TPS6594EVM: Some questions about EVM GUI started

Part Number: TPS6594EVM

Hi Team,

My customer is started with a TPS6594EVM. Some questions with the GUI using.

  1. Is there any relationship between the Quick Start, NVM Configuration and Register Map pages in GUI? Can I skip the Quick Start and set the NVM Configuration directly? After finished the NVM setting, do we still need to set the register map?
  2. Is the PFSM in NVM Configuration needs to be draw by us? How can I figure out the trigger between each status? And how do I know the power up/down sequence?
  3. Is the Program Device can write only once to TPS6594?

    No, there is no relationship.  The quick start and Register map pages provide a way to read and write to the PMIC registers.  The NVM configuration page is intended for building and programming NVMs.  Yes, the quickstart and register map pages can be skipped.

    Yes.  Triggers are defined by you.  When you select an arrow between states you will see on the right hand side the dialog box for selecting the trigger, (https://www.ti.com/lit/ug/slvubt8a/slvubt8a.pdf#page=39).  Power sequences are also defined by you.  Select the power sequence button and then add a new sequence(https://www.ti.com/lit/ug/slvubt8a/slvubt8a.pdf#page=31).

    No.  There is no limit to the number of program cycles.  However, you can elect to lock the NVM so that it can no longer be programmed.  Do not select this.https://www.ti.com/lit/ug/slvubt8a/slvubt8a.pdf#page=48

    Hi Chris:

    We are trying to write the .bin file from Arbe into the GUI, but their is no outputs.

    Does this EVM has a limit of write times? It shows EEPROM Unlocked Failed today, we didn't select lock in previous operation. Then it can't recognize the port and can't find the device any now.

    Hello Frank,

    The ARBE binary was written for the PG2.0 silicon.  In the GUI device selection, you have selection PG1.0 (TPS6594x-1.0).  Please confirm which version of silicon you are using.  From the register map page you can observe the DEVICE_ID (register 1 of page 0). 

    In the PG1.0 silicon, the EEPROM cannot be unlocked from the safe_recovery mode.  

    Regards,

    Chris
