Thanks for the suggestion. As a result, I have good news and bad news. First, removing the conductive foam did indeed solve the problem with the PI shutting itself down. However, as I followed the steps for getting started with the Arduberry on your web site, I encountered what appears to be a serious error once I tried to run Blink. I believe all of the settings are correct, including board, port and programmer. And I am using the “compile using programmer command” in the file menu to upload the sketch.
However, while the program appears to compile OK, when the PI tries to verify the data written to the flash card, I receive an error, specifically- avrdude: verification error content mismatch, and then a memory location where it did not read back the correct info. I have checked a number of web sites on this error, and some say that it represents a problem with the board that is not fixable by the user, others prescribe the use of a third party software to fix it. Since I am dealing with the unique Arduberry version of the Arduino, I need to know if there is a Dexter Industries recommended fix for this issue.
Thanks so much for your assistance.
