Branch: poky/master Git rev: 0bedc0b80d9b46cbbf4a2c5e120a6aa52cbc7c2e Steps: 1. Build qemuarm or qemuppc poky-tiny image 2. Run command "runqemu qemuarm ramfs" or "runqemu qemuppc ramfs" to boot up the image. I also tried qemux86, qemux86-64 and qemumips, they can boot up without problem.

ppc and arm are currently not really tested with tiny. Note that linux-yocto-tiny COMPATIBLE_MACHINE only lists qemux86. We need to support the others, but that is an enhancement to what exists currently. I suggest Scott verify runqemu does what it is supposed to here and that the failure is that the kernel in use is linux-yocto (and not linux-yocto-tiny). Another bug should be opened to add supported to tiny for the other archs.
what's poky tiny?
I have been unable to reproduce this as I get an even more basic failure in runqemu. Will continue debugging next week.
Jackie does this work for you now on 2.0?
(In reply to comment #4) > Jackie does this work for you now on 2.0? No, for now, linux-yocto-tiny COMPATIBLE_MACHINE only lists qemux86, qemuarm and qemuppc can't even be built.
linux-yocto-tiny only works with qemux86 now: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/meta/recipes-kernel/linux?id=3ad70a599f78f645dc212ef7f5fa49ccce3ef1f7
linux-yocto-tiny is limited to only qemux86 now.
