clue bootloader upgrade

Post by Max47 »

I have an Adafruit CLUE - nRF52840 Express with Bluetooth LE PID: 4500 ordered on September 18, 2020,
the board is recognized on my Macbook Pro, I could double click and ge the CLUEBOOT and the INFO_UF2.TXT gives me the following:
UF2 Bootloader 0.3.0 lib/nrfx (v2.0.0) lib/tinyusb (legacy-1500-g23df777b) s140 6.1.1
Model: Adafruit Clue nRF52840
Board-ID: nRF52840-Clue-revA
Date: Jan 13 2020
I tried all the suggestions in every corner of your learning guides and forums, but I could not find the solution to upgrade the bootloader.
I want to use the clue with CircuitPython but with an actual version, please help me. Thanks!

The second page of the getting started tutorial instructs how to update the bootloader, as the very first thing to do.

It worked without any problem for me. Try again, following the directions very carefully.

If it continues to fail, post complete details of what you did and what went wrong, and someone can help.

Which update method were you using? The guide shows 3 different options.

What happened when you tried the process?

On windows I could not even get the board to switch to CLUEBOOT. I tried the command line option on Mac and finally I succeded to install the bootloader!!! After this I could also see the clue on windows and on double click even the CLUEBOOT and I could successfully move the latest CircuitPython release on the board and everything works now. Thank you all for giving me confidence and support!!!

this dis the magic:

Code: Select all

pip3 install --user adafruit-nrfutil
download:
	clue_nrf52840_bootloader-0.8.2_s140_6.1.1.zip

ls /dev/cu.*
	/dev/cu.usbmodem14201

Downloads/adafruit-nrfutil --verbose dfu serial --package Downloads/clue_nrf52840_bootloader-0.8.2_s140_6.1.1.zip -p /dev/cu.usbmodem14201 -b 115200 --singlebank --touch 1200
