Bootloader Firmware Installation

If you are installing the bootloader because you think you deleted/corrupted it by uploading a bad sketch in Arduino, check first by entering the bootloader manually (double-press reset) as it is probably just a broken sketch.

Bootloader Installation Using the Arduino IDE

  1. If you do not already have the Electronic Cats SAM D|L|C Core installed, see SAM D|L|C Core Installation above.
  2. Plug in the board. The bootloader must be running to (press reset twice within 500ms).
  3. Plug an Atmel ICE into USB, then connect it to the powered board. A green LED should light on the Atmel ICE.
  4. Click Tools->Programmer->Atmel ICE.
  5. Click Tools->Board->Electronic Cats Board (or whichever board you are using).
  6. Click Tools->Microcontroller and select your MCU (if menu present).
  7. Click Tools->Burn Bootloader. Ignore any messages about not supporting shutdown or reset.
  8. Continue with driver installation above.

A running sketch may interfere with the bootloader installation process. Be sure you are running the existing bootloader or using a blank chip.

Bootloader Installation Using Another Tool

See bootloaders/zero/README.md for information.
