  • I have an issue with the programmer… I need to hold the reset button in order to make the programmer works. If I do not hold the reset button, I sometimes get the message ‘initialization failed, rc=-1’ and sometimes it starts to work but then I get ‘Yikes! Invalid device signature.’

No public wish lists :(
