The chip +itself has a ROM that allows the flash to be programmed from 3.3V +serial port or from USB. + +To enable the ROM, the "erase" pin is held high during a reset, which +erases the flash contents, and causes the ROM to run. + +The code at https://github.com/shumatech/BOSSA can be used to program +the SAM4. It is necessary to use version `1.8.0` or higher. + +To flash an application use something like: +``` +bossac --port=/dev/ttyACM0 -b -U -e -w -v -R out/klipper.bin +``` + SAMD21 micro-controllers (Arduino Zero) ======================================= |
