    Dear all,

    The default optimization options to compile the software in the BSP of DM37x torpedo module are '-O2 -fsigned-char -mfloat-abi=softfp -mfpu=vfp', however TI suggests that the optimization options for the same processor should be: '-march=armv7-a -mtune=cortex-a8 -mfpu=neon -ftree-vectorize -ffast-math -mfloat-abi=softfp' [1]. As you see, these options improve the usage of NEON. I would like to know why they are not applied.

    Thanks and Best Regards,
    Joaquim Duran
