Hi:
Our Configuration:-
Architecture - arm920 ( arm v4 ) + without FPU unit
Toolchain - gcc-4.1.1 + eabi
Kernel - linux 2.6.18.2 + NWFPE emulator
Problem :-
After i applied my patch to eabi toolchain to work for v4
architecture, my kernel boots up and i get a fine shell prompt.
However, my LKM gives me following error :-
Unknown symbol __aeabi_uldivmod
Ok, at ..
1) Some uclibc options ,
UCLIBC_HAS_FPU = y
Kernel NWFPE is selected
Other symbols that are present in my module and not giving unknown
sumbols are, for example __eabi_idiv, etc...
2)
toolchain_build_arm_nofpu/gcc-4.1.1/gcc/config/arm/t-bpabi -->
LIB1ASMFUNCS has __aeabi_uldivmod and LIB2FUNCS_EXTRA includes bpabi.c
3)
also in,
toolchain_build_arm_nofpu/gcc-4.1.1-final/gcc/libgcc.a --> when i
take the objdump, it shows the pirticular function __aeabi_uldivmod
TIA,
Naval
