Issues migrating from TMS470 compiler v4.1.1 to version 4.6.6

The same code base built with v4.1.1 will build with 4.6.6 but will not run on the OMAP1710. This processor requires COFF I believe and i have tried the --abi=ti_arm9_abi option but still it isn't working.

Any specifics to things that should be looked into when upgrading to a later compiler?

    You are probably correct in saying that COFF is required.  But it isn't the processor that requires it.  It is the software which gets the executable bits on to the processor which cares.  This could be a loader, or a flash burn utility, or something like that.

    Please be more specific.  What exactly is going wrong?

    Thanks and regards,

    The device will no longer power up. The bootloader tranfers control to the image and it seems to hang or get stuck. Unfortunately we no longer have jtag capability on our product .

    I only need the linker (lnk470.exe) of 4.6.6 to resolve a linker OUT OF MEMORY: APPLICATION ABORT issue that occurs when compiling with --gen_func_subsections.

    The linker options used now with 4.1.1 are:

    -a -x -priority -q -w -c -m

    Are there some new defaults that I need to modify for 4.6.6 linker?

    A change in the linker defaults would be a pretty big deal.  I checked the README.txt file that you can find the root directory of the compiler installation.  There are some new features in the linker, but no changes in the defaults.

    I'm sorry, but there is little we can do until we have a better description of the problem.

    Thanks and regards,
