I'm designing my own board based on the FRDM-k64F. In the debug phase I will use the SEGGER Base debugger.
After the board will be operational and mass produced, is there a way to flash the ARM without the SEGGER (since it will be placed in a hard to reach area)?
For example, I'm communicating my board via UART (from external host 10 meters away, using USB to RS485, and in my board, using RS485 to UART). Can I flash through this already-exist connection?
I prefer not placing the MK20 for OpenSDA as I do not know the complexity of designing the OpenSDA inside the MK20 (or is it copy-paste of exist code?)
