This is for :spark: core owners who would like to upgrade their factory firmware from V01 to the V02 that is on the new core manufactured! Continue only if you understand the possible risk of ending up with a non-functioning core (which still can be revived) which you have to troubleshoot The wa…

@kennethlimcp you know what they say “it’s hard to make things idiot proof since idiots figure out new ways to break things every day.” :slight_smile: Since this is my 1st micro controller I did not have any of the prerequisites installed on my machine, this picture might help explicitly point out …

It’s technically the core but 2 parts: Internal flash and external flash. Make sure the .bin files are at the directory where dfu-util.exe is. T:\SPARK-core\dfu07 for your case and try again :slight_smile:

Hi @peetersm , I’m guessing you hit another gotcha on Windows, some operating systems require elevated access to write to devices using something like dfu-util. Try running that process in an Administrator Command Prompt, and maybe that’ll fix it? :smile: Thanks, David

thanks for the continued help. I do have the files in the same directory (thanks for checking), and even when running CMD as admin I am getting the “can not claim interface”. I am trying to do some reading seems like this error means dfu might be seeing more than one interface. But not sure since d…

@peetersm , It’s right to show up ‘2 devices’ . You can see the alt= there’s 0 and 1. Same device (spark core) but 2 alternatives :smile: 0 for Internal flash and 1 for External flash. Got some free time? We can try to fix this over chat and post the solution here :wink:

I am all set up, had the wrong DFU driver. thanks to @kennethlimcp I am now on V2. once I got the right version to reinstall the DFU driver for windows http://zadig.akeo.ie/ It was like night and day. thanks again!!!

So i decided that a Tutorial for how to setup DFU-driver on windows is really gonna be handy. > https://community.spark.io/t/tutorial-installing-dfu-driver-on-windows/3518/2

Is there a list of improvements for firmware V2? My spark is disconnecting from wifi frequently, I’m hoping this will fix that issue.

Getting an error "Error during download get_status" http://pastebin.com/ws91MCPm Driver is OK http://screenshots.ryotsuke.ru/scr_79dc50aa02fe.png @kennethlimcp ? P.S. Firmware DID update though. That’s weird P.S. With updated reset software it does not connect to wifi anymore =_=
