MCSDK demo program failure

Other Parts Discussed in Thread: SYSBIOS

Hi,

    I'm running the two demo programs shipped with EVMC6678L board. Both demos start out fine because I can access the http main page(192.168.2.100 in my case) on a PC connected to the board.

    But after I did some operations . the demo programs stopped working.

    Here's the *operation* I did. For the HUA demo,I benchmarked the throughput using 100Mb data. After that,I can't access the main page of HUA. For the image processing demo, after I processed several images, I can still access the main page,but when I pressed *process* button on the page, the result page didn't show as expected.

    I have occasionally seen similar behavior, though I'm not sure why.  What browser are you using?  Have you tried multiple browsers?  Be sure to use the "back" button built into the page not the browser back button.  That has given me problems in the past.

            I'm using an IE browser to access the board. This time I used the "back " button build into the page, but the problem remained the same.  However, an error message was shown in the output window of CCS after I can't connect to the board. It said:

    ********************************************************************

    ti.sysbios.knl.Task :line 894:assertion failure:A_badpriority An invalid task priority was used

    ti.sysbios.knl.Task :line 330:E_stackoverflow:Task 0x814a7f88 stack overflow

    xdc.runtime.Error.raise:terminating execution

    ************************************************************************

           what's strange is, when the HUA program was working properly, I checked the task list ,there's no task ID 0x814a7f88. So the task must be generated after my check and before the demo failure.

    I've had better luck with Firefox than IE.  Another thing, did you update your MCSDK or are you using the one from the CD?  Please try  the latest:


    http://software-dl.ti.com/sdoemb/sdoemb_public_sw/bios_mcsdk/latest/index_FDS.html

     

    There is a patch release v2.0.3 happening today, so I would wait to download until tomorrow.

    Hi Travis,

           Sorry for taking too long, I try the demo programs again using MCSDK2.0.3 and firefox. But the not-answering problem remains. I think there is something wrong with the NDK software because I encountered similar problems when doing NDK benchmarks on a C6747 evm board. I can only test the network speed for a limited times then the stack crashes.

          Any further suggestions? Thanks.

    Roy,

     

    I will forward internally and see if others have suggestions.

    Roy,

    Which version of the NDK are you using?

    Can you open the ROV tool to get us some more information?  ROV is found under the menu "tools->ROV" within CCS (4 and 5).

    Once ROV is open, you can have a look at the tasks that exist in the system.  It will tell you things such as stack sizes and if there was an overflow or not.

    Thanks,

    Steve

    Steve and Travis,

           NDK version 2.20.4.26 is used on 6678L board and version 2.0.0 on 6747 board.

           I tried to use the ROV tool to check stack sizes, but an issue occurred and ROV failed to start. I did select every component I needed in the project's ccs_build/RTSC tab. Then I created a new template project and tested ROV in debug mode. It worked fine. So I think there's something wrong in the HUA demo project configurations that causes ROV's failure. But I don't know where it goes wrong. Any suggestions?

     

    Thanks

    Can you please post a screen shot of the ROV error?

    Thanks,
