Flash write error

[KnutKnutsen]

Hi everyone,

I've got my digispark pro (finally) yesterday, after 10 days of waiting due to german customs. (Not to mention the endless packaging phase ;P)

After soldering the headers, I already tried some examples, which were fully working. I also buyed one of the DigiLEDs and could execute the example from the wiki.

But then I tried to make a program that changes constantly the color of the LED. I (successfully) uploaded the sketch once, but there was no change of the color.

But the actual problem is, that if I try to upload some code, the programmer puts the following to the console:

Code: [Select]

Plug in device now... (will timeout in 60 seconds)
> Please plug in the device ...
> Press CTRL+C to terminate the program.
> Device is found!

>> Flash write error -1 has occured ...
>> Please unplug the device and restart the program.

Does anyone of you has some advices for me to fix the problem ? =)

Thanks and Greetings

Ok sorry,

know it works again. I don't know why. I just retried to upload the Blink sketch and it worked again.

But maybe someone can explain whats the "Flash write error -1" stands for ?!

Try a different USB port, I was having a similar problem but it appears the port I had been using was technically a hub not a root device and switching to a root port did the trick
