Hi Umesh,
I guess you have forgotten to add -mfloat-abi=softfp or hard option to
GCC.
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.
