Cant Flash a Feather m0 bluefruit le

by wcolumbia on Thu Sep 07, 2017 3:30 pm

Hello all. i have 2 Feather m0 Bluefruit le modules. they both had micropython installed. I was able to install ciruitpython on 1. the other wont go in to dfu mode when double pressing reset button. the reset button works. any ideas why it won't go in dfu mode?

thank you

Try connecting the DFU pin to GND before you connect power:

tried that. i think that forces a dfu mode for the BLE module. I'm trying to flash the m0 chip.

thanks for the reply

Ah, the SAMD21 doesn't have a DFU mode, just a bootloader.

You should be able to upload the CircuitPython firrmware with bossac, as shown on this tutorial page:

Yes, i know how to use bossac. in order for bossac to work and recognize feather m0 you have to double press the reset button. then the D13 led pulses. i have 2 feather m0,s. Bossac works on one of the feather m0. but not the other. i can double press the rest button on one D13 led pulses but not on the other.

thank you.

Good Morning, is thier a way to trouble shoot why the double press on the reset button on 1 of my Feather m0 ble modules doesn't function properly?

thank you in advance.

We're troubleshooting a driver problem on Windows 7 that causes double-click not to work properly. Are you using Windows 7 or 10? If so, could you try the procedure described here: https://learn.adafruit.com/adafruit-fea ... boards-faq? Thanks; let us know how it works out; we're still trying to diagnose the exact cause.
