I tried changing the main() code, but ended up deleting something that caused the board to no longer be recognized via USB. Is there any way to hard reset the SparkFun Variable Load?
Please clarify: if it is the main() function for a sketch (in main.cpp), it will not change the bootloader. You may need to make sure to reset the board, just before you upload a new sketch.
or did you change anything to the SVL code itself and burned that bootloader to the board?
