Problem with update

Other Parts Discussed in Thread: SYSBIOS

Hello everybody,


I have a problem generated by updates.

In fact, I had created a little program of booting which was a mix of a traditionnal boot and a simple ethercat programm that implement fsoe for downloading and flashing a new code in my dsp. I work on a sitara arm3359.

I had created this program a long time ago: I have used sdk 1.1.0.4 + xdctools 3.25.5.94 + sys/bios 6.33.5.46. This program was a success !

Now, I want to update my software whith the last souces: sdk 1.1.0.8 + xdctools 3.30.6.67_core + sys/bios 6.41.4.54. I have made all the necessary modifications in all the files. When I launch this program in DEBUG everything is all right. Then I create the good .bin and i flash it at the bootloader place.... But nothing work ! I tried to see what happens using a uart debug but what i see is that the program does not start at all !!! I have checked the .bin generated, the memory flashing... everything seems correct !

Is anyone have an idea ? I think it's a problem due to xdctools and sysbios but i don't know what...

Tha nks a lot for your help

Laurence

    Hi,

    From what I understand, you have a new bootloader here. Is the bootloader starting alright? if yes, is the control transferred to the application entry point correctly?

    Hello,

    In fact my problem is that my custom bootloader (which is a mix between the traditional boot + an simple ethercat application that implements ethercat) doesn't start at all when i load it in the sitara flash.

    When I debug it in RAM there's no problem but whan i make a .bin and flash into the sitara memory nothing starts (at the beginning of the main, the bootloader writes on the uart and i don't see anything).

    Regards,

    Laurence

    Hello Vinesh,

    I can give you some details to help you to undesrtand my problem.

    In fact my custombootloader is a mix between the traditionnal boot program and the ethercat program provided by texas.

    This custom bootloader was working good with the sysbios 6.33.5.46 + xdctools 3.25.5.94.

    I wanted to make the good upadte: sysbios 6.41.4.54 + xdctools 3.60.6.67_core.

    I made all the necessary updates.

    Then  I try my program in DEBUG: OK.

    Then I try to flash this bootloader: NOK.

    Thanks to my serial uart, I managed to focus on the function that put problem:  "tsk1 = Task_create (task1, &taskParams, NULL)".

    This function seems to reset evrything !!!!

    I also made the foolowing verification : the traditionnal boot program and the ethercat apllication program are OK with this sysbios.

    Do you have an idea to solve my problem ?

    Thanks a lot

    Laurence,

    We have seen that while updating the SYS/Bios versions, usually the binary size grows(text, data etc.). The issue here could be that the Bootloader/app placement in the flash is overlapping? You can verify these by comparing the map files of the bootloader and app.

    Regards,
    Vinesh

    Hello Vanesh,

    I had already noticed that the size were growing but everything seems all riht in my map file (no overlap).

    I wiil send you the map file tomorrow (I'm out of my office today) but i don't think my problem is a mapping problem.

    Do you have any other ideea ?

    Regards,

    Laurence

    Hello Vanesh,

     

    I send you my map file to verify that there's no overlapping problem in my bootloader.

    Do you have any other idea that makes the function Task_create never ending ?

    Regards,

    Hi Laurence,

    Did you do a comparison on the map files of working/non-working application?

    Of course I did it !
    And what I saw is that the function "ti_sysbios_knl_Task_create" that refers to the Task_create function does not exist in the working project. In fact, the two librairies are completely different but I don't think that it is my problem...
    To summarize my situation: when I call the function Task_create nothing work in my project; the uart log, even the ones before the call to the function, don't appear... But if I comment the call to this function, everything is all right....
    An idea ?

    Thanks a lot,

    Laurence

    That's weird. Seems the issue is with Task_create not defined in the binary. Will have to loop in CCS/SYSBios experts for help.

    Vinesh,

    In fact it seems to be a size issue as you said first. Instead of creating task1 (which is the task of ethercat that created PDITask and Sync0Task) i have created a task that do noting (sjut a while instead) and then the program functions !
    So I think that there's a problem of overlapping but I don't know where.
    So I try to look into the map file and see the adress where are stocked somme function. First I searched the first function called in the main program of boot : "BlPlatformConfig" and I can't find this function in the map file. Even in the map file of a well working function. ... I don't undersatnd how the map file function: I can find some functions but not ALL the function of my program !!!
    Can you explain me how it is possible ?
    Or do you have a documentation on that ?
    Do you have any idea to point out my size proble ?

    Thanks

    Your issue has been sent for investigation by the SYS/BIOS team. However there are holidays now in the USA and most people are on vacation. Response may be delayed after Monday.

    Hello Vinesh,

    As I said you in my last post I think that there is un problem in my mapping but I don't know what is the problem.

    I have already send you my map file: can you have a look at it to see if you can find a problem ?

    Thanks a lot.

    Regards,

    Laurence

    Hi Vinesh,

    Sorry for the delayed response.

    I looked at your .map file and it seems like the Task_create function is being pulled in from the ethercat_pea8fnv library rather than the sysbios library (line 471 of the map file). Can you please post a screen shot of the linker libraries in your project? Additionally, can you post the link line that is on the console when you compile the project?

    Thanks,
