1st thing you need to up/download memory (from debug) to have the EEP
file put into eeprom space.
Then the first time around you are filling r16 with 0 and then
decrementing it which points to 0xff. Last EEPROM address is 0x7f
or 128 bytes :)

This is my EEP reading routine, try to find out why yours doesn't
work :)

;Get 1 byte pointed by Z. Data returned in temp
get_ieep_byte:
     out    EEARL,zl   ;Sets up address in EEP
     sbi   EECR,EERE
     in    temp,EEDR   ;Get data
     ret

EEARH also is not used as it is only needed when EEP>256 bytes.
Once I made some small changes to your code I could see the EEP
data into r0.
