Spark Core on Zerynth 2.0.4


I am using a Spark Core, when I upload I have gotten two messages:

[error] No answer to probe

made changes to bit per second, now getting…

[error] Can’t open serial: COM3

Help please.


Hi toyman,
thanks to join the Zerynth Community, in which platform you are using the Zerynth Studio? Have you tried to install the driver for the Spark Core device (both Standard mode and DFU mode)? Can you post the entire log error message?

Here a link to our documentation that could help you to fix the problem!

Let me know if everything works!!! :slight_smile:
