TPS65988EVM: TPS65988EVM

Part Number: TPS65988EVM

Hi,

I want to understand the function of Push button on EVM board.

I need more detail about the function of each switch.

For S1, I have following questions.

  1. Why , we need a soft reset?
  2. Is there any circumsetences when we must need to reset the TPS65988 chip?
  3. Should i have it on mass production board?

For S6, , I have following questions.

  1. What is the purpose of booting the PD controller?
  2. Is there some specific configuration that must be load through booting process?
  3. Should i have it on mass production board?

My last question is about mass production programming.

What is the best method to upload the configuration files in the TPS65988 and TPS25750 for mass production?

Right now, i am using AArdvark to upload programs.

Thanks

    1. Why , we need a soft reset?
      1. A soft reset allows you to reload the patch without power cycling the device. You may not need a button on your own design, but this provides a way for hardware to trigger a signal that resets the device through the HRESET pin.
    2. Is there any circumsetences when we must need to reset the TPS65988 chip?
      1. This is case by case, there may be failures where a reset is the best choice.
    3. Should i have it on mass production board?
      1. This is case by case and is up to you. If you think you need the button, leave it in. If you don't need the HRESET feature, the datasheet recommends grounding the pin.
    1. What is the purpose of booting the PD controller?
      1. Booting from the SPI flash loads any updates and patches to firmware, as well as the configuration that you make in the configuration GUI
    2. Is there some specific configuration that must be load through booting process?
      1. The specific configuration depends on your use case and is configured through the GUI.
    3. Should i have it on mass production board?
      1. You most likely do not need the switch unless you plan on using the default rom image.

    Typically the board manufacturer will be able to program the SPI Flash if you provide them the binary file. Sometimes the component manufacturer will also do this. You should reach out to the board manufacturer to see what options they have.

    Thanks and Regards,
