Understood. I there a better emulation to try? When you say "this hardware" do you mean the board, or do you mean big endian arm as a CPU? Because there _is_ a qemu-armeb. There isn't a qemu-system- armeb that I'm aware of, but I thought it autodetected endianness at least for the CPU...) If it's the board, I did that because versatilepb has essentially been the generic board emulation I've plugged all the other arm variants into. There isn't a -M ip4xx that I'm aware of. (I can try configuring a kernel with just serial console and see if I can get that to boot, and then add back net and disk and such one at a time, if that might be a reasonable approach...) > > Does this look more like a kernel error, or a qemu error? > > Probably both. If I could just get them to agree, I'd be happy. I just want a setup that can run a big endian arm userspace under system emulation (with network, serial console, clock, and disk). Emulating a feasible board would be a nice bonus, but not actually a goal. > Paul Rob -- Latency is more important than throughput. It's that simple. - Linus Torvalds
