Circuitblocks upload error


On Spencer i had time to time an upload error while making my own programs.

Now on Jay-d it is systematic, i tried several times all the demo programs, none of them was able to be uploaded.

I’m running CircuitBlock 1.4 on Windows.

Anyone had the same problem ?



I just send error report 460.


Looking at the report, this looks like a driver issue. With JayD plugged in, please open the device manager, find the “Silicon Labs CP210x USB to UART Bridge (COMX)” under “Ports (COM & LPT)”, right click it, select “Update driver”, and in the new window click “Search automatically”. This should update the drivers and uploading should work. If the error persists, please contact us at to get in touch with our support team.

I checked, the driver is up to date :confused:

I send you a mail.

Okay, we will solve this by mail. Thank you for your patience. :slight_smile:
