SYSCONFIG: TM4C custom pin names not reflected in summary.csv

Part Number: SYSCONFIG
Other Parts Discussed in Thread: TM4C1290NCZAD

Hello,

I have a customer trying to use the updated sysconfig tool to generate the pinmux files as well as the summary.csv for schematic capture. In the function field of the summary.csv, the function field only reflects the default naming of the specific peripheral instantiation. For example an I2C0 instantiation named Power_I2C0 would look like this:

A17,PB2,I2C0SCL, , ,
B17,PB3,I2C0SDA, , ,

Where previously the function field would also reflect the name of the I2C instance. Is there a way to change the name of the function field to reflect the customer's assigned names for each peripheral instance? This would save a lot of work renaming each line manually in summary.csv.

    Hello Munan,

    Please give us some time to review your concern.

    We will get back to you this week.

    Hello Munan,

    Could you tell us for which device you are trying to generate the pinmux config?

    Regards,

    Hi Jitendra,

    The device in question is the TM4C1290NCZAD.

    Munan,

    Are you saying that in PinMux you used to see the "name" but in SysConfig you do not?

    When I run PinMux I don't see the name in the generated .csv:

    I named them TESTNAME and MyI2C2 but the .csv shows:

    Pin#, PORT IO, Function, Directions
    N15,PG0,I2C1SCL, , ,
    T14,PG1,I2C1SDA, , ,
    A17,PB2,I2C0SCL, , ,
    B17,PB3,I2C0SDA, , ,

    Regards,

    I asked Munan to help me raise this to the attention of people at TI who might make this tool more useful.  I have used the PINMUX tool and now the SYSCONFIG tool to map out the functions and IO on my microcontroller design.  To me what is lacking, and has always been lacking, is the absence of the user defined name in any of the output files.  It would seem to be an obvious field to be included in the summary.csv file.  When I am doing schematic capture, I would like to review the table of pin/function/name assignments.

    Joey,

    In the original post Munan specifically mentioned that the csv file originally had the names included but no longer does.  Was that the case?  I was trying to determine if this was a change in behaviour.  In tried both PinMux and SysConfig myself and neither had the name in the versions that I tried.

    If it was a change then we would want to track down why we changed before undoing that and potentially having some other impact.

    Regards,

    John

    Perhaps this was a miscommunication.  With respect to this specific issue, the SYSCONFIG tool works as the PINMUX tool did; the user assigned names were not reflected in any of the output files.  From my perspective, this would be a useful feature and make the tool more useful.

    Thanks Joey.  I have filed a request to add the user defined name to the generated .csv file.  https://sir.ext.ti.com/jira/browse/EXT_EP-10329

    I am not sure if there are issues with just adding it to the file (i.e. if people are expecting to parse the file in a specific way.  Anyway the team will look at that when the review the request.

    Regards,
