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 :- ) Hwanhee ------------- 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.

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 :-) Al --- In , "ftts8204" <ftts8204@y...> wrote: > > > 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.

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 -----Ursprgliche Nachricht----- Von: ftts8204 [mailto:] Gesendet: Dienstag, 16.

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.... any thoughts?

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.N.Iyer _________________________________________________________________ NRIs!

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! --Bhooshan ----Original Message Follows---- From: Tarang Dadia <> Reply-To: Tarang Dadia <> To: Bhooshan iyer <> CC: Subject: Re: [c6x] C6711 DSK POST Problems( Similar to the C6713 thread) Date: Fri, 19 Nov 2004 09:59:32 -0800 Bhooshan, I have had similar observation after I tried 'programming the flash' example on the DSK.
