This is the second time I lost contact with this controller. And it is not the same desing.
Latest working fuses is: 0xF9DF62 - Built in RC, 8 MHz
Changed to 0xF995E2 - That is preserve EEPROM, BOD level 2.7V, Enable Debug Wire. My power supply is 5.2 V!
The program will start at power on but I can no longer get any access through SPI.
I suspect that there might be a bug in this controller that disable the SPI if you enable Debug Wire.
