ADAFRUIT BLUEFRUIT FEATHER NRF52840: CANT FLASH BOOTLOADER

by matead on Tue Oct 26, 2021 12:35 am

Hi. I have an Adafruit Feather nRF52840, and I have tried to upload one of the examples but whenever I try to do so, I get this error

Code: Select all | TOGGLE FULL SIZE

I then try to update the bootloader, but I get this error

What the hell is going on? I'm using Windows 10 (64-bit) with the latest Adafruit libraries that the Arduino IDE had listed.

Thanks.

Okay, after hours of troubleshooting, I managed to update the bootloader by using "feather_nrf52840_express_bootloader-0.6.2.zip" from your GitHub and using the ZIP within it with "adafruit-nrfutil.exe".

So that's updated now to
    UF2 Bootloader 0.6.2 lib/nrfx (v2.0.0) lib/tinyusb (0.10.1-293-gaf8e5a90) lib/uf2 (remotes/origin/configupdate-9-gadbb8c7)
    Model: Adafruit Feather nRF52840 Express
    Board-ID: nRF52840-Feather-revD
    SoftDevice: S140 version 6.1.1
    Date: Sep 10 2021

However, I still cannot upload the Arduino examples. I am getting this error.

Okay, I had the wrong board selected it seems from the Arduino menu. Seems to be working now. Hope this helps anyone else who runs into this problem.
