help with hello world, DSK6713

Darrell,

Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages. Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics.

And thank you for already being a leader in the Community by replying with helpful advice to a user.

I do not remember seeing braces in the compiler arg list. Is "-mvc671x{-mv6710}" the way it printed out to your screen or is it annotated? This is probably very relevant since each of the builds has the warning line below.

>> WARNING: invalid version 0, defaulting to 6200

The three sets of errors all look alike and they all have to do with csl_chiphal.h. My copies do not match with yours, in fact mine do not have a non-comment line with FADCR, at line 1041 or any other. Mine are also at least 5 years old, so your newer version is the best choice, of course.

The -mv is probably the problem, though. Fix it and see how things work.

What you have at the top of your first post here is great documentation of what you have done. One thing about the GEL file: The GEL file can be attached to the Target Configuration so it will run automatically when the emulator is connected and when you load or reset, depending on which commands are defined in the GEL file.

Please report here what you do to get one of the Chassaing examples to work with CCSv5. There have been others who wanted to do that, and you can continue your leadership role.

RandyP

Thank you Randy,

I took out the listed compiler target and changed it to "6700", as in some of the examples that came with the Spectrum Digital download.  I also noticed that the program is slightly different from the text, so I went in line-by-line to make it "exactly" as the text  This cleaned up the 6 errors, as you predicted.

I'm trying to be as detailed as I can as I work through setting this up.  Hopefully it will save someone else a few hours.

Now, about the warnings:

There were a few functions that needed to be prototyped in the sine8_LED.c file.  I carefully traced back all the headers, and found that two functions were in headers that were not referenced, so I added two headers to declare a few functions like DSK6713_DIP_on() and DSK6713_LED_on() that exist in the sine8_LED.c code.  In addition,  one of the functions takes a Uint argument to specify "which" LED gets enabled--which was not in the code.  I suspect the function may have changed over the years.

#include "dsk6713_led.h"
#include "dsk6713_dip.h"

While I was dealing with headers, I added inclusion guards around "C6713dskinit.h" in case it was referenced more than once:

#ifndef C6713_DSKINIT_

#define C6713_DSKINIT_

...(header code)...

#endif

That cleaned up the " warning #225-D: function declared implicitly" except for two declarations I added to the sine8_LED.c code.

void comm_poll();               
void output_left_sample(short out_data);

The comm_poll() function is defined in c6713dskinit.c and prototyped in c6713dskinit.h.  Simply adding #include "c6713dskinit.h" to the sine8_LED.c file doesn't work.  It spits out  a few errors:

**** Build of configuration Debug for project my_sine8LED ****

gmake: Target `all' not remade because of errors.

**** Build Finished ****

Adding the prototypes to the sin8_LED.c program seems to work.  It compiles with warnings, but no errors --yeah!:  So, I have a sine8_LED.out file, but it won't load on the board.  Note the last warning at the bottom.  Looks like linker/memory issues, so I'm diving into:

http://www.ti.com/lit/an/spraa46a/spraa46a.pdf                      (linker techniques for efficient memory usage)

Any other suggestions to read?  It may be a simple issue of setting up the linker properly.  I'm not too familiar with the ins-outs of the linker.  Hopefully, some of the TI documentation will help.

On a side note, I did get some of the examples and tutorials to compile and load  from the Spectrum Digital site,

http://c6000.spectrumdigital.com/dsk6713/

but I don't know what they "do".  In my most recent update, I have not found any documentation that walks you through the examples and tutorials.  The code is just "there".  Short example:  At the beginning of the sine.c code (from the spectrumdigital site) says:

// ****************************************************************
// Description: This application uses Probe Points to obtain input
// (a sine wave). It then takes this signal, and applies a gain
// factor to it.
// Filename: Sine.c
// ****************************************************************

I'm not familiar with probe points.  Since the program was found in the /tutorials folder, I would have hoped it would have been explained somewhere. :(.  Most all of the tutorials are like that.  I haven't found a meaningful one yet.

Darrell,

Thanks for the detail and for continuing this on the forum. It may be best to remove the Answered flag until we are done, since other support people may not think you still need help. Once you are completely done, then please mark Answered on the best choice post(s).

Adding the prototypes to the sin8_LED.c program seems to work.  It compiles with warnings, but no errors --yeah!:

To me, a warning is as bad as an error because it is something showing up in the Problems window. I want that to be empty. Mainly, this is to make sure I do not miss a warning that is really bad. The warnings in your linker output are really bad.

I think this is due to using the wrong memory model in the compiles. In the Build Properties -> C6000 Compiler -> Runtime Model Options, there is a selection for "Data access model (--mem_model:data). The default may be near, and that may be incompatible with one or more of the libraries since they use the .far section. Change this to either "far" or "far_aggregate" and see if the linker works better.

