Hi, a few notes:

Hmm... It seems that the SDK's QEMU does not > emulate a ARMv6 device? - yes. See http://developer.android.com/tools/devices/emulator.html. Btw, there is not much point to compiling for armv6 for Android. The two official ABIs are either armv5te + softfloat or armv7a + vfpv3_d16 (maybe v2). - there were lots of fixes to ARM interlocked* stuff and barriers some months ago in trunk. All these changes are not in the targetandroid branch. - the (trunk) rtl still has some issues related to automatic detection and use of read/writebarrier code if you compile for an older cpu but run on newer. E.g. if you compile for armv5, these barriers are nops because they are not needed - but when actually running on something higher these nops are not optimal to say at least. If your stuff is not threaded or you don't run on a multi-core cpu, this is not a problem. - if you are really interested about doing Android development, I recommend getting a developer board. The emulator is really slow. Even fast developer boards are really cheap now, e.g. quad-core 1.4Ghz ARMv7 with 1GB RAM for 70 USD (www.hardkernel.com , search for Odroid-U). This device is actually pretty decent. Otherwise use an unused phone.
