I have a driver loadable module which i am compiling with the same gcc flags as used to compile a kernel for a MIPS R5432 based NEC board. On the development machine, to compile files driver1.c and driver2.c: $ mips_fp_le-gcc -fomit-frame-pointer -fno-strict-aliasing -G 0 -mno-abicalls -fno-pic -pipe -mtune=r5000 -mlong-calls -mips2 -Wall -c driver1.c $mips_fp_le-ld -r -o driver --printmap --cref driver1.o driver2.o mips_fp_le-gcc (GCC) version 3.3.1 mips_fp_le-ld (GNU ld) version 2.14 I have Busybox v0.60.2 on the target. On the target: # insmod ./driver Using driver Segmentation fault # Does anybody have any suggestions as to what could be wrong? Thanks in advance, Manu
