Do I have to connect them to each other? Is there any way out?

Hello!
The problem is , VDD12DSI has a maximum input voltage 1,2V . So yes, the overvoltage on this pin is possible to caused a damage to MIPI-DSI section of chip or an
extensive damage
or nothing!.The only way to see if you have damage, is to follow first the DataSheet about connection of theese pins , and after to check the functionality of MCU .
