Linux/BEAGLEBK: unable to compile linux system based header files compile in ccs , but able to compile in beagle bone root directory which include am335x sdk (5.0.02) using gcc compiler .

Manoj,

These instructions are a bit out of date, but the overall process is the same with newer SDKs and versions of CCS:

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

Can you please refer to this and see if it provides what you need to be able to build? Thanks.

unable to compile below code in ccs . giving a error .

/opt/ti/ccs900/ccs/tools/compiler/gcc-arm-none-eabi-7-2017-q4-major/arm-none-eabi/include/termios.h:4:10: fatal error: sys/termios.h: No such file or directory.

but same code i copied to beagle bone root directory and able to compile and execute . in beaglebone booted the linux using sd card of ti-am335x sdk .

fd = open(port, O_RDWR); /* connect to port */

/* set the other settings (in this case, 9600 8N1) */

// read(fd,&buff,sizeof(buff));
printf("message : %s \n", &buff);

}

close(fd); /* cleanup */
}

Manoj,

You just repeated your first post without any additional information. Did you follow the guide and configure a CCS project per it's recommendations? It doesn't seem so as it is not using the Cross Compile Toolchain that needs to be used to build this code.
