    Hi Gautam,

    I have already consult these documents buy I haven´t seen any reference to the LEDs I am talking about.

    The LEDs I am saying are which are next to the encoder connector.

    Regards,

    Alberto

    Hi,

    Cross-referencing the HVMTRPFCKIT's schematics with the controlCARD, you'll see that these LEDs are tied to DIMM pins 31 and 32. 

    For the F28035 controlCARD, these DIMM pins connect to GPIO42 and GPIO44 on the F28035 controlCARD.  You can then refer to the code to see what causes them to toggle (in several projects they appear to display that a fault has occurred).

    Hopefully this helps.


    Thank you,
    Brett
