Get the bootloader from https://micropython.org/resources/firmware/bootloader-xplained-pro-v3.16.0-15-gaa52b22.hex. +2. Connect your board to the debug port. A drive with the name XPLAINED +shall appear. +3. Copy the Intel hex file of the bootloader to that drive. +4. Connect your board to the target port. A drive with the name SAMD21XPL should +appear. If not, push reset twice. Then it should appear. If that does not +happen, the bootloader was not properly installed or is not compatible. +5. Copy the MicroPython firmware, a .uf2 file, to the SAMD21 drive. When the SAMD21 +drive disappears, MicroPython is installed. + +From now on only steps 4 and 5 are needed to update MicroPython. You can use the +usual methods to invoke the bootloader, namely: + +- Push Reset twice. +- Call machine.bootloader(). +- Use the touch 1200 procedure by switching the USB baud rate to 1200 baud and back. + +At the above link above there are as well .uf2 versions of the bootloader +which one can install using steps 5. and 6. above once a .uf2 capable +bootloader is installed. |