It is possible that you will want to re-build all of the libraries to make sure they are completely compatible with the newest build tools that you are using. This could also be a factor in the linker warnings.

Re Probe Points: In CCS Help->Search, you can look for probe points and find a little bit of information. I think we have a tutorial for probe points that uses the stairstep example. I think I had a problem getting the stairstep example to build with SYS/BIOS, so there may be a default setting that needs to change for it. I did not look farther, but if you try it and have a problem, start a new thread about that in the Code Composer forum, and please mention it in this thread, mainly for my sake since I do not look through the Code Composer forum very often.

Regards,
RandyP

Randy,

Yeah!  The --mem_model:data = far did the trick to clean up the linking errors. (latest build below). So now, I have a seemingly good .out file, and trying to load it on the board. For comparison, the sine8_LED.out that comes with the Chassaing book loads, and runs as advertised.  The one I build "looks" ok, but unfortunately, it's not running on the board.

Let's see if I can summarize the errors: 

1.  I cleaned, and built the debug version.  I started the debugger, and Code Composer connects and loads my_sine8_LED.out program into the board.  I'm using the Spectrum Digital DSK-EVM-eZdsp onboard USB Emulator_0/TMS320671X, and it starts (Running), instead of (Suspended) as expected. My compiled program does not work, all four LEDs are lit, and there is no tone when DIP(0) is pressed.

2.  I'll press the "pause" button in CCS5 to stop the program, and I get the following error:  Trouble Halting Target CPU:  Errror 0x80000020/-1060, Fatal Error During Execution...

3.  I follow the recommendations to restart..   Disconnect the board, reset the emulator, and reset the board (reset button).  The board re-boots with a good POST.

4.  At this point, I can reload my program, or reload the pre-compiled program.  If I connect, load, and run the pre-compiled program,  I get a working program.   If I connect, load and run "my" program, I'm back where I started (except the program starts without my intervention).  It is not responsive.

I'm still thinking it is something to do with the compile/link settings.  I looked a bit at the CSL, and the BSL, and I'm reluctant to think it's anything in there, unless TI changed formats, and the Chassaing example isn't current.. but in that case, I think I would get hard compile errors, which are all cleaned up.

The other thing I could think of are my "fidgeting" with the source code--  (added headers, and prototypes for undeclared functions).   I took out all my "fidgets" and tested that, but it still doesn't run... and as expected...pick up a few "function delcared implicitly" warnings in the process.  In the end, I don't think it is a factor.

Just to rule out some simple stuff,  I've confirmed that I am loading a freshly built my_sine8_LED.out  and not an old one left laying around.

When you say "rebuild your libraries,"  what are you referring to?  the CSL, BSL, and RTS6700.lib?  These come from TI right?  All I have (I think) are the headers and the .obj files.  Of note, the latest compiler (7.3.8) doesn't have the RTS6700.lib, so I had to use the one-off compiler (7.3.4) to make use of this library.

I feel like I'm making headway.  This is one of the most difficult "hello world" programs I've seen in a while.  End the end though--once I can get through this, I think the rest of the learning curve won't be so steep.  I'd almost want to start debugging the executable, but I don't really know where to start.  This is probably the simplest of simple programs and it "should" work without too much frustration.  At least I'm learning stuff as I try to work through the problem. 

Once I get it running, I'll write up a summary to post on here so others can make the jump easily.  I emailed the guys at Spectrum Digital.  They replied and basically washed their hands of it saying they had no CCS 5 projects they were working on for the DSK6713.  I guess they expect to sell me a board in 2012, and have me roll back to CCS 3.1, (and downgrade my computer as well).

No worries.  We'll get 'er done!

I haven't looked at the probe points yet.  Will do once I get past this hurdle.

Darrell,

I am very surprised that we dropped rts6700.lib. This had to have been intentional, and that means you definitely want to stay with CGT 7.3.4 for now.

1. Hello World would be simpler than this. My first suggestion is to make a true Hello World to see if you can get a program to build and load and run. When you load it, it should run to main() and stop. Then you can Run (Resume) to see the awesome printout on the Console window.

2. When I said to rebuild your libraries, I meant all of them that are not supplied with the compile tools. So csl6713.lib, and dsk6713bsl.lib. Since those were probably built with much older compilers, this would just be a way to make sure there are no compatibility issues. You could put it off a little if you want to narrow down the culprit first, but this may be needed.

