Arduino has happily been an exception until this happened in the middle of an otherwise (and up until) successful session of writing and uploading code. I hate win 10 with a passion because connecting anything other than a g-d cellphone is usually an enormous exercise in frustration. I just cant get win 10 to let me use the com port to upload a program. The UNO powers up, is recognized on the com port, and returns the board info when requested from under the "tools" heading. I grabbed a new from package UNO and I can't even load blink on it. Different usb cable, numerous restarts ,reload drivers ect. I have since tried all of the easy fixes. This report would have more information with Maximum is 2048 bytes.Īvrdude: ser_open(): can't open device "\.\COM3": Access is denied. Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Sketch uses 930 bytes (2%) of program storage space. Error message as follows:Īrduino: 1.8.9 (Windows 10), Board: "Arduino/Genuino Uno"
Win 10, Uno R3.… I was uploading no problem probably more than a 1/2 dozen times and finally figured out a code error and then on an upload attempt the upload failed and hasn't worked since.
