DSP6747 little endian and big endian, waiting on line

    Now, I have several questions about DSP6747, as follows:

1→Does DSP6747 support big endian.

     I use CCS5.2 IDE, the property selection shows it supports little endian and big endian.as the picture below:

But when i choose big endian property, the ccs5.2 console error.as follow:

I use SEED-XDS560PLUS emulator.

my question is: Does DSP6747 support big endian mode?

2→My project has many data interface, some of them are little endian mode, the others are big endian mod. Now i'd like to use only little enidan mode, but the source data length is not fixed. I hope to change big endian data to little endian data, any good methods?

                     thanks!
