Thanks to all,
My current fuse setting is as below:
$ uisp -dprog=mib510 -dserial=/dev/ttyS0 --rd_fuses -dpart=ATmega128
Firmware Version: 2.1
Atmel AVR ATmega128 is found.
Fuse Low Byte = 0xff
Fuse High Byte = 0xd8
Fuse Extended Byte = 0xff
Calibration Byte = 0x00 -- Read Only
Lock Bits = 0xff
BLB12 -> 1
BLB11 -> 1
BLB02 -> 1
BLB01 -> 1
LB2 -> 1
LB1 -> 1
If I want to enable BODEN, is that I should change Fuse Low Byte from 0xff
to 0xbf?
Thanks a lot for the help
Tony
