Description

Initial DSerial programming is done with the PROG connector. Once the bootloader is on the microcontroller, it can be programmed from DS or any other interface the bootloader supports.

Initial Programming

Note: This is only required if there's no bootloader on the microcontroller.

Initial programming requires a programming cable from Silicon Laboratories. A modified ToolStick is the cheapest way and can also be used as an in-circuit debugger.

Programming via Bootloader

Since the microcontroller is self-reprogrammable, it's possible to use a bootloader that can receive the program from the supported interfaces and put it into internal flash. It's then possible to jump to that program.
