Sorry to have to post such a tired old problem that has been well covered already but research doesn’t help. Here’s what I have tried so far to solve my problem of being unable to upload from Windows 10 Arduino IDE App to the Uno Wifi Rev 2. The problem is I get:
Sketch uses 1482 bytes (4%) of program storage space. Maximum is 32256 bytes. Global variables use 196 bytes (9%) of dynamic memory, leaving 1852 bytes for local variables. Maximum is 2048 bytes.
An error occurred while uploading the sketch.
then 10 of these: “avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00”
So far I:
- Checked that the Arduino is receiving power. It is. It’s actually running a sketch I was able upload using the online code IDE. The sketch prints “Hello World” to the serial monitor every 10 sec and it’s currently doing that. Problem is I can’t upload almost the same sketch (this one says “Hello PC” using the Arduino IDE App on the PC.
- Checked that the Arduino device driver is installed. Device manager lists the mEDBG Virtual COM Port (COM3) as being installed. Checked for updates and it’s current. Driver Provider: Atmel Corp. Driver Date: 6/14/2013; driver version: 220.127.116.11; Digital Signer: Arduino AG. “Windows has determined that the best driver for this device is already installed.”
- Checked that the COM port is not being used by the online-version of the IDE or any other program by closing all programs, unplugging the Arduino Wifi Rev 2 from the USB port for 10 seconds, then plugging it back in, then starting up only the Arduino App and try uploading the new Hello PC sketch. Still get the same error and the Arduino is still printing “Hello world” not “Hello PC” to the serial monitor.
- Other clues: on the PC IDE App the IDE:Tools:Board: says “Arduino Uno Wifi” – correct, but IDE:Tools:Port: says “COM3” and that’s it. While that is the correct (and only) port; on the Mac the IDE:Tools:Port is labeled with the port number followed by the board ID. One other difference is that on the Mac the IDE:Tools:Get Board Info: shows the correct board info. On the PC, IDE:Tools:Get board info: shows
BN: Unknown board
SN: Upload any sketch to obtain it
Ok, maybe once I get a sketch uploaded it will display the correct board info.
I can’t go back to the Mac because of a different problem that forced me to the PC, namely the inability to install the Safari plugin for the Arduino Create Agent, which has been posted here but as yet unresolved. Thanks.
