Hello  Sir/Madam,

I am using MK60FN1M0VLQ12 (COTREX-M4) processor for my development.

I am using float and double data types in my code. When I perform any mathematical operation on these variables, the processor goes to Hard Fault Exception.

Earlier I have used GCC  4.5.2 compiler for my compilation

So now I am using Linaro’s GNU-GCC Toolchain 4.6.2 for compiling my code with following command.

Hi Akash. Could you confirm which compiler you are using. Is it this one: http://launchpad.net/gcc-arm-embedded

or this one: https://launchpad.net/linaro-toolchain-unsupported

If you run 'arm-none-eabi-gcc --version', what version number does it show?

arm-none-eabi-gcc -Wall -mfpu=fpv4-sp-d16 -mfloat-abi=softfp -mcpu=cortex-m4 -mthumb -Qn -Os  -mlong-calls -c main.c -o main.o

But I am getting following error while linking my code

ld: section .text.startup loaded at [00032258,000331cb] overlaps section .InitializedVariables loaded at [00032258,00032787]

The link file is attached with this mail.

I couldn't find the attachment. Could you resend it please?
