I'm using the 20-bit development version of mspgcc and am blocked by a
linker error: "dangerous relocation: unaligned address":
make test.elf
msp430-gcc -I/usr/local/msp430/include -std=c99 -Wall -Os -g
-mmcu=msp430f5528 -mmemory-model=large -ffunction-sections -fdata-sections
-Ibuild -c file.c -o build/obj/file.o
msp430-gcc -mmcu=msp430f5528 -mmemory-model=large -Wl,-gc-sections <… many
.o files…> -o build/test.elf
build/obj/file.o: In function `sm_packet_handler':
/Users/andy/code/.../file.c:1569:(.any.text.sm_packet_handler+0x4ac):
dangerous relocation: unaligned address
collect2: error: ld returned 1 exit status
make: *** [test.elf] Error 1
I have no clue as to what's going on, or what I can do to fix it. The
function that appears to be generating the error is fairly large with a
number of nested switch statements. But I'm not sure if sm_packet_handler
is at fault, or whether a symbol it references is causing the problem.
One thing I noticed in dumping the .o file is that sm_packet_handler is
using two different ".rodata" sections:
$ msp430-objdump -h build/obj/file.o | grep sm_packet_handler
17 .any.rodata.sm_packet_handler 00000011 00000000 00000000 0000096c
2**0
18 .any.text.sm_packet_handler 00000d94 00000000 00000000 0000097e 2**1
19 .rodata.sm_packet_handler 00000154 00000000 00000000 00001714 2**2
Is that relevant at all? Has anyone else run into this error message?
