Serial flash utility - OMAP L137

S P Vani
Prodigy 40 points
Other Parts Discussed in Thread: OMAP-L137

Hello,

We are using the Serial FLash Utility (sfh_OMAP-L137.exe) to flash the images (DSP UBL & ARM bin images) for OMAP-L137 processor.

We are creating batch files to call this executable and port the parameters to it. But the executable fails (displays unhandled exception) when the standard output is redirected to a file to log the status.

We need to call this executable from LabVIEW software application and display the status in it.

Request anyone to help us out in this regard.

Regards,

Vani

    Hi Vani,

    Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages. Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics.

    The serial falsher utility will behave and work as a normal .exe provided all the required parameters are passed with correct format/syntax.

    Not sure how the parameters are passed to the utility through batch file. What are all the parameters ( commands and Options) used?

    Please post the logs with error messages as well.

     

    Regards,

    Shankari

    Hello Shankari,

    Thanks for the reply.

    The batch file executes perfectly without any issue. But we would like to redirect the stdout to a file. We are unable to do that.

    Batch file:-

    @ ECHO OFF

    sfh_OMAP-L137 -erase -p COM1 -baud 115200 > result.txt

    Below is the output when redirected to a file:-

    Hello Shankari,

    I have pasted the console output after successful completion of "ERASE" operation. We want the below to be redirected to a file (.txt).

    Hi vani,

    Yes. In windows, while re-directing the output to a file, it gives a handle error.

    But I don't think, this particular requirement was considered while developing the serial flasher utility.

    You can customize the serial flasher utility according to your needs.

    The source code of the serial flasher utility is available at http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L137

    and the steps to rebuild the utility is also given at http://processors.wiki.ti.com/index.php/Rebuilding_the_Flash_and_Boot_Utils_Package

     

    Regards,

    Shankari

    Hi Vani,

    Try modifying the sfh_ais.cs source file (found at <install dir>\Common\sfh\sfh_ais.cs) . Specifically, search for the function called 'DisplayProgressBar', which is called several times in that file. It appears that displaying the progress bar is what is causing your redirect-to-text issues.

    After you make your modifications you will need to rebuild the tool. Let us know if this solution works for you.

    Thanks,

    Clinton

    Thank you Shankari & Clinton,

    I have looked into the source file "sfh_ais.cs" and will modify as you suggested.

    I will update both of you once finished.

    Thanks once again.

    Regards,

    Vani
