TMS320F2800157: Port/Pin Conflicts Within "Software" Tab of SysConfig Tool

Tool/software:

Total CCStudio-Theia newbie here, so, sorry in advance if this is a dumb question!

I'm designing a system from scratch (not using a pre-made devkit) and used the stand-alone CCStudio to map-out my I/Os, and then created my schematic and layed-out the PCB (which is in fab right now).  CCStudio did not show any sort of pin conflicts with the signals I was mapping (I'm using the 48-pin version of the IC, not that that should matter).  I'm now I'm starting to write the software in CCStudio-Theia (started with the "Empty 48pin" example) and saw that the SysConfig tool within it had both "Software" and "Reserve Peripherals" sections, which were blank.  I figured that I could take the .syscfg file originally created by the stand-alone tool and copy it into the folder of the code project, and magically my assignments showed-up in the "Reserve Peripherals" section.  I then searched-around and found-out that "Reserve Peripherals" is for creating your own device drivers/handlers, and the "Software" area is for using the auto-generated drivers/handlers that experts wrote :-)  So I figured I'd just re-do all of the configs into "Software" and then delete them from "Reserve Peripherals". 

Well, now "Software" is showing a bunch of conflicts between various pins/ports.  For instance, in the "Analog PinMux" section it is showing conflicts on pins/ports I've mapped to GPIOs or CAN pins, but I don't see any way to tell it I don't want to use them as an analog pin. I have 10 of these sorts of errors:

Similarly there are errors in the "Other" section where I need to define the ports (TDI, TDO) being used for the JTAG connector:

In case it helps, here's the spreadsheet I'd created (alongside using the stand-alone SysConfig tool) to map-out my I/Os, as well as the .syscfg file I'm using within CCStudio:

Many thanks (in advance) for whatever help/advise you can give me.  And please (please) don't tell me that I've got an issue wherein I need to redesign my mapping and re-lay-out the PCB :-o

    Hi Jim,

    In both the "Analog PinMux" and the "Other" module, you can specify a custom pinmux usecase to indicate which pins you actually want to use. Select Use Case = Custom and then check which pins you want to use for analog and "other".

    Let me know if this resolves your issue.

    Thank you,

    Luke

    Luke:

    Many thanks for the super-quick response to this!  I was sweating bullets that I'd somehow mucked-up and the boards that are being built would be junk.
    THIS is THE answer!  No more red X's. . . only green checkmarks :-)  What a relief.

    Now I just need to figure-out to to configure the ADCs to be sampled at some convenient rate (say 100 ms) and figure-out what ISR(s) get called when the ADC reads are all completed so that I can put-in my handlers to convert the "Counts" into meaningful values (volts, `C, etc.).  Any pointers to good links on that? :-)

    Again, many thanks!! I figured it would be simple but CCStudio is far more complex (and I'm sure powerful) than Arduino's IDE :-)

    Cheers!
