'slink /init /bin/busybox 777 0 0' should be inserted in initramfs
config

I need more information, including full kmsg and initramfs configs
My qemu commands as following. Maybe useful.
qemu-new:
@test -d $(DIR_WORKING)/qemu-unicore32 || \
mkdir -p $(DIR_WORKING)/qemu-unicore32
@echo "Remove old qemu repo ..."
@rm -fr $(DIR_WORKING)/qemu
@cd $(DIR_WORKING); git clone $(QEMU_GITREPO)
@cd $(DIR_WORKING)/qemu; \
git br unicore32 origin/unicore32; \
git co unicore32
qemu-make:
@echo "Configure qemu ..."
@cd $(DIR_WORKING)/qemu; ./configure \
--enable-trace-backend=stderr \
--target-list=$(QEMU_TARGETS) \
--enable-debug \
--disable-sdl \
--interp-prefix=$(DIR_GNU_UC) \
--prefix=$(DIR_WORKING)/qemu-unicore32 \

@make -C $(DIR_WORKING)/qemu -j4 >> $(QEMU_BUILDLOG) 2>&1
@make -C $(DIR_WORKING)/qemu install >> $(QEMU_BUILDLOG) 2>&1
qemu-run:
@echo "Remove old log file"
@rm -fr $(QEMU_TRACELOG)
