map file the linker has placed the .stack and .sysmem sections in flash rather than RAM.

To get the program to run I had to add the following to the SECTIONS of the project  TMS570LS202x6SFlashLnk.cmd:

    .stack   : {} > STACKS
    .sysmem  : {} > RAM

 Should the C:\ti\ccsv5\ccs_base\arm\include\TMS570LS202x6SFlashLnk.cmd supplied with CCS 5.1 be updated to add the .stack and .sysmem sections generated by the compiler?

It also looks like the TMS570LS212xFlashLnk.cmd, TMS570LS213xFlashLnk.cmd and TMS570LS313xFlashLnk.cmd files have the same problem of missing sections.

    Hi,

    Thanks for reporting this; I will contact the owners of this file and request a fix.

    Was a fix requested for this?

    I checked in CCS 6.1 (under Linux) and the .stack and .sysmem sections are still missing from the TMS570LS202x6SFlashLnk.cmd file.

    Also, in CCS 6.1 the "New CCS Project" dialog for a TMS570LS20216SPGE leaves the Linker command file blank by default

    Should the TMS570LS202x6SFlashLnk.cmd file be selected by default when a new project is created in CCS 6.1 for a TMS570LS20216SPGE?

    Chester,

    I talked to the applications team that works with the Hercules device support for CCS, and they are looking into it.

    However, they also mentioned that HalCoGen linker CMD files are better suited for Hercules development, thus recommended by them.

    I will let you know if/when these changes are implemented. For now, check the page below that helps with the integration between HalCoGen and CCS:

    processors.wiki.ti.com/.../Creating_new_CCS_v5_Project_with_HALCoGen

    Thanks for the information.

    Looking at the http://processors.wiki.ti.com/index.php/LAUNCHXL2_RM46:_Project_0 shows that HalCoGen uses a different approach to allocating the stack than than the TI ARM compiler run-time library:

    a) HalCoGen projects use their own start-up code, with the _coreInitStackPointer_ assembler function setting the stack pointers to hard-coded values. The Linker Command file generated by a HalCoGen project uses a memory region named STACKS, which overlays the stack addresses set by the _coreInitStackPointer_ assembler function.

    b) Whereas if a new CCS only project is created for a Hercules device, the start-up code in the TI ARM run time library is used, which requires a .stack section in the linker command file to define which memory region the stack is placed in.

    The "default" Hercules linker command files in CCS are in the format used by HalCoGen, in that they define a STACKS memory region rather that a .stack section.

    For now I will use HalCoGen and CCS integration as suggested.
