Big endian and little endian on EVM6472

Hi,

is it possible to run big endian apps on the EVM6472 board.

I just tried to compile and run the hpdspua demo application in big endian mode and got the following error: 

mcsdk_1_00_00_08/packages/ti/platform/lib/platform_utils_evm6472
   .lib<platform.obj>" = little endian

Is it possible at all to run a little endian app on one core and a big endian app on another core of the c6472?

Best regards, Carsten

    Carsten,

    It seems that at least some of the libraries are built for little endian, which would cause the error. In this case you will need to rebuild all the libraries or at least include the ones already built for big endian.

    The endianess is a device-wide configuration set by the pin LENDIAN. Check page 29 of the datasheet and page 43 of the EVM manual.

    Hope this helps,

    Rafael
