I'm preparing for a KL03 design from our product dev group and I'm the guy who gets the production tools done. We will be programming the uP in a production environment and from what I've found the serial boot loader is the way to go. I will have a custom designed PCB for testing the product and I can easily add a serial port that the PC can use to program the KL03 directly but to do that I'd need a bootloader DLL and associated API documentation to make a PC app that talks to our internal database for programming parameters. The other way is to code the boot loader into the uP on my custom PCB using the low level bootloader protocol documentation and use it to program the KL03. The PC option would be much easier. Is the DLL and API reference available and if so, where would I find it?
