I have the signature 'code' in assembly[1], but I'm not sure how to link it so that it ends up as the first bit of code in the ELF image (the very first instruction is a 'b' to jump over the actual signature text.)Without this the boot monitor will refuse to boot the kernel. Any suggestions as to how I might accomplish this? Edit the linker script (arch/mips/kernel/vmlinux.lds.S) David Daney |
