I had some time today and built a bootloader shield. To test it I take a brand new 1284P and burn a bootloader on it. This is the log:
Atmega chip programmer.
Written by Nick Gammon.
Entered programming mode OK.
Signature = 0x1E 0x97 0x05
Processor = ATmega1284P
Flash memory size = 131072 bytes.
LFuse = 0x62
HFuse = 0x99
EFuse = 0xFF
Lock byte = 0xFF
Clock calibration = 0x8D
Bootloader address = 0x1FC00
Bootloader length = 508 bytes.
Type 'V' to verify, or 'G' to program the chip with the bootloader ...

Written.
Verifying ...
No errors found.
Writing fuses ...
LFuse = 0xFF
HFuse = 0xDE
EFuse = 0xFD
Lock byte = 0xEF
Clock calibration = 0x8D
Done.
Type 'C' when ready to continue with another chip ...
I will post a log with the fuses of the other chip which I am trying to programm later.
By the way this is my bootloader shield: View Image (3,3MB)
I show this because I haven't seen anything similar.
EDIT:
This is the log of the µC we are talking about. Again, thanks for your help.
