Part Number: TPS6594EVM

Hello TI,

I have trouble connecting the device. The error displayed is

Connected to AEVM Controller, but failed to connect to device TPS6594x_2p0_external on DUTWITHI2C@0*48.

Could you please help me resolve the issue

Regards,

Harsha

    Hello Harsha,

    Can you confirm PMIC part is receiving power? What is the voltage measured on VCCA? (measured at TP1)

    Is the jumper of VIO_IN installed to provide 1.8V or 3.3V? What is the voltage measured on VIO_IN? (measured at TP2)

    Hello Michael,

    Thank you for the reply 

    YES, PMIC is receiving Power supply.

    Voltage measured on VCCA @TP1 is 3.295V

    Jumper of VIO_IN is provided for 3.3V.

    Voltage measured on VIO_IN @TP2 is 3.265V.

    The problem still hadn't resolved even though ACCtrl and ACCtrl Console ports are detected and ACCtrl port is the one that appears in GUI console.

    I would like to put forth an another query in the same lines

    I have used this PMIC(TPS6594) in the design of a custom made board on Xilinx Ultrascale plus FPGA board, for the power supply.

    How do I program the PMIC present in my custom board given that I have Binary file generated from Scalable PMIC GUI in offline mode for TPS6594

    Thanks,

    Harsha

    The easiest way is to follow the instructions from this FAQ post on how to use connect an EVM  to your board and use the GUI.

    Hello Michael,


    I have a issue when using the USB SAA GUI.

    USB to GPIO firmware loader can detect the adapter, but the USB SAA GUI 1.10 says "Adapter not attached".  I want to use USB to GPIO utility to send some I2C commands to the TPS6594Q1. OS is windows 10.

    " I CAN’T communicate with the pod when I use the USB Interface Adapter GUI-v1.10 provided sllc288.

    I expect that TI would provide a firmware/software combination for the adapter/PC that would allow a generic. Please confirm if TI provides any firmware/software combination for the adapter/PC that would allow a modern (Windows10) PC to talk to a generic I2C device such as a TPS6594.

    PS:I have tried using Fusion SAA /I2C debug tool but since Fusion doesn't support TPS6594 it doesn't seem to resolve my problem.

    and 

    Connected to AEVM Controller, but failed to connect to device TPS6594x_2p0_external on DUTWITHI2C@0*48

     This error still hadn't resolved. Can u please help me out

    I appreciate your input to resolve this issue.

    Thanks
