Hi,
i just switched over from uisp to avrdude-5.0-BETA ("make" for 4.4 did not
execute properly).
I added a new programmer in avrdude.conf:
programmer
id = "dapa";
desc = "What 'uisp' understands as 'dapa'";
type = par;
vcc = 3;
reset = 16;
sck = 1;
mosi = 2;
miso = 13;
;
I doubt the value for "Device signature" that i read on the ATMega128,
which reads as 0x000102 whenever i connect to the target the second time.
When i connect an AT90S2343, the device signature looks ok to me as
0x1e9103
When i connect with avrdude the first time, i read the device code 0x1e9702
which looks ok to me. When i just re-type the same command, i get 0x000102.
This is the same problem that i experienced using "uisp".
As uisp and avrdude work on an AT90S2343, the programs and the settings and
the basic hardware seem to be ok, the problem seems to be related to the
ATMega128 and the hardware it is soldered on.
Does this look like some standard problem? What could it be?
Could it be that some internal pull-up/pull-down or whatever else is blown?
Can i use some more conservative settings for timing? I already tried to
increase predelay and postdelay from 1 to 5 and also to 100. No change.
Whenever i connect the second time, i get the problem described.
Are there any other values i can try?
The basic communication seems to work ok, as the values are not just 0x00
or 0xff.
There is no crystal soldered on the PCB.
The supply voltages look ok.
PEN is connected to GND.
I don't connect directly to the parallel port but use a PCB inbetween for
proper signal levels.
Is there any more information i can give?
Has anybody got a hint for me?
Best regards,
Torsten.