3. Please show or attach the .map and .cmd files that you are using, my_sine8LED.map and C6713dsk.cmd.

4. I had a big exam in an EE class in college, and we were told to read through the whole test before starting to work on it. The first four problems were really difficult, like to design a multi-controller system for the elevators in a 120-story office building. Keep in mind this was with an 8-bit micro before K&R wrote their first book on C. The fifth problem was to notice it was April 1st and to go up to the instructor to get the real exam. Nothing related to this thread, other than I think #5 may be the answer and I just now saw it.

5. --analyze_only is something I have never used. I do not believe you want to use it here. If you have a reason for using it, please let me know so I will understand it. But I think it keeps the tool from doing what you really want it to do. Take this out and see how it works. I could guess it was an unusual artifact from the import process, but it was not in your earlier switch lists.

Regards,
RandyP

1.  Got "hello world to work as advertised-- within a DSP BIOS example.  So that's good news.   See attached.

2.  Where to get the source for the CSL and BSL? 

3.  See below:

4.  For a philosophy exam, the prof listed a one-word question:  "Why?"  Most deliberated and essayed for hours.  The guy that answered, "Why not?" got the A.

5. I took out analyze_only.  I may have added that in an attempt to interlist the .asm and .c for debugging.  It's down on the bottom of the "feedback options" page, and was inadvertent.  No luck on fixing the run though.

1.  Got "hello world to work as advertised-- within a DSP BIOS example.  So that's good news.   See attached.

There are three approaches I can suggest to get to a solution.

• Since this is really a tools issue with getting a good build, you could restart this thread in the Compiler forum to get the most expertise from the compiler team. I do not want to push you hard in that direction, but it might be worthwhile to do even while I continue helping you here.
• The outside-in approach would be to start from a runnable example and add in your new code until it breaks, then you would know what is broken. It would be best to start from a non-BIOS Hello world, though, since you do not intend to end with a BIOS project.
• The inside-out approach will be after #5.

2.  Where to get the source for the CSL and BSL? 

Go to the Wiki and search for "C6713 CSL" (no quotes), which you may have already done. In the release notes, it talks about how to extract the source from a .src file that is included in the installation. For the BSL source, it should be in the download from SD, too.

Darrell Thomas said:

3.  See below: [.map and .cmd files]

Nothing looks out of the ordinary in these files.

Darrell Thomas said:

5. I took out analyze_only.  I may have added that in an attempt to interlist the .asm and .c for debugging.  It's down on the bottom of the "feedback options" page, and was inadvertent.  No luck on fixing the run though. 

5a. Do all three of the .obj files get updated date/time stamps when you do a clean build? And the .out file, too?

5b. Try taking out the "../rts6700.lib"; the libc.a is a CGT "trick" that tells the linker to get the appropriate rts .lib file for this build. They might be interfering with each other, but nothing looks wrong in the .map file so I doubt this is a problem. You could also delete the libc.a. There is no need for both of those to be included.

5c. In CCS' Debug Perspective after you have launched the Target Configuration but before connecting to the target (I always do these individually), right--click on the C6713 processor line and select Debug Configurations. On the Target tab under Auto Run Options , uncheck both boxes, in particular "On a program load or restart". This will let the program get loaded and your PC should be at _c_int00. If that does not give you a rational display in the Disassembly window, there is something else major wrong with something in CCS or in the linker outside of your program itself. Make sure the _c_int00 location matches what the .map file said. Now open the source file where main() is and set a breakpoint in there, then tell it to Run/Resume. If it does not reach there, then something in the pre-main() C init code is messed up and you will want to figure out a good way to get down to the failing routine to give you a good guess.

5d. If 5c fails, one alternative is to do the .lib rebuilds to see if there is some new compiler thing that is causing this problem. That is a reasonable probability, and one that the Compiler team would know about really quickly.

5e. Another "if 5c fails" is what I called the inside-out method. Rename main to x_main and put in a main with just Hello world in it. That may not change anything, but it will help to bound the problem some. Start commenting out things in main and other functions, too. Get rid of vectors_poll.asm until you need it, or minimize it down to just _c_int00 if that is in there; it is probably not needed for this early CCS work, but will be for getting all the interrupts running.

would love to write the article.  where do I start?

Darrell,

I am very sorry to have missed responding to your message for 3 months. Very poor turn-around time. Thanks to Pritesh for jumping onto your thread so that I noticed this.

The way I learned to write TI Wiki articles was to go to the Wiki, create an account from the upper-right corner link, then click Help on the left pane and follow the links until I figured it out. I would look at some other articles to see how they wrote things and copy some of those formats. Not that mine are particularly useful, but they are simple and should be easy to follow. One example of mine is What is my DSP clock speed, a single-page article with a couple of pictures and some simple formatting. Another example is Using DSP/BIOS on Multi-Core DSP Devices, which has more pictures and file links plus links to subordinate article pages.

Good writing! Please let me know how I can help.

Regards,
RandyP
