Junqing Zhao I try to convert my old DM6437 projects (done with CCSV3.3, bios support) to CCSV5.1.I have add all relevant library
Did you import the CCS 3..3 project into 5.1 using the import wizard, or did you recreate a new project in CCS 5.1? Typically the DVSDK projects designed for CCS 3.3 require some work after importing into CCS 5.1 to get it to build. In some cases it might be easier to create a new project in CCS 5.1 rather than try an import.
The linker errors you are seeing are because the BIOS libraries are missing. Check your project view in CCS and see if the .tcf file is being excluded from the build. If it is, go to its Properties and uncheck the setting which "excludes it from build". I have seen this happen with other DVSDK projects that I have tried importing (for a different device though). If the .tcf is not built, it will not generate the linker command file which in turn will link in the BIOS libraries. You may give this a try, or try creating the project from scratch.

I have used the import wizard. Some projects can be successfully converted,while others have a lot errors. One big problem is that head file (.h) and library file(.lib). Some of these files have many versions,which are located in CCSV5 is the new ,that is different with what I have used. Which I can use correctly?
In CCSV5.1,the CGTOOLS version is 7.3 and the BIOS is 5.4.31 as default.which is different with what I used in CCS3.3. Then how can I solve this to migrate the projection successfully?
Depending on how the original project was created and its complexity, the import wizard may or may not be able to "convert" it to CCSv5 in a clean manner, which is why some additional work would be needed to get the project working after import.

In general, using the latest versions should be ok, but this may really be dependent on the project. You can try setting it to use your older version and see if that works better.

You can set CCSv5 to use a different version of CGT and BIOS than the default. This page tells you how to do it. For CGT you should be fine using the older version that you used with CCS 3.3. For BIOS, although you can still use BIOS 5.3.x it is advisable and recommended to use 5.4.x and higher with CCSv5 to avail of the BIOS debug tooling. http://processors.wiki.ti.com/index.php/DSP/BIOS_Support_in_CCSv4
