HalCoGen 3.04 can't change SPI baudrate

Other Parts Discussed in Thread: HALCOGEN

I am trying to set up mibSPI baud rate in  HalCoGen  3.04 release and the tool doen't allow me to do that. To verify it I made a project in previous version  HalCoGen  3.03. It is changing prescale as soon as I type it in. The same project loaded in  HalCoGen  3.04 is frizzing the prescaler.  Is there any trick?

    Dmitri,

     Our Halcogen SME will look into this and get back to you.

    I checked on another computer with HalcoGen 3.04 it doesn't work for MibSPI1,3,5 only. SPI2,4 are Ok. MibSPI1,3,5 delays don't work as well.

    Hi Dmitri

    Sorry for the incovinence.
    MibSPI1,3,5 prescale values calculations are broke due to the minor bug while adding SPI1, SPI3, SPI5 ( which are compatible mode of MibSPI1,3,5 ) to version 3.04 from 3.03.

    We will fix this and do a patch release as soon as possible.

    Meanwhile, I have two quick workarounds you can pick any one.

    Workaround 1)

    - ONLY follow this If you are not using SPI1, SPI3, SPI5, go to C:\ti\Hercules\HALCoGen\v03.04.00\config\device.xml. Remove

    <TMS570LS3137ZWT>  ( Which ever family of device you choose for code generation ) 
    ---
    ---
     <SPI1>TMS570LS3137ZWT/SPI1v000.xml</SPI1>
     <SPI3>TMS570LS3137ZWT/SPI3v000.xml</SPI3>
     <SPI5>TMS570LS3137ZWT/SPI5v000.xml</SPI5> 
    ---
    ---
    </TMS570LS3137ZWT>

    Workaround 2)

    - Got to C:\ti\Hercules\HALCoGen\v03.04.00\drivers\TMS570LS3137ZWT\
    - Edit SPI1v000.xml..  Search for following and rename

        calcSpiPrescale1 -->     calcSpiPrescale1_spi1
        calcC2TDELAY1  -->   calcC2TDELAY1_spi1
        calcT2CDELAY1  -->   calcT2CDELAY1_spi1
        calcC2EDELAY1  -->   calcC2EDELAY1_spi1
        calcT2EDELAY1  -->   calcT2EDELAY1_spi1

    - Edit SPI2v000.xml.  Search for following and rename

        calcSpiPrescale1 -->     calcSpiPrescale1_spi2
        calcC2TDELAY1  -->   calcC2TDELAY1_spi2
        calcT2CDELAY1  -->   calcT2CDELAY1_spi2
        calcC2EDELAY1  -->   calcC2EDELAY1_spi2
        calcT2EDELAY1  -->   calcT2EDELAY1_spi2

     - Edit SPI3v000.xml.  Search for following and rename

        calcSpiPrescale1 -->     calcSpiPrescale1_spi3
        calcC2TDELAY1  -->   calcC2TDELAY1_spi3
        calcT2CDELAY1  -->   calcT2CDELAY1_spi3
        calcC2EDELAY1  -->   calcC2EDELAY1_spi3
        calcT2EDELAY1  -->   calcT2EDELAY1_spi3

    Hi Prathap,

    Yes it works.  Thanks. The only thing I found your Workaround 2 should look like this:

    - Got to C:\ti\Hercules\HALCoGen\v03.04.00\drivers\TMS570LS3137ZWT\
    - Edit SPI1v000.xml.  Search for following and rename

        calcSpiPrescale1 -->     calcSpiPrescale1_spi1
        calcC2TDELAY1  -->   calcC2TDELAY1_spi1
        calcT2CDELAY1  -->   calcT2CDELAY1_spi1
        calcC2EDELAY1  -->   calcC2EDELAY1_spi1
        calcT2EDELAY1  -->   calcT2EDELAY1_spi1

    - Edit SPI3v000.xml.  Search for following and rename

        calcSpiPrescale3 -->     calcSpiPrescale3_spi3
        calcC2TDELAY3  -->   calcC2TDELAY3_spi3
        calcT2CDELAY3  -->   calcT2CDELAY3_spi3
        calcC2EDELAY3  -->   calcC2EDELAY3_spi3
        calcT2EDELAY3  -->   calcT2EDELAY3_spi3

     - Edit SPI5v000.xml.  Search for following and rename

        calcSpiPrescale5 -->     calcSpiPrescale5_spi5
        calcC2TDELAY5  -->   calcC2TDELAY5_spi5
        calcT2CDELAY5  -->   calcT2CDELAY5_spi5
        calcC2EDELAY5  -->   calcC2EDELAY5_spi5
        calcT2EDELAY5  -->   calcT2EDELAY5_spi5
