Yep, a bug in TortoiseGIT that was later fixed. > Ok, dug it up, applied it, booted an -M versatilepb kernel built with an > armv4tl compiler that I'm assured works for real armv4tl hardware, and I get > no boot messages if I say "-cpu arm7tdmi", but it boots fine if I don't say > that. > > Let's try my armv4l setup (which I've booted on real armv4tl hardware, albeit > with a different kernel .config but qemu hasn't got a board emulation for the > Tin Can Tools Hammer, last I checked...)
