Hi all, I have a problem that haunts me for a week, I kept my arduino mega 2560 inactive for a month ... I've always used with an iMac, after a month I tried to connect to a laptop with windows vista ... I tried to upload a sketch of example (blink) and before she could finish loading the sketch ... upload the program stops and gives me this error message:
avrdude: stk500v2_command(): unknown status 0xc8
avrdude: initialization failed, rc=-1
** Double check connections and try again, or use -F to override**
** this check.**
avrdude: stk500v2_command(): unknown status 0x01
avrdude: stk500v2_disable(): failed to leave programming mode
Now it does not work with the iMac ... I selected the tab in the menu of the IDE and also the type of programmer ... has always worked out well ... but as soon as I connected the laptop has happened all this mess ...
could be the BOOTHLOADER?
