Hi,
IDE freezes when attempting to upload Blink sketch (or any other); it need to be killed. Host computer becomes unstable; reboot is necessary.
Following error is shown:
Found programmer: Id = "sensor "; type = 0
Software Version = s.e; Hardware Version = n.s
avrdude: error: buffered memory access not supported. Maybe it isn't
a butterfly/AVR109 but a AVR910 device?
Details:
Host computer: Mac Mini with OSX Mavericks
Board: Leonardo
Purchased this Leonardo a few months back, tried a few sketches and worked perfectly. Since then, I upgraded my Mini to Mavericks.
Yesterday I downloaded JDK 7 SE from Oracle, and the new IDE 1.5.7 BETA for Java 7. The program loaded fine, and the Serial Monitor also worked (the sketch in memory prints an analog measure of light onto a photocell). When I tried to upload some changes to the sketch, the error presented above occurred.
Since then, I uploaded again the IDE 1.5.7 for Java 7 one more time; removed JDK 7 and went back to the original Java 6 (1.6.0_65 according to command line "java -version") then installed IDE 1.5.7 for Java 6; and finally got the original IDE 1.5.6 out of the trash can. All of this attempts give the same error.
One more detail. I assembled a real time clock module (DS1307 from Adafruit) and connected it (this was before I tried to upload to the board). I noticed that either the Rx or Tx lighted dimly and the Leonardo seemed to have stopped working; so I may have a defective module. I have removed the module since then.
Any comments / ideas will be appreciated.
