how to test Codec Engine examples in dm8148

I am testing syslink related example, SysLink examples and Codec Engine examples

I have two problem :

1. the "DM814x_EZ_Software_Developers_Guide" said that "The Codec Engine examples cannot be run out with graphics"

   so, require teardown the graphics plane(maybe it use syslink)  to run codecs engine is too far to use!!!!!

does the DSP based application and graphics  based application can not run at the same time?

2. when I teardown the graphics plane(/etc/init.d/load-hd-firmware.sh stop), system crush.

  AM i supported to change init script to not load graphics plane during startup?

  p.s.: bootargs is changed from the default values to MEM=169M

    Hi Ethan,

    For #1, my understanding is that the graphics software stack uses a different memory map when compared with the SysLink and Codec Engine examples in the EZSDK. Hence running them together will result in conflicts.

    I will let someone on the SDK team answer #2, as they are more familiar with the graphics stack and can better tell why the teardown crashed. But I think if you change the init script to ensure it does not run the 3 scripts specified to be stopped in the software developers' guide you should be able to ensure there are no conflicts in the system when running the SysLink/CE examples.

    Best regards,

    Vincent
