I didn't see any. I believe we do not currently have proper support for flat binaries. You should have a look at: scripts/build/kernel/linux.sh in function CT_DoKernelTupleValues: CT_DoKernelTupleValues() { if [ "${CT_ARCH_USE_MMU}" = "y" ]; then CT_TARGET_KERNEL="linux" else # Sometime, noMMU linux targets have a -uclinux tuple, while # sometime it's -linux. We currently have only one noMMU linux # target, and it uses -linux, so let's just use that. Time # to fix that later... # CT_TARGET_KERNEL="uclinux" CT_TARGET_KERNEL="linux" fi } So in your case, I guess you'd want a tuple that ends with -uclinux instead of -linux. Care to test that (override in the script)? If it works, then it will be time to review that function and be a bit more inventive there. Also, in the binutils sub-menu, you will have to choose one of: - 'Flat' and a version of elf2flt, - 'FD_PIC ELF' Note: AFAICR, the "only one noMMU linux target" referred-to in the linux kernel script, above, is blackfin.
