[avrdude-dev] Fwd: Problem to Connect to jtag2 vi usb

[avrdude]

Hallo Listmenbers. 

Long time i was active on this list. 

I have
a Problem, which i didn't find a solution at all the forums. 

I tries:


root# avrdude -cjtag2 -px128a1 -u -Pusb -Uflash:w:SGG.1.1.mc1.hex 

0
up to 100 times I get:

 System
wide configuration file is "/usr/local/etc/avrdude.conf"
 User
configuration file is "/home/axel/.avrduderc"
 User configuration file
does not exist or is not a regular file, skipping

 Using Port : usb

Using Programmer : jtag2
avrdude: jtagmkII_open()
avrdude:
usbdev_open(): did not find any USB device "usb"

But then its running
throu without a Problem!

I'm now in prototyping state, so I do it like
this:

while ! avrdude -cjtag2 -px128a1 -u -Pusb
-Uflash:w:SGG.1.1.mc1.hex; do
 echo again
done

But it takes up to some
100 loops!

you have any idea what's going wrong???

thanks
