Hi guys!
As I can see you are all a very fast and flexible group! congratulations! But
before you make your next release, I want to call your attention to another
problem that I have encountered.
Every time after rebooting my windows XP system (running on Intel Celeron
500MHz, 256MB RAM) I have got a problem programming my microcontroller with
AVRdude using the parallel port dongle. When I start the programming, the first
few seconds everything works fine. But after having written to the AVR for some
seconds, AVRdude reports a program fail for every single byte. Also, if I
repeat programming - again after a certain time (not the same time) AVRdude
reports " ***failed; ". As often I repeat, AVRdude never can manage to program
the AVR fully.
What I do then, to get it work, is to read out the AVR flash memory. After this
I again try to program the AVR and - oh wonder - then it works without a
problem. This problem just appears after rebooting my system.
I now did a little test using the ppiwin.c file only. I modified it by
inserting a main() function so that I can run it by itself in order to control
the parallel output pins. Here the same thing happens again. After some seconds
the parallel port pins automatically change their states. I couldn't find out
so far, why. This seems to me is the same problem that appears when I use
AVRdude, because here after performing an AVR read out suddenly this automatic
change of port pin states doesn't appear anymore until the next reboot.
Does someone have a clue, what could be the problem?
Sorry for coming up with new problems all the time ;-)
