This is where you go wrong :) GLX is for OpenGL, and on ARM devices it's typically OpenGL ES instead. When running glxgears, you're in fact using the software rendering for GL. I'd try to use http://www.daimi.au.dk/~cvm/glestest.cc if I were you instead - http://www.daimi.au.dk/~cvm/glestest is a armv7l binary, chmod +x it and ./glestest I'm a little unsure if the EGL/GLESv2 -> GLX -> swrast works properly in Mesa, which may be why it's crashing. I know that Sage's XBMC is built for EGL/GLESv2 for sure. We have some work ongoing to support Mesa with LLVMpipe, which is a kind of fast software rendered EGL/GLESv2, utilizing the CPU instead of a GPU, but the LLVM JIT has problems on ARM chips currently, while it works fine on X86. XBMC would also require EGL/GLESv2 support and is very slow with software rendering, an actual chip is recommended for that - it was even slow on my 2.3ghz X86 with swrast. > > (9) Execute the following commands: > #Xorg & > #export DISPLAY=":0.0" > #glxgears > glxgears can work fine! > > (10) #xbmc & > XBMC cannot work with following error: > /usr/bin/xbmc: line 133: 1064 Illegal instruction > "$LIBDIR/xbmc/xbmc.bin" $SAVED_ARGS > Crash report available at /root/xbmc_crashlog-19691231_161444.log (See > attachment) > In the crashlog, We can confirm that XBMC have used Mesa 3D drivers, Not pvr > 3D drivers. What's wrong then?? I'd like to see /proc/cpuinfo since this is a new chipset we haven't tested Mer on (we've tested on Tegra2, OMAP3/4, Marvell, ST-Ericsson, Freescale, etc, but not this one). > > Any help or instruction is appreciated! > Thanks in advance!
