Correction to above:

For STK500:
avrdude -c stk500v2 -p m8515 -P /dev/ttyUSB0 -U hfuse:r:h-fuse.txt:r -U
lfuse:r:l-fuse.txt:r

For USB-ASP:
sudo avrdude -c usbasp -p m88 -U hfuse:r:h-fuse.txt:r -U
lfuse:r:l-fuse.txt:r -U efuse:r:e-fuse.txt:r

The lines above for each uC-programmer stores the fuse-values in files
that needs to be interpreted:
od -d h-fuse.txt | head -1 | sed -e 's/0000000 *//' | xargs -i perl -e
'$str= unpack("B32", pack("N",{})); $str =~ s/.*([01]{4})([01]{4})$/$1
$2/; print "$str\n";'
(see AVR Fuses HOWTO Guide)
This prints the fuse-values in binary form.

Alternatively for STK500:
avrdude -vv -c stk500v2 -p m8515 -P /dev/ttyUSB0 -F

Alternatively for USB-ASP:
sudo avrdude -vv -c usbasp -p m88

Here you get the fuse-values in hexadecimal form after a long text.

Sigh... *Only* 1GB *RAM* ?

It should work well with half of this. BTDT.

But I returned to vi, make, gcc-cross, uisp/avrdude under Linux, as this
is my basic OS. As I have to use Codewarrior from time to time, I am
happy that it works in "wine".

A note on USB programmers: All that use the serial port as a ... serial
port, will work fine. All that use bit-banging will not.

A cardbus LPT-card works well, a USP-LPT1 does not.

YMMV,
Falk

Thanks, this worked i Kubuntu 8.04:
$ avrdude -c stk500v2 -p m8515 -P /dev/ttyUSB0 -U hfuse:r:h-fuse.txt:i
-U lfuse:r:l-fuse.txt:i

In Asus EEE Linux I had to add switch -F.

My Asus EEE has only 1 GB RAM and might not work well with Virtual Box.

While I agree USB-serial bridges can be problematic, my experience
with the Atmel tools (all of them, including Olimex's clones with FTDI
USB interfaces) has been that they work very well over a USB-serial
converter.

                                     ^^^^^^^^^^^^

I've had many problems with the STK500 (and other programming devices) 
and USB-Serial bridges. A pcmcia serial card with a real UART solved all 
problems.

Maybe you do not have rights to write into the
current directory.

Try

   touch high.txt

to verify.

From an old makefile (mega128) here is the commandline I was using to
read out the fuses:

SERIAL  =3D /dev/ttyUSB0

avrdude -p m128 -b 57600 -c jtagmki -P ${SERIAL} -U hfuse:r:h-
fuse.txt:i -U lfuse:r:l-fuse.txt:i -U efuse:r:e-fuse.txt:i

Perhaps you want to look at Rowley's Linux edition for Atmel micros
since this would take out the guesswork and it's much easier to work
with a real integrated debugger (IMHO). rowley.co.uk - a personal
license will cost you $150.

Also, winavr works perfectly happily inside VirtualBox under Linux, as
does the JTAG-ICEmkii and the STK500.

Quit being puffed up, install Windows, install AvrStudio and enjoy. If 
you are really high and mighty, then don't ask stupid questions.

I cannot read fuses on ATMEGA8515 using STK500 (I have only tested this
so far) in Linux (Kubuntu 8.04) using avrdude 5.5. I have tried
variations of this command such as using sudo, but nothing works.

$ avrdude -c stk500v2 -p m8515 -P /dev/ttyUSB0 -U hfuse:r:high.txt -U
lfuse:r:low.txt

According to
<http://electrons.psychogenic.com/modules/arms/art/14/AVRFusesHOWTOGuide.php>
one should get something similar to:
$ avrdude -c stk500 -p m8 -P /dev/ttyS0 -U hfuse:r:high.txt -U
lfuse:r:low.txt

  avrdude: Device signature = 0x003d04

  avrdude: reading lfuse memory:

  avrdude: writing output file "low.txt"

  avrdude done.  Thank you.

Does any one here know what could be wrong with my system?

I can program the chip with my own programs.
