I've developp a small product based on STM32L051, and we have to start production, 100 product for the moment.
What is the best way to program STM32 after PCB mounting :
- using STlink tool, connect each board and download hex file
- using 5 or 10 Stlink in paralell?
What about about powering for programming? is it possible to use Power Pin from STlink tool because the battery isn't on the board in the factory?
