UNITHCS08 Prevent popup from "force_background_mode" function

  • Hi,

    i am using the UNITHCS08 library to read data using a usb multilink universal programmer. The programmer has sometimes a problem getting the freescale ic into background debug mode. Then the library shows a popup. Is it possible to suppress the popup? Can you implement another function not showing the popup?

    Thanks
    Steven

  • Greetings,

    Which pop-up message are you talking about? The dialog about power cycling the chip/board? This dialog of power cycling is important if the P&E hardware is not able to enter background mode correctly. When this dialog is shown, the P&E interface is holding the RESET line low while you manually power cycle and prevent the chip from running any code. This allows the P&E interface to connect without any watchdog or other reasons for preventing entrance into background.

    You might see this pop-up on new chips with no code programmed. These chips are running no code so it is always in reset. Without the popup, you will never be able to enter background on new chips with P&E interfaces with no power control features.

    However, if you have the P&E cyclone pro or USB Multilink Universal FX, then these units can power cycle for you and will not show the power cycle dialog.

  • Hi,

    yes I am talking about the dialog about power cycling the chip/board. We would like to power cycle the board automatically. Is there a possibility to implement functions for this using the USB Multilink Universal?

    Thanks
    Steven

  • Greetings,

    No, you bought the USB Multilink Universal which does not have the power capabilities. If you purchased the USB Multilink Universal FX or Cyclone Pro, then it will have this capability and never have to manually power cycle the board. The dialog should only show up the first time you are programming a chip, unless you have bad code running.
