Will the labs from the "OMAP/DaVinci/Sitara System Integration using Linux" workshop work on the TMDSEVM3730?

I have run through the workshop labs on a DM3730 EVM and they seemed to work fine, though I don't believe I was running them at the higher frequency available to the DM3730, I suspect that would work fine as well.

Question:  How do I resolve the path errors and the linker errors in the DaVinci Workshop lab 13?

The details: I am able to run the labs on the DM3730 and working through minor changes and completed lab 12.  Then lab 13 proved to be a chalenge at step 16.  I am using CCS 4.2.5 and it does not have the option for "Empty RTSC Project" and thus I used the instruction for the work arround:  http://processors.wiki.ti.com/index.php/Empty_RTSC_Project_Workaround . I am able to manually creating the 3 projects follwing exactly the directory for the workshop 
  C:\workshop\labs\lab13a_build_algo\tto\app\mixer;
  C:\workshop\labs\lab13a_build_algo\tto\app\mixer_tto_app_configuration;
  C:\workshop\labs\lab13a_build_algo\tto\codecs;

The "tto.codecs.mixer" project built just fine. However the application project giving a lot of trouble. Since the new CCS's installed location default at  "C:\Program Files\Texas Instruments"  versus what the workshop has "c:\ti";  --  I had to work through some of the paths defined in the  "mixer_tto_app" project: Built Properties | Tool Settings | Inclue Options -- for the following:
 main.c 
   #include <xdc/std.h>                             //STT added path  "C:\Program Files\Texas Instruments\codec_engine_3_22_01_06\cetools\packages"
   #include <ti/sdo/ce/CERuntime.h>    // STT added path C:\Program Files\Texas Instruments\codec_engine_3_22_01_06\packages
   #include <tto/codecs/mixer/mixer_tto.h> //STT added path   C:\workshop\labs\lab13a_build_algo

 std.h
   #include <ti/targets/select.h>      // STT added path C:\Program Files\Texas Instruments\xdctools_3_22_01_21\packages

 Then when I finally get pass the compiler, I got the following linker error:

  undefined                          first referenced
  symbol                                in file    
 ---------                          ----------------
 _CERuntime_init                    ./main.obj     
 _Engine_close                      ./main.obj     
 _Engine_open                       ./main.obj     
 _UNIVERSAL_control                 ./main.obj     
 _UNIVERSAL_create                  ./main.obj     
 _UNIVERSAL_delete                  ./main.obj     
 _UNIVERSAL_process                 ./main.obj     
 _ti_sdo_ce_osal_Memory_contigAlloc ./main.obj

 It seems like the is a missing path to the library but I could not figure it out where is the library?

Thanks for your help in advanced.

Could you also tell me how the 3 projects dependncy in lab 13a are inter related? What I have as Project | Properties | CCS Build | Dependencies -- are:

mixer_tto_app  -- referenced Project  -->  mixer_tto_app_configuration  & tto.codecs.mixer

Furthermore, when I use the the source file from the solution directory to run the lab13b, it built OK on the Ubuntu environment and created the "app_debug.xv5T". But it fails at runtime. It gives me this error reporting  via teraTerm. Please tell me what is missing that cause this failure?

That seems like a pretty low-level error, i.e. is that file missing or something?  Is the name slightly different?  When you do a build all of the references are relative to the build directory (e.g. "Debug" or "Release") so ../mixer_tto_app_configuration.tcf would be in the level just above Debug/Release, e.g. typically the project root directory.

Brad,

I think the file is dynamically generated as it stated in the first line of the built. I think I am have something missing or pointing to the wrong place so that this .tcf file was not built correctly.

The tcf is never generated.  If you're missing the file it won't build.  I imagine the project from the workshop has a tcf.  Did you accidentally delete the file or forget to copy it over?

Brad,

Below is the list of the starter files for lab13.  If all the links in the tools setup correctly, then it should generate the "mixer_tto_app_configuration.cfg".  I tried to built with CCS 4.2.5.  I also tried with CCS 4.2.4 on a different machine that install CCS under c:\ti directory to map with the path in the workshop. One caveat different from the workshop installation is both of these CCS installations have "codec-engine_2_25_05_16"  but no "\cetools" subdirectory.  I had to nabually install "codec_engine_3_22_01_06" which has the subdirectory "\codec_engine_3_22_01_06\cetools" and then make a the path update manually.  I suspect that the issue might be in my built file "xdcpath" - but as you noticed in the error output, it reports the path correctly with the newer codec_engine_...

