Compiling custom xdc.runtime

Varun Patil

I would like to modify the file text.c in xdc.runtime (specifically, the xdc.runtime.text module). After that, I would like to compile and generate the file packages/ti/target/arm/rtsarm/lib/ti.target.arm.rtsarm.aem3 file. I looked at the http://rtsc.eclipse.org/docs-tip/Working_with_xdc.runtime tutorial and this is what I did.

cd <xdctools_dir>/packages/ti/targets/arm/elf/

<xdctools_dir>/xdc clean

<xdctools_dir>/xdc

But, I wasn't able to generate a new ti.target.arm.rtsarm.aem3 file. Even running the same commands from <xdctools_dir>/packages/ti/targets/arm/rtsarm did nothing. I just want the steps to recompile ti.target.arm.rtsarm.aem3 after changes to xdc.runtime.text.

Any help much appreciated.

Thanks.

    What happens when you go to ti/targets/arm/rtsarm and run 'xdc'? What's the output? As described in the linked tutorial, you have to use config.bld that defines rootDir for your target, which seems to be M3 ELF.

    Hi,

    Thanks. Your mention of config.bld got me going. I used the following config.bld in the directory packages/ti/targets/arm/rtsarm/ to compile ti.targets.arm.rtsarm.aem3

    var M3 = xdc.useModule('ti.targets.arm.elf.M3');
    M3.rootDir = "cgtarm-4.9.0"

    /* specify the target(s) to use when building source files */
    var Build = xdc.module("xdc.bld.BuildEnvironment");
    Build.targets = [M3];
