[avrdude-dev] STK500v2 speed problems

[Klaus Rudolph]

Hi all,

I today program a at90s8515 a few times and need around 40 sec to write
and 10 sec to verify. After a few programmings I now need 250 sec. Why?


I use:
avrdude -p 8515  -c stk500v2 -P /dev/ttyS0 -e -v -U flash:w:cservo8.srec

         Programmer Type : STK500V2
         Description     : Atmel STK500 Version 2.x firmware
         Programmer Model: STK500
         Hardware Version: 2
         Firmware Version Master : 2.01
         Topcard         : Unknown
         Vtarget         : 5.1 V

         Varef           : 5.0 V
         Oscillator      : 3.686 MHz


What I am doing wrong? What can I change to get old timings?
I am a bit confused about that problem. Is there a problem with the
device, parameters inside the stk500? Some corrupted init files?

Thanks!
 Klaus
