DLPC900: Heart beat has stopped...

Part Number: DLPC900

Hello support,

I have a problem on our DLP product.

Currently I can't see the illumination of heart beat from DLPC900 in one of our product.

So I checked a log message from DLPC900 by using serial interface.

The log message is bellow and one error message is included.

What dose the error mean?     (ptn_seq.c (1007) >> Failed  )

<log>

  • Hello Sato-san,

    Welcome to the DLP section of the TI-E2E forums.

    I would first try reloading the default firmware.  It is in the directory where the PROM files are - typically C:\Texas Instruments-DLP\DLPR900PROM-5.0.0\DLPR900PROM-xxxx-v5.0.0\ (where xxxx is 6500 or 9000 depending on the EVM you have. 

    If it is the DLP6500 EVM there will be one *.img file and if it is a DLP9000 EVM there will be a *-master.img & a *-slave.img file.

    Put the boot jumper on and power up the EVM.  It will detect connection to the EVM, but will not be able to determine which EVM (DLP6500 vs DLP9000) is connected.  Please refer to the EVM Guide DLP LightCrafter 6500 and 9000 EVM User's Guide (Rev. D) - page 15 for the DLP6500 EVM and page 18 for the DLP9000 EVM.

    When you open the GUI, first select in the status on the left the correct EVM.  Then go to the Firmware tab and select the image file(s) for your EVM.  NOTE:  If you load the wrong file(s) it will not boot up, and you will have to repeat and load the correct file(s).

    After the file(s) load, power down the EVM and remove the boot jumper. then power the kit back up.

    Let us know if this restores proper operation.

    Hello Fizix-san,

    thanks for your advice in detail.

    I tried your suggestion and then I can see the illumination of heart beat from DLPC900.

    But in the log message, new error is appeared..

      old : ptn_seq.c (1007) >> Failed

     new: ptn_seq.c (1014) >> Failed

    Could you please let me know your opinion.

    Best regards

    Sato

    Hi Sato-Shi,

    You can ignore the print w.r.t. ptn_seq.c.  Are you able to bring up the system and able to display patterns? I suspect that your flash image doesn't have sequence (FW is not able to find the sequence)

    Are you using TI provided EVM or your own board?

    Thanks

    Hello Sachin-san,
    thanks for your reply.
    Yes, your suspection is right. I've not written our image file yet because of the worried error.
    After writing our image, it works good!
    To. Sachin-san Fizix-san,
    Thank you very much for your great support!
