Hi....Presently am working with STM32L151VCT6.I would like to upgrade my system with STM32F107VCT6. My existing code will work with new STM32F107? or I need to build system configuration and initialisation routines from starting onwards to do??

You'll need to port/migrate the design. Pin configuration and clocks likely different.

Create a shell project for the new platform, and then merge and test a portion at a time.​
