I have been debugging with this kind of setup over the past few days. I don't think you can just load your image like you are doing: it is loading at 0xc... which is a virtual address and the MMU hasn't been setup yet. Instead try doing your steps 1-6 but instead of "load" do: hbreak start_kernel cont then in u-boot boot the kernel from uImage over TFTP or from flash. Your debugger will break near the start of kernel execution and you can debug from there using software breakpoints (MMU will be on). If you need to debug the early stuff before MMU is on try hbreak 0x80008000 instead of start_kernel and have a look at arm-none-linux-gnueabi objdump -S arch/arm/boot/compressed/head.o -- Jon Povey jon.po...@racelogic.co.uk Racelogic is a limited company registered in England.
