Added __used__ in <avr\signature.h> and avr-objdump -s -j .signature
is working again:
const unsigned char __signature[3] __attribute__((__used__))
__attribute__((section (".signature"))) =
{ SIGNATURE_2, SIGNATURE_1, SIGNATURE_0 };
Need same change in <avr\lock.h> and <avr\fuse.h>:
#define LOCKMEM __attribute__((__used__)) __attribute__((section (".lock")))
#if !defined(FUSES)
#if defined(__AVR_XMEGA__)
#define FUSES NVM_FUSES_t __fuse FUSEMEM __attribute__((__used__))
#else
#define FUSES __fuse_t __fuse FUSEMEM __attribute__((__used__))
#endif
#endif
