Thanks for your help,
The link you have sent to me, http://www.ethernut.de/en/isp/fuses.html, say
that the correct fuses setting are as following:
Ethernut Factory Settings
We can call uisp on the command line to read the fuses. Again the following
parameters are for the SP Duo connected to the first serial port.
# uisp -dprog=stk500 -dserial=/dev/ttyS0 -dspeed=115200 -dpart=atmega128
Firmware Version: 49.48
Atmel AVR ATmega128 is found.
Fuse Low Byte = 0x3f
Fuse High Byte = 0x83
Fuse Extended Byte = 0xff
Calibration Byte = 0x00 -- Read Only
Lock Bits = 0xff
BLB12 -> 1
BLB11 -> 1
BLB02 -> 1
BLB01 -> 1
LB2 -> 1
LB1 -> 1
which mean that my fuses are correct and for hfuse I but it 0x82 for the
bootloader, this is also mentioned in the above link,
I also try to make it 0x83 but nothing happened, also the atmega 103
compatibility is disabled, I'm sure , and you can check it by your self.
I don't know, do you have another suggestions.
