[avr-chat] avrdude-ATMega32 fuse bits issues

[Chris Pontiga]

Hello,

I am having quite a bit of trouble with the fuse bits and I have 4
chips which exhibit this issue.  I am able to program the chip
with the default factory settings and it functions fine.  However,
I need to use a 16Mhz external crystal.  So I have that hooked up
between the two XTAL pins with two 22pF caps to gnd.  

I use the following to program the fuses:

fuse:
    avrdude -u -pm32 -cbsd -E noreset -U lfuse:w:0x5f:m
    avrdude -u -pm32 -cbsd -E noreset -U hfuse:w:0xd1:m

programming the fuses fails with the following:
[code]
C:\Documents and Settings\Chrispy\Desktop\a>make fuse
avrdude -u -pm32 -cbsd -E noreset -U lfuse:w:0x5f:m

I do not know why programming the fuses would make the chip completely
non-functional.  I did not program the lock bits either so this is
very puzzling.  Any attempt to program the chip results in a
similar verification error with first mismatch at 0x000.

I would appreciate anyone's help.  I have 4 chips with this issue.  

Thanks in advance,
Chris
