Hi Umesh,

I guess you have forgotten to add -mfloat-abi=softfp or hard option to

Please run the following command line in your terminal:

$>  echo | arm-linux-gnueabi-g++ -mfpu=neon -mfloat-abi=softfp -dM -E -
| grep -i "version\|neon"

You should get something similar:

#define __GXX_ABI_VERSION 1002
#define __VERSION__ "4.4.3"
#define __ARM_NEON__ 1

Check if the __ARM_NEON__ macro is set.

So, the -mfloat-abi=softfp or hard option - with the -mfpu=neon one -
will enable the NEON for FELighting.
