AFE7769EVM: Not able to load IGUI, in simulation mode

Part Number: AFE7769EVM
Other Parts Discussed in Thread: AFE7769,

Hi Team,

   I'm new to this Latte software, i am trying to run and configure using IGUI in simulation mode for AFE7769 EVM, i have followed the instructions in user guide. need support to run simulations.

Here is my log window. 

    

why is this error message coming in devinit.py script.

    Hi Sivaprasad,

    This means that the USB interface driver (FTDI chip) on the AFE7769 EVM may not be installed properly. I will ask Kevin to help you on this.

    Hi Kang,

        Thank you for your response.
         i will be waiting for the further updates.

    Sivaprasad,

    When I disconnected the USB cable from the AFE7769EVM, I was able to reproduce the errors and warnings that you reported in your thread, see image below.  The messages in yellow are warnings, not errors, so you don't need to worry about them.  Couldn't load iGui error happened because as of now, AFE7769EVM still doesn't have a iGui.  We have engineers that are currently developing the iGui, but it won't be ready to the public until later this year.  

    After you run the setup and devinit.py scripts, to generate the configuration file, you can modify the parameters inside the bringup script base on your own application and run(F5) the bringup script afterwards.  When you run the bringup script, you might see error like Fuse farm load autoload done didn't go high, this is because the EVM is not connected to the PC.   Other errors like Sysref to RX AB, Read 0; expected:3, Comma Align Lock Lane0: False; Please check if the transmitter is sending data and eye is good. are related to the JESD link between the AFE and FPGA, we see these type of errors all the time when running the bringup script, and it should not prevent you from generating the configuration file.  You can just ignore them for now. 

    To find out where the configuration file is saved, you can type ASTERIX_DIR in the command line window.  On our lab PC, the configuration file is saved under C:\Users\dc-wi\Documents\Texas Instruments\Latte\lib\

    Hi Kevin,    

        The Reason we are looking for the simulation mode to work is that we want to run some testes to know what are the minimum and maximum limits of values we can give for each parameters and also we have generated a MATLAB data for signal to transmit we need to know how to feed that as input to this AFE7769EVM Board.. we don't want to damage the boards with these tests. 

        How do we send those data to the board and what are all the things we can do without connecting the board as of now.

    Hi Kevin,

    I ran the scripts and generated the config file, can you please explain to me use of this file in terms of generating simulations. or usage of the config file.

    Hi Sivaprasad,

    Yesterday was US Memorial Holiday. We will review your questions and get back to you.

    In simulation mode, the only thing you can do is generating the configuration file.  To transmit a tone at the output of the Tx channel, you need to power up the AFE7769EVM, connect it to a FPGA and load the waveform that you want to transmit to the FPGA.  There are also commands that you can use to transmit CW tone.  On our bench, we are using the Xilinx TSW14J58W.  More information about the FPGA can be found in the link below:

    https://www.ti.com/lit/ug/slwu094/slwu094.pdf?ts=1654005800780&ref_url=https%253A%252F%252Fwww.google.com%252F

    If you don't have a J58 FPGA or don't feel comfortable powering up the AFE7769EVM, can you explain to us what tests you want to take, we will see if we can take the measurements for you on our bench.

    The purpose of the configuration file is to configure the AFE7769.  Once customer receives the configuration file, they load it into the AFE7769 chip.  If everything works as expected, the AFE7769 chip should do what the configuration file wants the AFE7769 to do.  If AFE7769 is a house, configuration file is like the floor plan of the house.  To evaluate the AFE7769EVM, you can just power up the board and change the parameters inside the bringup script, run the script and see if AFE7769EVM works or not.
