MicroPython Forum (Archive)

Hi everyone,

i am trying to load microPython onto the Feater M0 Adlogger board. I followed the instructions in this video/ guide:

https://learn.adafruit.com/micropython- ... 1/overview

I downloaded the recent firmware and bossac-1.7 from the GitHub

when I try to use ./bossac -e -w -v -R -p tty.usbmodem411 firmware.bin i always get "No device found on tty.usbmodem411"

One thing i noticed is that other then in the video my board falls out of bootloader-mode fairly quickly.
I am on a MacBookPro El Capitan Version 10.11.16

Thanks for the Help!

Can you post the full link to the guide you used? Abbreviated like this it’s not much use. (I’m confused because I’m not aware of any official release of MicroPython for SAMD21 yet. Any reason why you want MicroPython, not CircuitPython on that board?)

Are you sure tty.usbmodem411 is the right port or did you just copy that from the guide? If the latter, it may be named differently in your situation. Run ls /dev/tty.* to find what ports you have.
