Description Yi Zhao 2013-03-06 07:53:27 UTC

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.

Comment 1 Darren Hart 2013-03-07 15:44:16 UTC

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.

Comment 2 Benjamin Esquivel 2015-09-04 20:38:31 UTC

what's poky tiny?

Comment 3 Benjamin Esquivel 2015-09-04 22:59:32 UTC

I have been unable to reproduce this as I get an even more basic failure in runqemu.

Will continue debugging next week.

Comment 4 Randy MacLeod 2015-11-16 16:26:53 UTC

Jackie does this work for you now on 2.0?

Comment 5 Jackie Huang 2016-09-08 07:38:50 UTC

> 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.

Comment 6 Jackie Huang 2016-11-08 01:30:03 UTC

linux-yocto-tiny only works with qemux86 now:
http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/meta/recipes-kernel/linux?id=3ad70a599f78f645dc212ef7f5fa49ccce3ef1f7

Comment 7 Jackie Huang 2016-11-08 02:17:51 UTC

linux-yocto-tiny is limited to only qemux86 now.
