3) Working FUSE for M1284 (with bootloader Zevero-SD)
I.e - Arduino Bootloader to Flash from SD Card: https://github.com/zevero/avr_boot

PS. SET FUSES:
==============
  LOW = 0xFF
  HIGH = 0xDA
  EXTD = 0xFD
========================================
It means:
Ext. XTAL High FREQ START-UP 16K CK + 65ms
JTAG DISABLED
BROWN-OUT 2.7V ON
BOOT-LOADER ENABLED
BOOT Flash Section Size = 2048 words; Boot Start address = 0xF800
=========================================

AVRDUDE arguments:
-U lfuse:w:0xff:m -U hfuse:w:0xda:m -U efuse:w:0xfd:m

Full commands to write from console:
avrdude -Pusb -cavrispmkii -patmega1284p -B5 -U lfuse:w:0xff:m -U hfuse:w:0xda:m -U efuse:w:0xfd:m


Detection avrdude CPU: B5 (5us bit clock period for programmer SPI) - VERY IMPORTANT (1Mhz CPU M1284p FREQ DEFAULT)
