M0 Basic Proto #2772 : new generation?

by Patouf on Thu Feb 14, 2019 1:42 am

This post is related to the following thread, which helped me solve one issue. I could not program my M0 Basic Proto boards and reinstalling the recommended drivers allowed me to program them.

Now, I observe discrepancies between two M0 Basic Proto (Adafruit board #2772), which seem to have a different assembly batch number. I attach 2 pictures. The old one seem to come from batch #0818, the new one from batch #4818.

Both can be programmed with Arduino software and a USB cable, but they do not behave the same way. When I double-click the RESET button on 0818, I understand the bootloader mode is activated since its red LED slowly flashes. When I double-click the RESET button on 4818, window FEATHERBOOT pops up (see following snapshot). I also see CIRCUITPY from time to time (I do not remember in which circumstances).

I purchased 50 M0 Adaloggers and 10 M0 Basic Proto in the last year and I have never seen this FEATHERBOOT window before. I made plenty of tests on 0818 to be sure that my code works well and now I fear that 4818 will not work as well.

Last week, I purchased 60 M0 Basic Proto, which are from batch #4818, and everytime I upload a program on a new board, Windows installs 6 drivers (Feather M0 and others), which can be quite time consuming.

Are those 4818 boards reliable? Do the Adafruit drivers still need a revision? I fear that I may encounter considerable issues with those ...

I use Windows 7 and programmed with Arduino 1.8.5.

there's a new bootloader, which we find works a lot better - it is completely back-compatible with the old version, and now allows drag-n-drop programming!

windows drivers are here

we have used this bootloader for a few years now (on other boards) it is extremely reliable
