Testing External Memory

There is an app note on the Power-On Self Test which comes burned into the C6713/C6416 DSKs. This tests many of the features on the board including the external memory.

You will definitely need to program the EMIF before attempting to communicate with the memory. Once configured, the test could be something as simple as a pointer.

I'm reading the docs on setting up the EMIF and the PLL's etc. Is there a document somewhere that shows what all needs to be done to get the chip up and running. Also is there any example code for the Pll's, EMIF, etc?

If you have the DS6713 Board Support package (it comes on a CD with the DSK) you should actually already have a POST project. By default it would be in the \examples\dsk6713\bsl\post folder.

Additionally you can find some PLL/EMIF configuration code in the GEL file (\cc\gel folder).

Thanks, I did not see the post folder, I have been in the tutorials, not the examples.

I tried to build the post example and it failed. The output is below, any ideas?

Sure, this should be an easy one :)

All of these symbols are part of the Chip Support Library. BIOS 4.90.xx actually included CSL support inside the GUI. This was dropped in BIOS 5.xx due to a number of problems (both functional and scalable) so you need to add it manually to your project. To do this simply add the csl6713.lib to your project (\c6000\csl\lib).

Thanks, I added the csldm713.lib and now it works. I'm looking through the code and trying to see where the EMIF and PLL's are set up. There is a call to "DSK6713_init" and I see that in the .h file but I can;t find the source for it. Is this where the setup occurs, or is it done in the post.tcf file?

A note in the code says to see the "6713 DSK help file under Software/Examples" where can I find the help file? The CCS help file has a doc on the tutorials, but not the examples.

This is DSK BSL stuff. It all comes in the Board Support Package provided from Spectrum Digital. This should have been part of the install that comes on the CD you get with the DSK.

I finally found the help file, but it is not any help. It just has a very brief description of what the program does. It has no details at all. I'm still trying tofigure out how the EMIF and PLL's get set up.

Thanks, that is what I'm looking for.

How do I get output to stdout?

I have #include <stdio.h>

and in

main()
{
//    puts("post example started\n");
    printf("post example started\n");
    DSK6713_init();
    /* Set initial LED state */

...

but neither puts or printf seems to work. Is there something else I need to setup?

I'm looking at the hello1 tutorial and I don't see them doing anything else.

Thanks

Make sure that you have included the RTS library and that your stack and heap sizes are sufficiently large. If not using DSP/BIOS you can configure stack/heap either in the Project->Build Options or inside the linker command file.

If I add rts6700.lib to the project I get

I tried searching for c_int00 to see if I could tell where it was duplicated but it is not in source code.

Any ideas?

Searching for 'c_int00'...

c_int00 is included in the RTS. If you are getting multiple definition errors you probably have the RTS included elsewhere. Check the build options or the command file for something like "-l rts6700.lib"

The postcfg.cmd file has -lrts6700.lib in it so I'm assuming that is the duplicate def problem.

As far as the stdout not working, I'm using dsp/bios and looking at the mem options. The Stack size (MAUUs) is set to 0x0400 and "No dynamic Heaps"  is checked. Is this correct? what should the settings be?

Thanks

You will need a Dynamic Heap.  Please uncheck the "No dynamic Heap" option in the MEM - Memory Section Manager Properties.
You will then need to highlight a memory region, such as SDRAM and open its properties.
Check "create a heap in this memory" and click OK.
Go back to MEM - Memory Section Memory Properties and choose SDRAM for "Segment For malloc() / free()" and for "Segment For DSP/BIOS Objects" and click OK.

EDIT : added choose SDRAM for "Segment For DSP/BIOS Objects" requirement.
