[avr-chat] avrdude fails to write STK500 & AT90S8515

[jmonreal]

Hi, I'm new in the field. I have just acquire an STK500 AVR Starter Kit. It
comes with AT90S8515 micro-controller. I work only under GNU/Linux and I've
followed the steps to install all necesary software to work with this
"board". The thing is I keep getting the same error with avrdude

$ avrdude -p 8515 -c stk500v2 -P /dev/ttyS0 -e -U flash:w:simple.hex:i

avrdude: AVR device initialized and ready to accept instructions

avrdude: Device signature = 0x1e9306
avrdude: erasing chip
avrdude: reading input file "simple.hex"
avrdude: writing flash (96 bytes):

***failed;

and it goes like that until 100%

then,

avrdude: 96 bytes of flash written
avrdude: verifying flash memory against simple.hex:
avrdude: load data flash data from input file simple.hex:
avrdude: input file simple.hex contains 96 bytes
avrdude: reading on-chip flash data:

avrdude: verifying ...
avrdude: verification error, first mismatch at byte 0x0000
         0x0c != 0xff
avrdude: verification error; content mismatch

avrdude done.  Thank you.


I've been Googleing but nothing, hope you could help, Thanks.

PS: I've tried windows but avr studio told me something about ISP frequency
mistaken :s

this is what i get with avrdude -v option
