Hi

    I have an board UCD3138OL64EVM-031 and a USB interface adapter, i have down load the program with GUI, and click DO not write program check sum to download, and program have download in. but when i click command rom to execute its program, it's shows below, how can i solve this issue?

    If the firmware enables interrupts and the interrupts are getting invoked with high frequency, the PMBus handler function will not get any chance to get executed.

    The PMBus handler is getting called from the main() loop which has the lowest prioroty. Therefore the GUI commands will NACKed.

    Does an analog comparator invoke an interrupt and its input is floatting on the open loop EVM?

    Is this a newly written firmware that does not clear the interrupt flag at the end of ISR?

    Please make sure that non of the ISRs getting triggered randomly.

    Also, lots of the programs from TI have ROM backdoors in them.  If you can look at main.c, and look at the main function, often you will see lines near the start that describe the ROM backdoor,  Often you have to pull a pin high or low to prevent the code from clearing the checksum and going back to ROM mode.

    Note that these backdoors are there for a reason.  If there is a bug in you code, the PMBus means of clearing the checksum will not work.  It is even possible to screw up the hardware backdoor.  So don't program the checksum on download until you verify that the means of clearing works.

    Hi,

         i use the program of TI Training-labs\Training_labs_source_code\Lab_02 program, it's don't have high frequency interrupts, so i also don't how to solve it , do you have email address, i can send you the code, you may can help to check it .

     Best regards

    As I mentioned above, you need to look at the start of the main function:

    void main()
    {
     // enable JTAG
     MiscAnalogRegs.IOMUX.all = 0;

     //---------------------------------------------------------------------------
     // IMPORTANT: READ BELOW, OR CODE MAY NOT EXECUTE CORRECTLY
     //---------------------------------------------------------------------------
     // tie pin FAULT3 to ground for normal operation
     // tie pin FAULT3 to 3.3V to clear checksum
     if(GioRegs.FAULTIN.bit.FLT3_IN == 1)
     {
      clear_integrity_word();
     }

    Hi

       I have this code in my main loop, and also tie the FAULT3 to 3.3V, it's also shows No device found when i click command rom to execute its program, so please help to find other issue. Could you provide your email address, i can send you email for detail information.

    Best regards

    Hi, 

        I also have try tie fault3 to gnd, but still meet the same issue, no mood now.

    If you can tell me which device you are using, I can give you some advice on how to debug further. Also, after you download, does it go straight back to ROM mode?
