Just to get registered. I edit the uClinux-dist/Makefile and comment the
line on target modules_install that strip the modules and it's shown below:

modules_install:
        . $(LINUXDIR)/.config; if [ "$$CONFIG_MODULES" = "y" ]; then \
                [ -d $(ROMFSDIR)/lib/modules ] || mkdir -p
$(ROMFSDIR)/lib/modules; \
                $(MAKEARCH_KERNEL) -C $(LINUXDIR)
INSTALL_MOD_PATH=$(ROMFSDIR) DEPMOD="../user/busybox/examples/depmod.pl -k
vmlinux" modules_install; \
                rm -f $(ROMFSDIR)/lib/modules/*/build; \
                rm -f $(ROMFSDIR)/lib/modules/*/source; \
#               find $(ROMFSDIR)/lib/modules -type f -name "*o" | xargs -r
$(STRIP) -R .comment -R .note -g --strip-unneeded; \
        fi


I'd like to thank you all that help me in this problem. Thanks for all the
answers and all the best to you and to your families ! ;)


Best Regards, Josue.
