C6713DSK Target Communication Error, similar to Andreas' C6416DSK

Started by ftts8204 November 16, 2004


Hi,

I am using the C6713 DSK and have been stuck with exactly the same
problem for the past week -- hence almost no work done. Frantic
search on discussion groups took me here and I feel a little better
now that at least it is not my complete fault to burn out the DSK :-
)

Andreas, are you able to reset the emulator through CCS--> Debug -->
Reset emulator? When I tried, my board was succesfully disconnected
from CCS, but when I click on "reconnect," I get the error message:

CPU_1 - DSP Device Driver

Can't initialize Target CPU:
Error 0x00000200/-536866794
Error During: OCS,
Unknown Error

I/O port = 540

Board Name: C6713DSK
Cpu Name: CPU_1

Are you experiencing similar problems? Any idea on what I should do?

Tarang, I checked if I was doing what you said I should not be
doing, but in most cases, I see the communication error message 20
seconds after I start CCS -- basically I am forced to power cycle
the board over and over again just to load CCS without being able to
work on my project -- do you have any idea why this is happening?

Thank you both. I am a student in my final year and this is the
first time I am programming a DSP. Any help is greatly appreciated :-

Andreas: THANKS for your email. I have just read your reply but I
thought maybe I should post my original message again so Tarang can
read it too :-) I haven't tried contacting TI or SpectrumDigital....
I browsed through their websites but there was little information
available, given that TI directs all problems to www.ti.com, I made
the conclusion that they probabaly don't provide good customer
services...... I also have difficulties logging into the TI site...
*sigh* ... As for user caused damage, I haven't tried connecting a
daughter card to the DSK... Which daughter card did you use?

This is the only board I have at the moment so I really am
frustrated about what to do.... Definitely hope I could get the
board up and running sometime soon....

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

Here is Andreas' email reply to my post above, hope it could benefit
anybody who's facing similar problems..... Hi Hwanhee!

Your last message has been only sent to me, you should use he "reply
to all" function in your mail client to send a copy also to the
mailing list(so Tarang can also read it).

I also tried to use your suggested way to disconnect/reconnect the
board -->> same error like you :-( I think that this is
an "followup" error,because if CCS looses connection once it seems
that there is no possibility to tell the board anything. The
disconnect could mean that CSS only stops trying to communicate with
the target. Even the diagnostic utility is sometimes not able to
complete the "reset DSK" or "reset emulator" commands --> "can't
connect to target" on USB-diagnostic. I highlight the "sometimes",
because sometimes it works, sometimes not!

Have you asked TI or SpectrumDigital about this issue? I wrote a
mail to TI support about another problem I had, but they answered I
should ask my prof and he could contact the support - if he joins
their university programme :-) ,so no help on this from that side
(I'm also a student working on my diploma thesis). Perhaps
SpectrumDigital has a solution ?!

Today the board worked till midday, the whole afternoon not. But
fortunately we have some other boards of the same type, so tomorrow
I will try to get my installed software work with a new one. I hope
that will reveal if it is really a hardware or a driver/software
problem. But actually I'm a little bit afraid of doing this, because
if the fault causes in a mistake of my part I may damage the other
board also :-(

Some things I've done with the DSK so far, perhaps you did something
similar and it is really a user caused damage:

-Bridged DC_DET to GND to enable daughtercard interface -Connected an
external chip to the external memory interface (to use it as an
parallel input; signals are 5V-TTL, but this should be no problem
because of the two buffer chips between the pin header and DSP)
-Enabled EDMA channel to copy the data from EMIF to SDRAM (event-
triggered by EXTINT6) -Some operation on the accquired data

Funnily enough all these things work... When I get the board to work
:-)

Hope we'll get this fixed...

Bye

Andreas




Hwanhee,

Thanks for posting it and keeping me in the loop.

The things that I mentioned were just the definately-do-not-do
things... but I know there are other instances when I have experienced
the similar behaviour and I was not able to go to the root. I have
experienced that even if there were no operations being performed on
the DSP and DSP was sitting idle, it would sometime think of not
working and wud throw JTAG communication error.

Just was curious do you have robust connection from PC to the DSK
board?? by that I mean does the male to female connection bond
together well.?? I know it is basic thing but just b sure.

Hope this helps
Tarang

To 6713 DSK users with trouble You're not alone with DSK problems! The company I'm working for has
4 of the Spectrum Digital 6713 DSK boards. We have had nothing but
trouble with them connecting to CCS with the PC. The first time I had
trouble was on a warm day last spring. As time went on it stopped
talking to my laptop and then to my PC. All of my other USB stuff
still works fine on my machines.

You'll laugh but if I put it in the refrigerator with the USB
and power cables coming out the door it would run. It went back to
Spectrum Digital and in 2 weeks came back and worked for 4 days before
doing the same thing again. Back to Spectrum Digital it went for
almost a month only to be returned having the same problem. Another
guy at work used it on a different PC with the same problems. We both
swapped them out. A second unit I have now also flakes out on me from
time to time as well as having a glitch on the /WR line of the EMIF
connector when the SDRAM on the DSK is refreshed. The glitch was 15ns
long, VERY hard to find, and was trashing registers on my daughter
board.

I've talked with Spectrum Digital tech support several times
and one guy said they had a batch of bad chips and that they have
changed the design somehow. I couldn't get him to tell me the
changes and our boards are out of warranty now.

