lnk470 intensive cpu usage under win7 64bit

Hi,

I have an issue with linking a project using TMS470 for Cortex-M3 on a win7 x64 machine.

I have tried debugging this as far as I could, and it seems looping on HeapFree() or something - but I am far from certain.

I didn't see any open issue except SDSCM00039957, which did not seem to progress any further.

Best regards,

Jigal

    Forgot to mention:

    The TMS470 tool version is 4.8.0B1, which is the latest pre-4.9.x release we can use.

    (we can't use the 4.9.x tools since they crash on packed bit-field structure access according to open issue SDSCM00043502).

    Version 4.7.1 seems to work better.

    Best regards,

    Jigal

    Igal,

    We have noticed runtime issues on Windows 7 related to dynamic memory allocation. The issues we are aware of are resolved in the later 4.9.x releases (I believe 4.9.1 has the fix, but 4.9.5 will definitely have the fix). There is no guarantee that the implemented fixes will resolve the issue you are experiencing, but it is very likely. You can try using the 4.9.5 linker with your 4.8.0B1 object files to see if the issue is resolved. You should not experience any issues by using the linker from a later release.