You should instead manually install the latest version from the Codec Engine 2.xx tree.  There are many dependencies under the hood.  In particular, the following components "go together":

• Codec Engine 3.x, Sys Link 2.x, Sys BIOS 6.x
• Codec Engine 2.x, DSP Link 1.x, DSP BIOS 5.x

For OMAP3530 and DM3730 you will want to stay on the latter set of components.  Eventually when you migrate to DM816x (or other new device) you'll need the first set of components.  I think the migration will merit a new thread...

For now I recommend staying with the second set of components that I listed and let's see if we can get it all working.

Brad,

--------------------------

3 *** The  tool  generated an empty with a 0 byte  "mixer_tto_app_configuration.cfg" file which causes the  "mixer_tto_app_configuration" project to fail. Hence I suspect also caused the 

"mixer_tto_app" to fail - which has a dependencies on the *_configuration project & the tt.codecs.mixer project.

Can I get a copy of the "mixer_tto_app_configuration.cfg" file? And can I get the printout for the expected message when things a built correctly?

It's hard to tell exactly what's going wrong without your actual project. That said, here's a couple of things to look at: (Note, I don't have any experience with Codec Engine (CE) version 3.x or XDC  3.22. Speaking from experience, different library versions can be significant.)

Looking at your first build problem, you've got a version issue. The project we built for the workshop was based on DSP/BIOS 5.xx, which uses a BIOS configuration file with the .tcf extension. In your case, though, you're building the same project using SYS/BIOS 6.32, which uses a different configuration file format.

At least for getting started, I would recommend using the package versions we used in the lab instructions:  CE 2.26, XDC 3.20,  DSP/BIOS 5.41. These should work fine for the DM3730. At some point in the future, when you move to a new processor, you'll need to upgrade to the later versions of these libraries ... but it might be better to tackle that after getting a bit more experience.

Other than the RTSC package repositories specified in the lab directions, you shouldn't need to add any others. The directories added to the #include statements should provide the proper references that are needed. Basically, the package repository paths are automatically added to the build settings (once we've added them in the GUI); the #include statements (such as "ti/sdo/ce/CERuntime.h") provide the necessary reference from the root of the package. This is pretty standard style for RTSC builds --- although, this is one of those things that occassionally gets tweaked between package versions. I haven't analyzed the differences between CE 2.26 and 3.22, but it wouldn't surprise me if things were modified a bit with all the changes implemented in v3.xx.

As a side note, the latest versions of CCS v4.2x changed the new project wizard somewhat. When I built the project again tonight (with a more recent version than we were using last summer), it didn't offer to let me build a configuration project. Though, I was able to add the configuration files (.cfg, .tcf) directly to my application project. In a way, this was a bit cleaner (i.e. more simple) that it was in earlier versions of CCSv4.

Finally, I so much dislike putting spaces in tool paths, which is why we installed CCSv4 into the "C:\TI" directory. (BTW, I think this is actually the default for CCSv5.) Even so, I don't think the installation differences should make much of a change to these projects - other than the reference to the BIOS package path we need to include to our app project..

mixer_tto_app  -- referenced Project  -->  mixer_tto_app_configuration  & tto.codecs.mixer
mixer_tto_app_configuration  -- referenced Project  -->  tto.codecs.mixer
tto.codecs.mixer  -- no dependency

Actually, if I remember correctly, the mixer_tto_app project just referenced the configuration project - which included the references to the tto.codecs.mixer package (i.e. library). As I mentioned in my earlier email, the later versions of CCS v4.2x don't force you to create a separate configuration project. (In fact, they didn't even give me the option when I tried it tonight.) Effectively, the configuration source files (.tcf and .cfg) can now be included right into the application project.

I didn't see Brad's responses until just now. It appears he and I are stating the same thing. You need to be using different versions of the Codec Engine, XDC, and BIOS libraries. At least, this is the case when using the files we provided for the lab exercises.

The TCF file is not autogenerated, we provide this file as part of the application starter files. It is designed to work with BIOS v5, so it's no surprise you're getting an error trying to build it with later versions of those library packages.

---

Furthermore, when I use the the source file from the solution directory to run the lab13b, it built OK on the Ubuntu environment and created the "app_debug.xv5T". But it fails at runtime. It gives me this error reporting  via teraTerm. Please tell me what is missing that cause this failure? 

root@omap3evm:/opt/workshop# ./app_debug.xv5T
Program 'universal_test': Engine 'myEngine' opened with handle = 0x4f4e8
Program 'universal_test': ERROR: Can't open algorithm 'mixer'

With regards to you last issue, there just isn't enough info to tell what's causing the problem. It appears the Engine is being opened, but that the algorithm isn't being created -- which means everythihg else after that will fail. The most common error is that the string name for the codec, between the ARM and DSP, don't match. But it's hard to tell without more information about your build environment.
