Details:
In the iom88.h and the iom168.h the extended fuse bytes are incorrect. The
fuse bytes defined are from the atmega48 (witch is in the same datasheet).
The current code:
/* Extended Fuse Byte */
#define SELFPRGEN ~_BV(0) /* Self Programming Enable */
#define EFUSE_DEFAULT (0xFF)
and should be:
/* Extended Fuse Byte */
#define BOOTSZ1 ~_BV(2) /* Select boot size */
#define BOOTSZ0 ~_BV(1) /* Select boot size */
#define BOOTRST ~_BV(0) /* Select reset vector */
#define EFUSE_DEFAULT (0xF9)
Hope it's fixed in the next release (I didn't check the other header files)
