Question

Interface STM32 with ADIN1110

I am trying to interface STM32L432KCU6 with ADIN1110. Volktek IMC-553 media converter is used to bridge the MCU board with laptop. I am trying to send UDP data. But communication is not succesful. I have a custom project board with the MCU as well as a nucleo board. I tried on both. However I have succesfully interfaced STM32 with ENC28J60 and communicated with laptop over UDP. I am currently doing development in Zephyr. However if any one can support in Arduino/STM32 Cube or any other, I am OK. My intention is succesfully interface ADIN1110 with STM32 and communicate data and visualise in laptop.Thanks in advance.

Welcome to the forum.

Please see How to write your question to maximize your chances to find a solution for best results.

 

The ADIN1110 is an Analog Devices product - nothing to do with ST:

https://www.analog.com/en/products/adin1110.html

Have you studied the AD documentation, and tried the AD drivers, etc?

Have you contacted AD to verify your design?

The EVAL-ADIN1110 Evaluation Board for this part uses an STM32 - so have you looked at the code for  that?

 

PS:

Do you have basic SPI comms working with the ADIN1110; eg, can you read the IDVER, PHYID, and/or CAPABILITY registers?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    Hi, thanks for the reply. I am unable to read registers of ADIN1110. I checked SPI communication with 2 nucleo boards and it works fine. I believe something specifically related to ADIN1110 is absent or wrong in my code.

    You mean 2 Nucleo boards talking to each other ?

    That really doesn't tell you much about communicating with the ADIN1110 !

    So check the ADIN1110 datasheet: do you have the connections correct, correct SPI Mode, etc, etc?

    Again, the EVAL-ADIN1110 Evaluation Board from ADI uses an STM32 - so have you looked at the code for  that?

      I have checked the datasheet. Connections and SPI modes are correct. But unfortunately not pinging.

      I tried Sparkfun support and Arduino based code. But both my Zephyr code and Arduino code are both showing same issue. Couldnt establish connectivity.

      If your basic SPI comms isn't working, then there's no point worrying about ping !

      You need the basic SPI comms working first - if that's not working, nothing else can possibly work.

       

      Have you used an oscilloscope to verify that the SPI signals are clean, correct levels, etc?

      Have you then used an analyser to verify the SPI messaging ?

      So what about the ADI code? The stuff from the actual manufacturer of the chip?
