Linux/AM5728: How to compile ARM executable using CCS

Edmund Carvalho

Part Number: AM5728

Tool/software: Linux

Hi ,

I need to compile an arm application into an executable file that I can copy to the rootfs of my board and run.
I have the ti_linux_sdk and am able to cross -compile simple hello world application from command line using the compiler linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf-gcc.

I want to compile codebase in CCS instead of writing my own makefiles,

my application uses TI_IPC and other ti libraries.

How can I Setup CCS project to compile the same ?

Hello and thank your for your post.

I believe the following guide will be very helpful to you:

processors.wiki.ti.com/.../Processor_SDK_Linux_Training:_Hands_on_with_the_Linux_SDK

It is a bit out of date, but the overall process has recently been validated with current SDKs. It should certainly help get you started. Further down in the guide it shows how to use Remote System Explorer to transfer the files as well.

I hope this is helpful to you.

Hi RonB,

Thanks, I was able to compile simple projects with standard libraries.

I need to compile code with Ti specific libraries like IPC, NDK etc... from the Linuz SDK .
Could you point me to any documentation on how to link these libraries to a CCS C project for ARM.

Thanks & Regards,
Edmund.

Edmund,

Please take a look at our IPC documentation to get a feel for developing IPC applications from both the host Cortex-A device and the slave DSP, MCU, etc.

http://software-dl.ti.com/processor-sdk-linux/esd/docs/05_03_00_07/linux/Foundational_Components_IPC.html#ipc

It will have different examples for how to build IPC code. Some are from Linux and some are from RTOS.

Building the NDK from Linux is not a use case we support. The NDK should only be used by RTOS application and are documented as such.

I hope this is helpful to you.

Hi RonB,

Thanks for the speedy replies.

I agree NDK is meant for RTOS, I mentioned it by mistake.

The link you shared describes how to build ipc examples using readymade makefiles and not CCS compilation.
I will go through the makefiles and see if i can catch any hints .

Thanks & Regards,
Edmund Carvalho.

Edmund,

Yes, on the Cortex-A side, we tend to be more Linux centric. You might want to look further into the Processors SDK for RTOS as it is more RTOS centric and likely to be more correlated with CCS. Here is the RTOS documentation:

http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_Foundational_Components.html#ipc

I hope this helps you further. Thanks for getting back to us.

Hi RonB,

We decided to write our own makefile for our ARM code instead of using CCS,
I found that sourcing /ti/linux_sdk/environment-setup exports all the relevant paths from the Linux SDK.

This link provided few insights on how to cross compile code using the Linux SDK.

Thanks for the Help.
