Hi,

I am trying to build bluetopia for wl18xx chip on imx6 sololite processor and using 3.0.35-2508-g54750ff kernel version.And  i am facing the below errors.

~/AM335xBluetopiaLinuxProduction-4.0.3.0.1.0/build$ make all

    Hi Samiksha,

    The errors you are seeing is because of the following reason:

    - The TI-BT-STACK-LINUX-ADDON is built using the PROCESSOR-SDK-LINUX-AM335X and the libraries in the TI-BT-STACK-LINUX-ADDON were compiled using the toolchain included in the PROCESSOR-SDK-LINUX-AM335X. This toolchain supports hardware floating point (CFLAGS += -mfloat-abi=hard) as default in all Sitara Linux SDKs. 

    - From the error messages above, it looks like your current toolchain rules are set to -mfloat-abi=soft.

    - As explained on this wiki page, the libraries compiled using one -mfloat-abi=hard compiler option are not compatible with soft floating point and vice versa. 

    Solution :

    - As mentioned here, looks like the gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain that you are using also supports the -mfloat-abi=hard compiler option. You will need to use this compiler option in your toolchain to avoid the VFP register arguments error.

    Best regards,

    Vihang

    Thanks Vihang for this.

    But we have already tried by changing the -mfloat-abi=soft to -mfloat-abi=hard and vice-versa, but still the same error we are facing.

    If that is the case, you will need to
    (i) rebuild your kernel from the source code with the right -mfloat-abi setting and avoid the error you are getting.
    (ii) use a toolchain that supports hard floating point out of the box.

    BR,
    Vihang
