FYI: I currently have QEMU-based ARM platform I use for testing other s/w: + a single-cpu ARMv5 system running Debian Squeeze + a dual-core ARMv7 system running Ubuntu Precise
Since these are EMULATED platforms, they are a bit on the slow side, making periodic MTT runs untenable. However, I am willing/able to run on-demand tests of release candidates if Leif is not already performing such testing. -Paul On Fri, Jan 25, 2013 at 4:05 PM, Jeff Squyres (jsquyres) <jsquy...@cisco.com > wrote: > On Jan 25, 2013, at 7:28 AM, Leif Lindholm <leif.lindh...@arm.com> wrote: > > >> Mmm.
