Hi all. I'm using GNUARM with gcc 4.0.2. I installed YAGARTO with gcc 4.4.1 and I was trying to compile my project with it. My project uses a LPC2292. When I try to compile my project with yagarto I get errors like this: c:/program files/yagarto/bin/../lib/gcc/arm-elf/4.4.1/../../../../arm-elf/bin/ld.ex e: ERROR: c:/program files/yagarto/bin/../lib/gcc/arm-elf/4.4.1\libgcc.a(_udivsi3.o) uses hardware FP, whereas armit_21.o uses software FP c:/program files/yagarto/bin/../lib/gcc/arm-elf/4.4.1/../../../../arm-elf/bin/ld.ex e: failed to merge target specific data of file c:/program files/yagarto/bin/../lib/gcc/arm-elf/4.4.1\libgcc.a(_udivsi3.o) c:/program files/yagarto/bin/../lib/gcc/arm-elf/4.4.1/../../../../arm-elf/bin/ld.ex e: error: no memory region specified for loadable section `.eh_frame' I try to compile my file with option -mhard-float but the result is the same. I also try the options -mfloat-abi=softfp and -msoft-float but the result is the same. Can anyone help with this? I'm around this for a couple of days and I'm stuck. Thanks. Rui
:
- Use the compiler-frontend (arm-elf-gcc) for linking, do not call the linker (arm-elf-ld) directly - Pass the target specific options to the gcc-call for linking as you use for compilation (mcu, thumb, thumb-interwork...) - Show the complete output of "make all" so all options for compiling assembling and linking can be seen. - Show the linker-script - Create a minimal example with all needed files (makefile, sources, linker-script) to reproduce the problem, pack them into a zip-file and attach the zip-file to a forum-message.
The .eh_frame section is a known GCC 4.4.x problem: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40521 You have to discard it by adding something like this to the linker script:
1 | /DISCARD/ : |
2 | {
|
3 | *(.eh_*) |
4 | } |

Thank you very much Giovani.
Your solution works just fine.
I can compiled without any problems and the program runs in my board as
I expected.
I had found the .eh_frame section issue already.
But I had implemented the solution found in the yagarto site:
. = ALIGN(4);
.eh_frame :
{
KEEP (*(.eh_frame))
} > ram
It compiled ok but I couldn't download the program using lpc21isp
(version 1.64).
I got this error:
«New Extended Linear Address Record [04] out of memory range
Current Memory starts at: 0x00000000, new Address is: 0x40000000»
So I remove this section and went back to the linker problem.
Thank you very much once again.
Regards.

Thank you very much Martin. I learn many in the past from your posts. By my reply to Giovani you can see my problem is solved. Nevertheless I would like to give you some feedback on your post. Maybe I'm doing things in the wrong way or they could be done better. Your feedback is appreciated. For compiling I'm using: arm-elf-gcc -I"inc" -I"inc/tcp_ip" -mcpu=arm7tdmi -c -save-temps -fverbose-asm -Wall -Wextra -Wmissing-include-dirs -Wswitch-default -Wfloat-equal -Wundef -Wcast-qual -Wpacked -Wshadow -Wcast-align -Wswitch-enum -Wbad-function-cast -Winit-self -Wpointer-arith -Waggregate-return -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -O3 src/main.c For linking arm-elf-gcc -nostartfiles -Wl,-Map=armit_21.map,--cref,-nostdlib \ -Tlink/lpc2292.ld -s -o armit_21.o asm/crt0.s \ asm/interrupts.s main.o cmd_int.o nv_mem.o app_can.o card.o ... then arm-elf-objdump -x -t --source --full-contents armit_21.o > armit_21.dmp then arm-elf-objcopy --output-target ihex armit_21.o armit_21.hex Regards.
