This doesn't show if it is stripped. try list the size of your module in
the kernel tree and on the target.
The module is build with those commands:
mb-gcc -D__KERNEL__ -I/root/uClinux/cvs/uClinux-2.4.x/include -Wall
-Wstrict-prototypes -Wno-trigraphs -O1 -g -fno-strict-aliasing
-fno-common
-fno-builtin-sprintf -DPLATFORM=uclinux-auto -O2 -fno-builtin -DNO_MM
-DNO_FPU -D__ELF__ -DMAGIC_ROM_PTR -D__linux__
-I/root/uClinux/microblaze-elf-tools/bin/../lib/gcc/microblaze/3.4.1/./include
-mxl-soft-div -mno-xl-soft-mul -mxl-pattern-compare -DMODULE -nostdinc
-iwithprefix include -DKBUILD_BASENAME=main -c -o main.o main.c
mb-gcc -D__KERNEL__ -I/root/uClinux/cvs/uClinux-2.4.x/include -Wall
-Wstrict-prototypes -Wno-trigraphs -O1 -g -fno-strict-aliasing
-fno-common
-fno-builtin-sprintf -DPLATFORM=uclinux-auto -O2 -fno-builtin -DNO_MM
-DNO_FPU -D__ELF__ -DMAGIC_ROM_PTR -D__linux__
-I/root/uClinux/microblaze-elf-tools/bin/../lib/gcc/microblaze/3.4.1/./include
-mxl-soft-div -mno-xl-soft-mul -mxl-pattern-compare -DMODULE -nostdinc
-iwithprefix include -DKBUILD_BASENAME=access -c -o access.o access.c
mb-gcc -D__KERNEL__ -I/root/uClinux/cvs/uClinux-2.4.x/include -Wall
-Wstrict-prototypes -Wno-trigraphs -O1 -g -fno-strict-aliasing
-fno-common
-fno-builtin-sprintf -DPLATFORM=uclinux-auto -O2 -fno-builtin -DNO_MM
-DNO_FPU -D__ELF__ -DMAGIC_ROM_PTR -D__linux__
-I/root/uClinux/microblaze-elf-tools/bin/../lib/gcc/microblaze/3.4.1/./include
-mxl-soft-div -mno-xl-soft-mul -mxl-pattern-compare -DMODULE -nostdinc
-iwithprefix include -DKBUILD_BASENAME=pipe -c -o pipe.o pipe.c
mb-ld -r -o scull.o main.o access.o pipe.o
on the target board I have:
# ls -l
-rw-r--r-- 1 root 0 19988 Jan 1 00:00 scull.o
and on my computer I have:
Gmicro3-278:~/uClinux/cvs/uClinux-dist/linux-2.4.x/drivers/char/scull#
ls -l
scull.o
-rw-r--r-- 1 root root 335835 2007-10-11 11:07 scull.o
The different size mean that... ?
I believe It is stripped. Then ftp the one in the kernel tree to your
target and test your module.
BTW. what do you have in /proc/sys/kernel/printk ?
I do and "echo 8 > /proc/sys/kernel/printk"... Also don't work.
The value below is fine. If you want to change the value do this
echo "7 4 1 7" > /proc/sys/kernel/printk
By default I have:
# cat /proc/sys/kernel/printk
15 4 1 7
Thanks again David.
Regards, Josue.
