What went wrong?

[Waycoolman619]

Yesterday I was able to upload a sketch today I found the boards in the Arduino IDE 1.6.7 were not there so I reinstalled them but I get this

Arduino: 1.6.8 Hourly Build 2016/02/16 05:07 (Windows 8.1), Board: "Digispark (Default - 16.5mhz)"

Board digispark-tiny (platform avr, package digistump) is unknown

Error compiling.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.


** it is 1.6.8 now because I tried updating the Arduino IDE
The drivers are fine my computers sees it plugged in?

Anybody know whats wrong? Im stumped, I guess I could upload using ISP but Im just learning how.

FWIW I had same issues w/ 1.6.7 and ended up using Arduino 1.6.5 - maybe history repeating itself?

I'm seeing the same thing, right when Oak showed up for install...

[digistump]

This is a known issue with Arduino 1.6.6+ (not with the Digistump files) - that shows when you upgrade third party boards - you need to remove the existing digistump package files and reinstall.

Ok, took a lot to get this working, here's what I did the last time:

• Uninstall through boards manager
• Exit Arduino
• Remove contents of .arduino15/staging/packages (I had a CRC doesn't match error)
• Remove .arduino15/packages/digistump
• Reinstall boards through boards manager
• Restart Arduino

Created an account here just to say I had the exact same problem and this solved it for me, so thanks for that

Where are these ".arduino15" files? I am using Arduino IDE 1.6.9 in Windows and am having this same problem and error, but I don't see these files anywhere. (I checked my sketch directory and C:\Program Files (x86)\Arduino)

After a good 45 min googling and searching around, I found the folders, and following the above instructions works! I can now upload to my digispark!

I am using Arduino 1.6.9, in Windows 8.1.

Here are the folder locations (referenced above) on Windows, where "Gabriel" is my username:
1) C:\Users\Gabriel\AppData\Local\Arduino15\staging\packages
   -delete all contents of this folder
2) C:\Users\Gabriel\AppData\Local\Arduino15\packages\digistump
   -delete this entire digistump folder

Very old thread I know, but wanted to post a thanks. Same issue, now resolved with the advice here.  I'm on IDE v1.8.5.
