I am using STM32F427VGT6 in one of my projects. An external phy KSZ8041NLI-TR is interfaced with MCU via MII interface. A 6 pin JTAG connector is used for programming and debug purpose. High speed crystal ECS-250-10-36B-CTN-TR having 10pF load capacitance is used. NX3215SA-32.768KHZ-EXS00A-MU00525 is used as low speed crystal. All the unused pins are left floating. Please go through the attachment. Is there any problem while keeping the unused pins floating? Kindly go through the attachment and let me know any additional connection is required for the proper operation of MCU.
