Dear Sebastian Huber, Jonathan Brandmeyer and RTEMS community, Thank you for your valuable inputs and suggestions to my problem with big-endian targets. I was able to resolve most of the issue by adding the CPU_FLAGS to linker as well.
Now I have a few new errors; *‘**compiled for a little endian system and target is big endian**’* which are just opposite of the previous ones. The following are my console outputs: /../../../../arm-rtems4.11/bin/ld: /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_aeabi_uldivmod.o): compiled for a little endian system and target is big endian /../../../../arm-rtems4.11/bin/ld: failed to merge target specific data of file /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_aeabi_uldivmod.o) /../../../../arm-rtems4.11/bin/ld: /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(bpabi.o): compiled for a little endian system and target is big endian /../../../../arm-rtems4.11/bin/ld: failed to merge target specific data of file /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(bpabi.o) /../../../../arm-rtems4.11/bin/ld: /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_dvmd_tls.o): compiled for a little endian system and target is big endian /../../../../arm-rtems4.11/bin/ld: failed to merge target specific data of file /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_dvmd_tls.o) /../../../../arm-rtems4.11/bin/ld: /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_divdi3.o): compiled for a little endian system and target is big endian /../../../../arm-rtems4.11/bin/ld: failed to merge target specific data of file /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_divdi3.o) /../../../../arm-rtems4.11/bin/ld: /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_udivdi3.o): compiled for a little endian system and target is big endian /../../../../arm-rtems4.11/bin/ld: failed to merge target specific data of file /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_udivdi3.o) /../../../../arm-rtems4.11/bin/ld: /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_clzdi2.o): compiled for a little endian system and target is big endian /../../../../arm-rtems4.11/bin/ld: failed to merge target specific data of file /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_clzdi2.o) /../../../../arm-rtems4.11/bin/ld: /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_clzsi2.o): compiled for a little endian system and target is big endian /../../../../arm-rtems4.11/bin/ld: failed to merge target specific data of file /opt/rtems/4.11/bin/../lib/gcc/arm-rtems4.11/4.9.3/libgcc.a(_clzsi2.o) *I have only used the RSB from RTEMS **to make the toolchain and all GCC files are from RTEMS only.* Can you help me resolve this issue? All similar issues I found on internet are related to GNU GCC compilers. That is why I am looking for a solution from here. Thank you very much for your time and effort.