The DSP section of the board seems to work fine all of the time, if
I can flash my code into it, so maybe it's time to use an emulator
from another vendor and the full CCS so I can bypass the built in
emulator.

If only things could be easy :-)

Hi!

I tried a new board yesterday and today and it seems to work! Did the same
operations and
connections as before and until now I got no error. Hope that remains
constant and it will not decide to worry me again ;-)
Nevertheless I will try to contact SpectrumDigital, perhaps they already
know about this issue, and I'm really interested in why the other board had
that problems.

@Hwanhee: I do not use a "real" daughtercard. I'm using another development
board for a programmable downconverter that provides two 16-bit outputs for
I and Q data, and because I couldn't find a normal paralell input on the
DSK, so I "misuse" the external memory interface for that - I connected the
ouput of the PDC to the [0:31]data pins of the board and reduced the entry
in the memory map area of the GEL file in CCS to only one readonly 32bit
address (from 0xA0000000 to 0xA0000004). So I can access the incoming data
by reading on 0xA0000000 (or copying the data to memory via EDMA).

Keep me up-to-date about your progress to get the board run. If I get a
reply from SprectrumDigital I will post it.

Bye...

Andreas, are you able to reset the emulator through CCS--> Debug -->

Your last message has been only sent to me, you should use he "reply

I also tried to use your suggested way to disconnect/reconnect the

an "followup" error,because if CCS looses connection once it seems
that there is no possibility to tell the board anything. The
disconnect could mean that CSS only stops trying to communicate with
the target. Even the diagnostic utility is sometimes not able to
complete the "reset DSK" or "reset emulator" commands --> "can't

because sometimes it works, sometimes not!

Have you asked TI or SpectrumDigital about this issue? I wrote a
mail to TI support about another problem I had, but they answered I
should ask my prof and he could contact the support - if he joins
their university programme :-) ,so no help on this from that side

that will reveal if it is really a hardware or a driver/software

if the fault causes in a mistake of my part I may damage the other
board also :-(

Some things I've done with the DSK so far, perhaps you did something
similar and it is really a user caused damage:

-Bridged DC_DET to GND to enable daughtercard interface -Connected an
external chip to the external memory interface (to use it as an

-Enabled EDMA channel to copy the data from EMIF to SDRAM (event- triggered

Funnily enough all these things work... When I get the board to work
:-)

Hope we'll get this fixed...

To those that replied to my previous messages and other 6713 DSK
users with trouble.... Here is the answer I got from my post on the google dsp group:

-----------------------
One possibility is that you tried to burn the flash memory with a
new image and failed. It this case the DSP could run into a state
where CCS can't access it. It can be other reasons as well. Try to
press the reset button on the DSK and then quickly click on retry,
this usually solves the problem.

--
Lars Ljung
-----------------------

Indeed before the CCS starting to lose connection to the DSK, I was
experimenting with the FlashBurn Utility Tutorial! I tried 'reset'
then 'retry', but it doesn't seem to be working....

I only understand a small portion of the instruction given... maybe
someone else facing the same problem can try this out? Hwanhee

Hi All-
Thought i will add to the list of woes...

Lots of our C6711 boards donot pass the POST tests very well atall
particularly after a few months of usage.

I.e the LED counting from 0 to 7 just doesnt happen ( not in a timely way
anyway), they are either stuck at counting two or three. But the CCS window
powers up(and on power up, the LED"S do blink thrice!) regardless and we
are able to download and debug projects.

My doubt is, if we were to take these LED *freezes* as failures "to read the
SDRAM" or failures of "CODEC output tone tests", then one shouldnt not
expect any sort of normal behaviours in any of our audio programs. But the
experience is that despite the fact that they fail these tests the programs
work just fine.

What could be the reason? is it a case where the LED has konked??? (this
cannot happen to all our boards where we have had similar experiences??) or
is the POST program full of bugs/false alarms? Iam more inclined towards the
second possibility beacuse when i run some (free) third party diagnostic
tools like WinDSK , the DSK's pass all the above tests and even posts very
good SDRAM access speeds.

Any thoughts? Anybody with similar problems?

Bhooshan,

I have had similar observation after I tried 'programming the flash'
example on the DSK. Have u reprogrammed ur flash? In my case the LED
will keep on blinking till ever forever.

Also somewhere else I had read that LED are just used to indicate that
all the POST have passed. I dont think they are attached to some SDRAM
test or codec tests.

Tarang-
>Have u reprogrammed ur flash?

Not all the DSK's that behaved had been flashed.So am not sure about that
conclusion.

>Also somewhere else I had read that LED are just used to indicate that
>all the POST have passed. I dont think they are attached to some SDRAM
>test or codec tests

POST stands for Power On Self Test. The tests it conducts are indicated as
follows:

Test LED 3 LED 2 LED 1 Description
0 0 0 0 Start state
1 0 0 1 DSP internal SRAM test
2 0 1 0 External SDRAM test
3 0 1 1 DSP McBSP0 loop back test
4 1 0 0 External codec read/write test
5 1 0 1 External codec tone generation test
6 1 1 0 External LED and DSP timer test
7 1 1 1 Unused available for future test use

B L I N K A L L All tests completed successfully Thats why i feel this POST program is quite buggy and alarmist!
