Hi,

When we enable watchdog timer, after 175 hours (approx) we are facing file system crash (Kernel is booting up, but rcScripts & /opt/bin/binaries are not executed). Earlier we thought the issue was something with application modules and re-designed application modules. But this time i am very sure, the issue started after enabling Watchdog timer last week.

 

Work environment:

TI DaVinci processor (TMS320 DM355)  

Monta Vista Kernel (ported to busybox)

 

Doubts:

·         Do we need to add any extra hardware for enabling Watchdog timer? If so how it is working fine for 7 days (~175 hours)

·         I have copied ti watchdog file below (I have added davinci_wdt_enable() function call in wdt_init function), please look into it and let me know if i have to change any other parameters please

    Dear Santha,

    as for my knowledge so far there are no specific known issues in relation to DM355 and the watchdog functionality

     

    also, I am not sure why you would need to modify the driver as it seems that watchdog is already supported within the released driver package

     

    I saw you are using DVSDK 1.30 - as a side comment the DVSDK 2.x watchdog driver has a radically different structure, but it seems that DM355 watchdog is not supported "as is" within the driver

     

    The latest driver as for the comments and datasheet is tested for DM644x / DM646x devices, so some porting might be needed - the latest DVSDK file source is different than the one you attached, but it might serve as a further check.

    You can find the DVSDK 2.x here:

    http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_2_00/latest/index_FDS.html

     

    Not sure whether how much Linux would suffer from such kind of reset, perhaps not so much as long as you don't write to the filesystem. However I would recommend giving it a try by using the standard evm released LSP. Maybe try to run the demo first, automatically when the device starts. Then add the watchdog with a reasonably long timeout without pinging it, so that it will time-out at some point and the board would reset. It should allow you to check if there is something wrong with the startup sequence after having got a watchdog reset vs. a hard reset or a sw reboot

     

    Some more comments on the functions you attached:

    - as for my understanding davinci_wdt_open will include already WDT enable - thus you are enabling the watchdog twice in the code - not sure you might want to do it this way

    - the wdt write function would take 4 parameters, actually, if I did not miss something

    - in the logs I noticed the following:

     

    yaffs: dev is 32505859 name is "mtdblock3"

    yaffs: Attempting MTD mount on 31.3, "mtdblock3"

    block 74 is bad

     

    maybe you want to check what is there within the flash block, to make sure there are no issues with the flash device - I guess you stored a different image after rebuilding the kernel.

    Maybe using an NFS mount could be an alternative to test, as you are using the flash based file system, seen from the logs. Make sure you have a consistent kernel image and file system before you rebuild, so that you don't get kernel or module mismatches

    Dear Giancarlo,

     

    Thanks for your quick and detailed response for my query. I will do the necessary modifications as you suggested and then will let you know the status.

    Once again thanks for your response.

     

    Best Regards,

    Hi all,

    I'm working with DM355EVM , a dvsdk 2.00.00.22 , gst-dmai 1.01.00 , LSP / PSP 2.00.00.140, MV toolchain 5.0, NFS. I followed this procedure:
    http://wiki.davincidsp.com/index.php/DMAI_GStreamer_Plug-In_Getting_Started_Guide#DM355_software_installation_.28DVSDK_2.00.00.22.29.

    I need to automatically reboot the system when it crashes.

    I found that watchdog can solve my issue, but I don't understand how it works. I see that it has a timer on /arch/arm/mach-davinci/timer.c that is compiles (there is the timer.o ) file.

    I searched in the SDK, but I don't find anything (I think that it's already included).

    1) Is it right?

    2) How can I manage the watchdog and its timer?

    3) How can I test if it works?

    Thank you for your attention.

     

    Best regards

    Lorenzo
