This makes a lot of sense, only that I do not observe the string actually being copied to RAM: char test1[] = "abd"; if (test1[0] == 'a') DO_SOMETHING; DO_SOMETHING doesn't happen. I see that the produced assembly char test1[] = "abd"; lds r24, 0x0100 lds r25, 0x0101 lds r26, 0x0102 lds r27, 0x0103 std Y+15, r24 ; 0x0f std Y+16, r25 ; 0x10 std Y+17, r26 ; 0x11 std Y+18, r27 ; 0x12 loads bytes from SRAM, which should be abc\0 for the string to get initialized in data segment, but I'm getting 0xff at runtime. Please advise. Zoran _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
