minipov3 / avrdude / serial port

Post by bottom-dragger »

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

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

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.
