agilex5 stop configuration after vout_mode command

Hallo

I use SmartVID with Agilex5 device,

Configure the Quartus to work with LTC3882 device by analog Device

When try to program the device the process stop after VOUT_Mode command from SDM and 0x14 reply from Analog device.

Get the following message:

Error(18950): Device has stopped receiving configuration data

Error(18948): Error message received from device: External hardware access error. (Subcode 0xC809, Info 0x00010014, Location 0x00000C2E)

Error(18948): Error message received from device: Error while sending VOUT_MODE command,

Error(23925): Debug suggestion: Ensure Voltage Regulator supports this command.

Error(209012): Operation failed

Any advise regarding this issue?

Thanks

Asaf

    Hello, 

     

    From the supported VR list(tested) , only LTC3882-1 listed. 

    The PMBUS controller should be the same, but can you check below codes in your firmware:

     

    LTC3882

    ------------

    PAGE = 0

    VOUT_COMMAND -> sets output 0 only

    PAGE = 1 -> not supported

     

    LTC3882-1

    ----------------

    PAGE = 0

    VOUT_COMMAND -> output 0

     

    PAGE = 1

    VOUT_COMMAND -> output 1

     

    if the firmware used LTC3882-1 on LTC3882 device, this explains the 0x14 reply from Analog Device (command acknowledged, but not supported/incorrect mode")

     

    regards,
