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.

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. 53756 2 benjamin.esquivel 2015-09-04 20:38:31 +0000 what's poky tiny? 53765 3 benjamin.esquivel 2015-09-04 22:59:32 +0000 I have been unable to reproduce this as I get an even more basic failure in runqemu. Will continue debugging next week. 56497 4 randy.macleod 2015-11-16 16:26:53 +0000 Jackie does this work for you now on 2.0? 65907 5 jackie.huang 2016-09-08 07:38:50 +0000 (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. 68059 6 jackie.huang 2016-11-08 01:30:03 +0000 linux-yocto-tiny only works with qemux86 now: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/meta/recipes-kernel/linux?id=3ad70a599f78f645dc212ef7f5fa49ccce3ef1f7 68060 7 jackie.huang 2016-11-08 02:17:51 +0000 linux-yocto-tiny is limited to only qemux86 now.
