Hi everybody!

I'm new in the DSP world and my entire life depends of this!! i have a very big
trouble and i don't know how to fixed out...  The questions is as follows:

I have one dsk6711 and one dsk6713.  I need to transfer data between them (an
array with 128 elements) using McBSP. I'm using the following example code to do
that (please see spra455a  "Using the TMS320C6000 McBSP as a High Speed
Communication Port (Rev. A)" ). 

C6711 is master and C6713 is slave. I'm using CCStudio_v3.1 and i have a few
questions:

1- I need to make two different projects? (one for C6711 and another for C6713?)
how can i run both at the same time using Parallel Debug Manager?

2- The registers in McBSP_config and EDMA_config are ok??

3- What else i need? 

Please post code too. Thanks!

CCS software will not open 2 parallel ports or 2 USB ports at the same time.  In
your case (student newbie), the least
confusing and most likely to work method is two separate projects running on two
separate PCs.  An alternative is two
separate projects on one PC:  get one board running code, leave it running,
close CCS, disconnect cable from one DSK,
connect to other DSK, re-open CCS, open the other project, get that code
running.

A further hint:  get the first board running "wire loopback" over its
McBSP.  Then you know it's working, all you have
to do is replace the loopback plug with a short cable to the other DSK.

What do I mean about short cable?  Where to connect McBSP?  Ahh, see comments
below.

100s of students have been assigned this class project over the last few years. 
You might get more help on this group
if you show that you've searched the group archives and found the numerous other
threads talking about this same
project.  Even in the last few weeks there has been discussion with other
students that you can benefit from.

If your "life depends on this", then I would expect you to at least
show a level of effort that matches your
competitors (i.e. your fellow students).

-Jeff

<mld>
Yes, you need 2 separate projects.
You *may* be able to open 1 PPort and 1 USB CCS window under PDM [I
have only done this using a full version of CCS].
1. In CCS setup, try selecting a PPort configuration and then adding a
USB configuration.
2. Save your configuration. [NOTE: You may want to edit the name' to
6711DSK and 6713DSK before you 'save' to keep them straight]. If CCS
setup allows you to do this, export the configuration to the
'C:\CCStudio_v3.1\drivers\import' directory.  Use this configuration
every time that you bring up CCS - this will ensure a consistent
configuration each time.
3. When you bring up CCS, PDM should come up, allowing you to open
each debug window.

Well, i resolved  the first question, i did a group using the parallel
debug manager (in CCS see help-->contents-->debugging windows &
analysis tools-->parallel debug manager-->using groups with PDM+) and i
can run the two projects at the same time.

Well i decided to do it using polling instead edma.  The transmitter seems to be
ok but the reciever don't "see" any incomming data.  The connections
are:
C6713            C6711
J3 pin(3) GND--->  J3 pin(3) GND
J3 pin(21) CLKX0-> J3 pin(27) CLKR0
J3 pin(23) FSX0--> J3 pin(29) FSR0
J3 pin(24) DX0---> J3 pin(30) DR0

I can see the outdata in DXR register in the side of the transmitter but there
is no successful comunication .

I have not looked at the code, but...
Q1.  Did you install the JP1 jumper on the 6711 board to enable the
McBSP to talk to the DCard instead of the codec??
Q2. Did you program 'CPLD_MCBSP0_MUX' to enable the McBSP to talk to the
DCard??

Look at what they told me when I had a troulble with 6416. Hopefully, this

can help.
furhter more, I believe you can try the loop back mode to test 6713 to 
make sure both Tx and Rx are working ok.
Please let me know if you need the code to test 6713 (I did try this and 
it worked ok. From there you can modify based on your application)
You also can find this exmaple code under .......6713\BIOS or something 
like that when install the CCS.

Good luck!.

Many of the daughtercard signals on the daughtercard connectors are routed 
through buffers to enable them.  This can be done by shorting the DC_DET 
pin (pin 75) on the Peripheral connector to ground.
 
Your findings might be a result of the software application you are using. 
 Texas Instruments might be able to help you determine if this is the 
case.

<mld>
I have not looked at the code, but...
Q1. Did you install the JP1 jumper on the 6711 board to enable the
McBSP to talk to the DCard instead of the codec??
Q2. Did you program 'CPLD_MCBSP0_MUX' to enable the McBSP to talk to the 
DCard??

Thanks to everybody for this fast response.  Well, i tried to put together both
codes, transmmitter and reciever in digital loop back mode (only changing to
MCBSP_SPCR_DLB_ON and MCBSP_PCR_FSRM_INTERNAL), and i tested in both boards and
it seems to work without failures  (in ccs the dxr and drr mcbsp registers have
the same values and both buffers outbuffer and inbuffer are exactly the same) so
i think is a hardware trouble, but anyway, Tung, maybe will be useful to have
the code to test it ... i will appreciate it.

Mike... about the JP1 jumper and the 'CPLD_MCBSP0_MUX'... i don't have any idea
what your talking about jaja but please, could you explain me in detail because
i believe that will help me a lot, thanks!!

<mld>
The McBSP can be connected to the 'on board codec' OR the daughtercard.
The 6711 DSK has a physical jumper, JP1. Refer to the schematics -
look on sheet 1 for "daughtercard peripheral connect".
The 6713 DSK uses a software switch to do the same function. Refer to
the schematics - somewhere around page 13/15.  Also look in the tech
ref manual - do a search for CPLD_MCBSP0_MUX'.

Thank you Mike!! i'm very happy because the communication "it's alive"
jeje what i did was, in the C6711 use the McBSP1 port because it's always
available and in the C6713 i use the McBSP0 and i wrote the lines for the CPLD:

#define DSK_MISC_REG (*(volatile unsigned char *)(0x90080006)) in the header
and
DSK_MISC_REG |= 1;
in main,  The communication it's not perfect yet because the first 200-250
elements are always  lose but it's a start.  Maybe i could use the EDMA
controller or something instead polling.

Lesson learned:
    Understand your hardware.  It makes it easier to write software.

Mike's steps for successful I/O on unfamiliar hardware:
1. [crawl] Play with the port. Read and write some registers to make
sure that you understand the hardware. complete.
2. [walk] Write standalone polling code to make it work. complete [almost].
3. [run] Write standalone EDMA code to make it work.
4. [integrate] Integrate the working I/O into the application.
