Compiler: armhex undocumented option

Straight binary output.  But you don't want to use it directly.  

I presume you want to create a binary image from the .out file created by the TI ARM linker. 

If you have access to a Unix-like system, then use objcopy.  If you don't, then use the script tiobj2bin from the cg_xml package.  Under the hood, tiobj2bin uses the hex utility -b option.  These methods presume you are comfortable working on the command line.  If you build with CCS, you can configure a post-build step to use tiobj2bin.  There may even be a pre-configured post-build step you can use.  Details are in the Pre and Post Build Steps section of the larger article Projects and Build Handbook for CCS.  

Thanks and regards,
