TMS470/TMS570 flash programming with GCC

Other Parts Discussed in Thread: F035FLASHAPI

I am writing a bootloader for the TMS470 and am using a GCC toolchain. I have a basic system running, but am unable to link with the provided flash API from http://www.ti.com/tool/f035flashapi

The file pf035a_api_eabi.lib is an archive containing object files. However, the GCC toolchain is unable to read them:

$ arm-none-eabi-objdump -x feed_dog.obj
BFD: feed_dog.obj: don't know how to handle processor specific section `.TI.symbol.alias' [0x7f000006]
arm-none-eabi-objdump: feed_dog.obj: File format not recognized

I am using CodeSourcery (Mentor) release830. This is gcc-4.3.3 based.

Linux binaries, Windows binaries and sources are at:
https://sourcery.mentor.com/sgpp/lite/arm/portal/release830

Is source code available for the library so I can recompile it myself for GCC? Or, a binary version which works with the GCC tools?

Thanks.

Hello jrt,

Are you working on a linux or windows os?

I will work on getting this resolved and get you an object library that will work with the CodeSourcery tools as soon as I can. I will be traveling 11/28 - 11/30 so I will not have a chance to look into this until the end of the week. I will try to get you a preliminary answer the first part of the week of Dec 5th.

I'm working with Linux (Ubuntu 11.10).

Thanks, I look forward to a solution.

Unfortunately this is a bug in the compiler. We create a special section in the object file that contains information on functions we can remove because they are aliases for other functions. The compiler was creating this section with a special section type that is not defined in the ARM EABI. This issue has been fixed and will be available in the 4.9.3 release which is scheduled for mid January. I do not know of a workaround in the current tools for this issue. The problem only exists starting with the 4.9.x version of the compiler, so you could revert to the 4.6.x version until 4.9.3 is released.

I'm also having the same problem trying to link the F021 API (F021_API_CortexR4_BE_v3D16.lib, v1.50.0) in with GCC 4.6.2 (armeb). Do you have any idea when a fix will be available for this version?

Andrew, jrt,

We believe that this issue is due to a known bug with the compiler (TI's CGT 4.9.x) used to build the F021_API lib. An updated compiler release (v4.9.3) including a fix to this known issue is slated for January. How soon would you need to get this sorted out and would you be interested in evaluating a Beta release?

This is currently blocking me from making progress, so I would be very interested in trying a beta version, or any workaround that you may have. Please let me know how I can get a new version to try. Thanks.

Andrew,

Is this question still open?

I was able to get an alpha version from TI that has a fix for this issue. I'd love to know when the next official release is out (I've heard sometime in January), but in the mean time I'm making progress. Thanks for the follow up.
