… seems I have that problem too on my first board (Seeduino v328 06/23/2009).
LED without reference blinking fast, TX most times also blinking fast, programming from arduino-0021 leads in no reaction (no indication of sucessful / not succesfull programming).
Seeduino board is recognized as Port3.
Could somebody help me with AVRdude instructions: got problems with step 5.
With command line “=l114” / “=I114” I get error message:
AVRDUDE.EXE: invalid portname lpt1: use ft0 - ft9
With command line “-c SeedStudio -P ft0 -p m3” I get error message:
AVRDUDE.EXE: Can’t find programmer id “SeedStudio”
I am not in recommended directory (d:…), instead C:\FixSeeeduino_v328\ - might that be a problem?
Seems this might not be the ideal re-start into uC - have not played with that for the last 15 years…
