followed all the steps and loaded winavr shown on
http://www.ladyada.net/make/minipov3/software.html
type avrdude and got the response shown
then tried the test with minipov.hex
failed response
c:\make program-minipov
avrdude -p attinywe13 -P com1 -c dasa -U flash:w:minipov.hex
avrdude: ser_open(): can't open device "com1": Access is denied.
avrdude: serbb_setpin(): SetCommState() failed: The handle is invalid.
make: *** [program-minipov] Error 1
i went into device manager and com1 is enabled and dianostics said it is working properly.
the minipov3 works properly, according to the lights.
i'm perplexed and would appreciate any assistance you can provide.
thanks, joe

Re: minipov3 / avrdude / serial port
sorry, didn't go back far enough in the past messages.
com1 now works but getting another error msg
avrdude: AVR device not responding
avrdude: iniialization failed, rc=-1
Double check connections and try again, or use -F to override
this check
hints on where to look first? the solder joints on connector on the board?
moving ahead, slowly
thanks, joe

Re: minipov3 / avrdude / serial port
yeah. check the solder joints on the db-9 connector, the diodes and the resistors paired with the diodes. make sure the board is powered when you program it.
post in focus overhead pictures of the top and bottom of the board.
