Hi List, after a sleepness nigth I got an idea .... Because I need an uImage I had to build a Image first. The buildprocess of the kernel call this wrong line mips_4KCle-objcopy --remove-section=.reginfo vmlinux arch/mips/boot/Image if I add this rule in the Makefile $(obj)/Image: $(VMLINUX) FORCE $(call if_changed,objcopy) @echo ' Kernel: $@ is ready' On older kernelversions this works well! The rigth one is this: mips_4KCle-objcopy -O binary -R .note -R .comment -S vmlinux arch/mips/boot/Image I typed the last steps by hand for now and it works gzip -f -9 < arch/mips/boot/Image > arch/mips/boot/zImage /bin/sh /tmp/linux-2.6.28.1/scripts/mkuboot.sh -A mips -O linux -T kernel -C gzip -a 0x80100000 -e 0x80104690 -n 'Linux-2.6.28.1' -d arch/mips/boot/zImage uImage (keep in mind the -a 0x80100000 -e 0x80104690 parameters are greped from vmlinux with TEXT_ADDR := $(shell awk '/_text/ { printf "0x%s", $$1 ; exit }' < $(TOPDIR)/System.map) ENTRY_ADDR := $(shell awk '/kernel_entry/ { printf "0x%s", $$1 ; exit }' < $(TOPDIR)/System.map) ) Than I can see my first early printk messages :-) huhuuu Now I can work on. BTW: why is uImage not supported by the kernel build system for MIPS? Regards, Frank
