compiling standalone applications alone

[garimella]

Currently Hello_world.c gets compiled alone with uboot. What should we do to compile hello world alone without compiling uboot?

[Pavel]

Look at the following page install standalone toolchain:

https://freescale.sdlproducts.com/LiveContent/content/en-US/QorIQ_SDK/GUID-16DBC8E2-9A18-4867-9BE1-1...

Build and install the standalone toolchain with Yocto:

$ source ./fsl-setup-poky -m <machine>

$ bitbake fsl-toolchain

$ cd build_<machine>_release/tmp/deploy/sdk

$ ./fsl-networking-eglibc-<host-system>-<core>-toolchain-<release>.sh

Note: The default installation path for standalone toolchain is /opt/fsl-networking/. The install folder can be specified during the installation procedure.

Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.

source /opt/fsl-qoriq/2.0/environment-setup-aarch64-fsl-linux

Check result of "source" command. Use "$PATH" command. The "source" command should add path to gcc compiler.

You should see similar message:

$PATH

bash: /opt/fsl-qoriq/2.0/sysroots/x86_64-fslsdk-linux/usr/bin:/opt/fsl-qoriq/2.0/sysroots/x86_64-fslsdk-linux/usr/bin/../x86_64-fslsdk-linux/bin:/opt/fsl-qoriq/2.0/sysroots/x86_64-fslsdk-linux/usr/bin/aarch64-fsl-linux:/opt/fsl-qoriq/2.0/sysroots/x86_64-fslsdk-linux/usr/bin/aarch64-fsl-linux-uclibc:/opt/fsl-qoriq/2.0/sysroots/x86_64-fslsdk-linux/usr/bin/aarch64-fsl-linux-musl:/ltib/QorIQ-SDK-V2.0-20160527-yocto/sources/poky/scripts:/ltib/QorIQ-SDK-V2.0-20160527-yocto/sources/poky/bitbake/bin:/ltib/Freescale-Linux-SDK-for-LS1021A-IOT-Rev2-v0.4-20150907-yocto.iso/poky/scripts:/ltib/Freescale-Linux-SDK-for-LS1021A-IOT-Rev2-v0.4-20150907-yocto.iso/poky/bitbake/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:

$CC test.c --sysroot=/opt/fsl-qoriq/2.0/sysroots/aarch64-fsl-linux  -o test.elf

Have a great day,
