Problems during setup Mali Graphics Debugger on Android 4.1

guozhu

System Info

graphics: Mali-400MP, android version: 4.1.1, Mali Graphics Debugger: 2.0

when I try to setup the Mali Graphics Debugger  on android device following the user guide.

the libGLES_mgd say it can't load the libGLES_mali.so (because this library isn't here, but libEGL_mali.so and the other two).

files in /system/lib/egl/ :

shell@android:/system/lib/egl # ls

egl.cfg

libEGL_mali.so

libGLES_android.so

libGLES_mgd.so

libGLESv1_CM_mali.so

libGLESv2_mali.so

but the mgd only try to load libGLES_mali.so (/vendor/lib/egl/ have been mapped to /system/lib/egl/):

I/libGLES_mgd(30489): libGLES_mgd is in a system folder

E/libGLES_mgd(30489): Failed to parse process mappings.

D/libEGL  (30489): loaded /vendor/lib/egl/libGLES_mgd.so

any suggestion is appreciated

    Hi guozhu

    In this instance, it looks like the BSP on the device is built non-monolithic. As such, the actual driver is likely to be found here: /system/lib/libMali.so

    MGD isnt looking there however, so you could, as pete suggested, make a symlink for MGD to correctly redirect

    ln -s /system/lib/libMali.so /vendor/lib/egl/libGLES_mali.so

    Hope it helps, I have raised this the the tools team, to see if this is expected behaviour.

    Kind Regards,
