Migrating from CCS V3.3 to CCS V5.1 - Is this my best option

Other Parts Discussed in Thread: TMS320C6701

We are currently developing s/w for our TMS320C6701 DSP using CCS V3.3 and XDS510PP+ emulator on a PC running XP. We have purchased the XDS510USB emulator and have gotten it to work with our PC that is running XP. We had purchased the new CCS license a while ago and are now migrating. I had played with CCS V4 and had issues...not all of them were resolved. Same when I tried playing with CCS v5.1 back in January. I'm now back to the task and see that the latest release is V5.3. I'm wondering if migrating to V5.3 is my best approach. So far, with CCS V5.1, I have the following issues:

1. My code, in the mainline, has a call to  cslCfgInit();. In TI ticket # 1-755281159, it was suggested that I include cfg.h. This file could not be found by the compiler and so the issue was never resolved.

2. I commented out the call to cslCfgInit(). Now I get compile errors with sin and tan functions. I don't call these functions. Probably part of some library. Not sure what to do about this issue.

3. I tried to setup the ccxml file to verify that CCS can comunicate with the emulator. An option appears for the XDS510USB emulator but the 6701 is not listed under supported devices.   Not sure what to do about this issue.

These issues make me hesitate about migrating to CCS v5. Anybody have some opinions about how I should proceed? Should I stick with CCS V3.3 while using the old DSP and migrate to the new CCS when we start using newer DSPs? Any input would be appreciated. Thx, Bill.

    Note that CSL does not ship with CCS like it did with CCSv3.3:

    http://processors.wiki.ti.com/index.php/Importing_CCSv3_Projects_into_CCSv4#CSL_and_XDAIS

    You need to point CCSv5 to the CSL existing in your CCSv3.3 install or download a standalone version and point CCSv5 to it:

    I'm sure removing that main call to initialize CSL will have a negative domino effect. Download and install CSL as mentioned above

    6701 is not officially supported by CCSv4 and 5. You will need to create a custom target configuration for it:

    I created one for you (assuming you are using spectrum digital emulators) and attached it to this thread

    It is up to you. Some people do this while others just want to deal with one development environment.

    I also attached some slides on training for using CCSv5 for the v3 user that may help

    Thanks

    Hi Ki-Soo Lee,

    All your suggestions worked perfectly. This worked far more smoothly than when I tried to migrate back in January.

    The only issues I had were lots of 16002 warnings and the call to cslCfgInit() to init my EMIF rgtrs. The warnings are a result of legacy libraies for the CSL. I suppressed the warnings by adding “--diag_suppress=16002" to the linker command-line pattern field. I added a prototype for the external call and then compilation went well.

    The ccxml file you sent me also worked on the 1st try.

    Many thanks for making this migration so smooth.

    Bill.
