how did you compile it. did you use the same flags as were used in linux ?
or32-uclinux-gcc -D__KERNEL__
-I/center/opencores/toolchains/oc-2.31/p_root/linux-2.4/include -Wall -Wstr
ict-prototypes -Werror-implicit-function-declaration -fno-strict-aliasing -O
-nostdlib -fomit-frame-point
er -I/center/opencores/toolchains/oc-2.31/p_root/linux-2.4/arch/or32
-fsigned-char -msoft-float -pipe -ff
ixed-r2 -Wno-uninitialized -D__linux__ -nostdinc -iwithprefix include
-DKBUILD_BASENAME=serial -DEXPORT
_SYMTAB -c serial.c
for example if i compile it without any flags it works:
dua:/__test# cp serial.E serial.c
dua:/__test# or32-uclinux-gcc -c serial.c
serial.c: In function rs_ioctl':
serial.c:2646: warning: passing arg 1 of signal_pending' discards qualifiers
from pointer target type
serial.c: In function rs_wait_until_sent':
serial.c:2921: warning: passing arg 1 of signal_pending' discards qualifiers
from pointer target type
serial.c: In function block_til_ready':
serial.c:2963: warning: initialization discards qualifiers from pointer

serial.c:3070: warning: passing arg 1 of signal_pending' discards qualifiers

dua:/__test# ll

drwxr-xr-x 2 root root 120 Jan 27 13:57 ./
drwxr-xr-x 36 root root 2216 Jan 27 13:56 ../
-rw-r--r-- 1 root root 391140 Jan 27 13:56 serial.E
-rw-r--r-- 1 root root 391140 Jan 27 13:57 serial.c
-rw-r--r-- 1 root root 65536 Jan 27 13:57 serial.o
but adding just -O makes it crash
dua:/__test# rm serial.o
dua:/__test# or32-uclinux-gcc -O -c serial.c
