cgtools v5.2.1 Link Errors

I need to see what is in your linker command file.  Please post it.

Thanks and regards,

With the permission of the lead, the relevant portions of the command file is included below.

Looking over your link command file, and your first post, made me realize you are probably linking without --rom_model (AKA -c) or --ram_model (AKA -cr).  And that's why your link works under CCS v3.3.  When you moved your project to CCS v4, one of those options somehow got set.  So please try this.  Bring up your project Build Properties.  Select C6000 Linker | Runtime Environment.  The selection Initialization Model is a drop down box with 3 entries.  Choose the empty one.  I'm confident, though not certain, this will solve your problem.

Thanks and regards,

I changed the linker setting selection as suggested (i.e. setting runtime env to "none"), but that did not do the trick.

I assume that there is no way to avoid the run-time code and data, is that right? 

The link command file dumps all the run-time stuff to PAGE1 which does not have any memory assigned, and the v4.1.3 linker takes it just fine.  I have verified down-grading the cg tool back to  v4.1.3 instead (but still using the same project in ccs4), and the errors went away. 

btw. my processor is TMS320F2812.

Thanks!

I do not understand how you ever got the v4.1.3 linker to work.  I have tried my own small test cases and failed.  To make progress on this, I need some sort of test case which builds clean under v4.1.3 but fails under v5.2.1.  I realize that may be lot to ask.  But I see no other alternative.  If it helps, you can send the test case just to me, and not post it here.  Click on my name or avatar, then "Start Conversation".  The interface which comes up includes an icon for attaching a file.

Thanks and regards,
