Yes, you missed the section "More About U-Boot Image Types" in the README which explains what "Multi-File Images" are and how they can be used to do exactly what you are looking for, and you also missed to read the FAQ section in the DULG, especially http://www.denx.de/twiki/bin/view/DULG/CombiningKernelAndRamdisk > As I understand it, the mkimage utility that comes with the PPCBoot/Das > U-Boot bootloader software can build a combined image containing both > the kernel and the file system - following is from the PPCBoot documentation: > > -> tools/mkimage -n '2.2.13 for initrd on TQM850L' \ > > -A ppc -O linux -T kernel -C gzip -a 00000000 -e 0000000C \ > > -d /opt/mpc8xx/src/linux-2.2.13/arch/ppc/coffboot/vmlinux.gz \ > > examples/image-2.2.13-initrd Well, "-T kernel" requests for a "kernel type" image. If you want something else, use a different option (like -T multi" for multifile images. See mkimage's useage message. > My confusion arises from the fact that I don't see a way of > specifying the address to which the file system will be downloaded, You don;t have to care.

With a multifile image, ther eis only one image and thus only one address argument for 'bootm'. > I'd be grateful for any help received. Chances for help would be better if you didn't post to mailing list where your question is off topic - this has actually nothing to do with linuxppc-embedded; you should have posted to u-boot-users instead.
