Hi
I've noticed a problem with strncpy_P where the wrong version of lpm is used.
/snip
1e646: fb 01 movw r30, r22
1e648: dc 01 movw r26, r24
0001e64a <.strncpy_P_loop>:
1e64a: 41 50 subi r20, 0x01 ; 1
1e64c: 50 40 sbci r21, 0x00 ; 0
1e64e: 48 f0 brcs .+18 ; 0x1e662
1e650: 05 90 lpm r0, Z+ <<<<
should be elpm r0, Z+ on mega 128 ?
1e652: 0d 92 st X+, r0
1e654: 00 20 and r0, r0
1e656: c9 f7 brne .-14 ; 0x1e64a
1e658: 01 c0 rjmp .+2 ; 0x1e65c
It looks like macros.inc is expecting __AVR_ENHANCED__ to be defined somwhere.
i'm using avr-gcc v3.3.2, wonder if this a a fault with my installation.
Cheers
Simon
