How to determine ROM revisions without code composer studio

Other Parts Discussed in Thread: OMAP-L138

How do you know the ROM revision of the OMAP-L138 without using the code composer studio?

We are using an OMAPL138A as printed on the board.

    The Device and Development-Support Tool Nomenclature (Section 7.1.2) of the OMAP-L138 datasheet contains information on how to parse the device nomenclature.

    Hi Christina,

    So how do you relate the Silicon Revision to that of the ROM version?

    In AISgen you have a selection of d800k002, d800k004, d800k006 while in the nomenclature you have silicon revisions 1.0, 1.1, and 2.0.

    Does this mean that d800k002 is 1.0 and so on?

    Grant,

    There is not a perfect correlation between ROM version and silicon version. The only way to determine the ROM version is to read the version character string at the beginning of the ROM, 0xFFFD0000, starting at offset 0x08. You may either read this using CCS when you have an emulator connected, or your program can read this and decode the character string for use in your application.

    Why do wish to avoid CCS for this?

    we are still ordering an emulator to connect to the OMAP-L138.

    Once we get one then I have no issues using the CCS.

     

    By the way, in the wiki (http://processors.wiki.ti.com/index.php/How_to_connect_to_the_OMAP-L138/C6748_EVM_board_using_CCS%3F) it indicated that I can use XDS100v2 to connect to the the ARM + DSP of the OMAP-L138. However Spectrum Digital's emulator comparison chart (att1145.Emulator_Comparison.pdfached) indicated that it cannot connect to an OMAP.

    Which is valid?

    What were you looking for in your original posting?

    Your new question on XDS100v2 compatibility should either be posted to the Code Composer forum or should be asked of Spectrum Digital. The TI Wiki Page that you referenced was pretty clear, but so was the SD page.

    I recommend you send an email to SD Support. You can do that through their website. They will know the latest status for their products.

    Hi Randy, our main objective is to generate a new AIS file for our custom board. Now to use the AISgen tool from TI I need to specify the device type of the OMAP-L138 on our board.

    I will raise CCS question in the Code Composer forum.
