New Leonardo - Will not load Blink

Development Tools Uploading
1

First Leonardo I have owned. No problems with any of my UNO or MEGA boards in 7 years. All work fine out of the box.

Connecting to programmer: .
Found programmer: Id = "CATERIN"; type = S
Software Version = 1.0; No Hardware Version given.
Programmer supports auto addr increment.
Programmer supports buffered memory access with buffersize=128 bytes.

Programmer supports the following devices:
Device code: 0x44

Any help appreciated.

does you try usb connection? show your setup

Hi @dre3rd. The output you shared is the normal output from a successful upload to a Leonardo board when using Arduino IDE 2.x.

This output is produced by the AVRDUDE tool the IDE uses to upload sketches to the Leonardo. If you were using Arduino IDE 1.x before, you might be accustomed to not seeing any output at all from the uploader tool when uploading without the "Verbose output" option enabled in your preferences. Arduino IDE 2.x uses a more flexible approach where any output from the tool is printed, giving each boards platform developer control over what output should be printed depending on the "Verbose output" option setting rather than forcing no output at all as was done in Arduino IDE 1.x.

Although this output is not so interesting to the average Arduino user, for some reason the AVRDUDE developers thought it was important enough that it should be printed even when the verbose flags are not added to the upload command.

You might also be alarmed by the red coloration of the text. This is also at the whim of the AVRDUDE developers. They decided that output from AVRDUDE should be printed on the standard error stream ("stderr") rather than the standard output stream ("stdout"), as is more common. Arduino IDE prints all tool output received from stderr in red. The IDE doesn't have any way to know that in this case the avrdude output is not indicating any error/warning condition.

So if this text gave you the impression that something was wrong, don't worry. You can get back to your Arduino project. If you are having some problem, please provide a detailed description of it so we can help you out:

  • What did you do?
  • What were the results you expected from doing that thing?
  • What were the results you observed that did not match your expectations?

Thank you. I will try another sketch with serial output and watch results.
