Computer Rejecting Device

Post by patrickkistler »

Upon downloading the bootloader for the feather nRF52840, I was trying to run the device using the Arduino software on a windows 10 laptop. I had trouble getting it to even recognize that the device was plugged in via USB. Searching for the correct driver and bootloader, I found the source on Adafruit's website, however I was faced with several issues along the way. I want to know what driver I need to use and why my computer deletes the bootloader files because it believes they are a virus.

I doubt the computer deletes these files on behalf of windows itself. Is it possible that you run another service on top of that, some virus/malware suite? Can you turn that off temporarily? I also see many downloading unzip tools, and running into troubles with that. So if you have winzip or BANNED, and did not pay a licence, throw them off your system as they are of no use then and make opening a zip file a total frustration.
This is the place about the bootloader:
https://learn.adafruit.com/introducing- ... bootloader
This file:
https://github.com/adafruit/Adafruit_nR ... -0.5.1.zip
or if you have the one with all the sensors:
https://github.com/adafruit/Adafruit_nR ... -0.5.1.zip

You should be able to download zip files, open them in the Explorer, and drag the .hex file out of it.
The other thing that could cause issues is the .exe that does the actual install of the bootloader. Again, usually you should be able to click pass a Windows Defender warning and have it run anyway, but this can be blocked out by system administrators. On our school downloading .exe is made impossible.
Usually updating bootloaders is not needed very often, so maybe you can use another computer if the problem persists.
