Hi,
①I am using Devkit8500( timll company in shenzhen, guangdong, china) now,
I met with some problems when I wanted to run the examples in beagleboar
②I cut the following massage that print when booting:

③AND the following word is my loadmodeluse.sh

④I get the following message when I executed my loadmodules.sh
CMEM Range Overlaps Kernel Physical - allowing overlap
CMEM phys_start (0x86300000) overlaps kernel (0x80000000 -> 0x8e300000)

⑤But the example in codec engine can‘t working。

app: error: can't open engine image_copy
@0x000def75:[T:0x4001e320] ti.sdo.ce.examples.apps.image_copy - app done.
What should I do in order to solve this problems.
thank you
