How to go from a Nucleo board to a production board

Hi,

I developed a prototype using a Nucleo-F207ZG which has a STM32F207ZGT6U (144-pin) micro-controller and mbed OS 5. My question is how do I go from the prototyping stage to the production stage?

  1. Can I use the same range of micro-controllers ( STM32F207) but with less pins (100-pins for example)? If so, what files do a need to edit?
  2. How do I upload the code without ST-Link? Can I use USB interface and upload a hex file using DfuSe?
  3. If I used the USB port, I'm going to need an external crystal. What files do I need to edit in in order to run mbed OS 5 of an external crystal?

Thank you
