I just got three KTA-223 “Relayduino” boards from SF and they do not program. These are basically Arduino Duemilanova boards with the Arduino bootloader on them and KTA custom firmware. I set the auto-reset jumper and still the compiler says that “avrdude.exe: stk500_getsync(): not in sync: resp=0x00”, like the board isn’t listening. Previous rev 12 boards that I have program fine, so my setup is good. These are rev 14 boards.
I suspect Ocean Controls has changed something in their bootloader or may have some fuse settings wrong. We’re looking into this now and will update when we have more information.
OK, it turns out that Ocean Controls did ship a few units with the wrong fuse settings. Using a AVR programmer, change the fuses to the following values and that will restore the ability to program the KTA-223 via Arduino.
LOW = 0xFF
HIGH = 0xDA
EXT = 0xFD
That should restore the ability to re-program the KTA-223 through the Arduino IDE.
