Hi,
to program the flash I use the JTAG interface over a serial port.
I would set the fuse bytes to
lfuse 0x3F
hfuse 0x90
efuse 0xFF
by using stk500 and following command:
stk500 -dATmega128 -f903F -EFF
Verifying with command
stk500 -dATmega128 -F903F -GFF
shows following:
STK500 command line programmer, v 2.2 Atmel Corp (C) 2004-2005.
Scanning ports:
COM1 ... Port busy or STK500 not connected
COM2 ... Connected to STK500 V2 on port COM2
Device parameters loaded
Could not enter programming mode
Programming mode left
Connection to STK500 V2 closed
WARNING! One or more operations failed! Please examine the output
log above!
I have tried to set the fuse bytes also with another programmer avrdude
by using following command:
avrdude -p m128 -c stk500v2 -P COM2 -U hfuse:w:0x90:m

avrdude: safemode: hfuse changed! Was 90, and is now 8
Would you like this fuse to be changed back? [y/n] n
avrdude: safemode: Fuses OK
avrdude done. Thank you.
Here a timeout error is shown. Now the fuse bits have following values:
lfuse 0
hfuse 8
efuse 8
To get this I have entered following:
avrdude -p m128 -c stk500v2 -P COM2 -t -v
avrdude: Version 5.0

What can I do?
I don't know a way out.
