I2C Remote System Upgrade Example - No output on the Serial terminal

Hi,

I am trying out the below i2c example for RSU with Max 10 Evaluation kit

https://fpgacloud.intel.com/devstore/platform/16.0.0/Standard/i2c-remote-system-update-example/

I am using the files in final_programming_files folder to try out the project. For the 10M50 board, I did all the steps that document mentioned in following sections and didnot get any error in this process.

"Programming Master Image into Max 10M50"

"Programming Slave Images 1 and 2 into CFM 1 and 2 on Max 10M50"

But, I am not able to see anything on the serial terminal as shown in the example. Also connected the config_sel pin to 0 by turning ON the SW2.2 at the board.

    @lpkruger I have followed the example in the above link. Can you please help me with that. Although I program the files as described, I could not get any thing on the Serial terminal

      Hi, I have one more query. In the example below

      https://fpgacloud.intel.com/devstore/platform/16.0.0/Standard/i2c-remote-system-update-example/

      IN Pg-19 the below statement is written

      "Note that this section does not contain instructions for regenerating the programming files used for the UART section of this example (“pfl.sof”, “RSU.sof”, and “nios_firmware.pof”). These files are part of a separate project which can be found separately on the Altera Design Store."

      Can you please point me to projects in Altera design store containing the above files

      I have tested AN741 and was able to trigger the Remote system upgrade from UART. But my final system is something similar to the once explained in

      https://fpgacloud.intel.com/devstore/platform/16.0.0/Standard/i2c-remote-system-update-example/

      Where I need to update 10M16 using 10M50. So it would be grate if I could get the source files that generated the output files :“RSU.sof” and “nios_firmware.pof” mentioned in those examples

      Thanks in Advance.

    I cannot test that, as I do not have the EDS(Nios 2) license. I was trying out RSU using only the output files in the folder "final_programming_files".

    Hi,


    You can find the design file in AN741. I believe you are working on it as I am supporting case 05123561.

      Hi,

      I think AN741 and I2C example are different, as the I2C example has the I2C transfer of image to 10M08, which is not present in AN741 example.

      So, I guess the design files will be different for I2C example. Can you point me those design files of I2C example.

      Regards,

      Ravi

      Hi,

      Let me try to clear things. The RSU via I2C design file(i2c_master.c) is present in the design example folder. But this is different from nios_firmware.pof. And nios_firmware.pof is not the same as the one in AN741 also.

      There should be a different design for RSU.sof and its not I2C_RSU. The user guide says these are files from separate project on Altera Design Library

      Hope I brought some clarity

    Hi,

    After checking with my team, by looking back at your first post regarding not able to see anything on serial terminal, kindly try to check again the theory of operation starting on page 3 of the I2C RSU user guide.

    Also, on page 16 of the I2C RSU user guide, please check again the USB to UART system setup. Make sure to select the correct COM port. This to ensure the device is correctly connected.

    For serial port setting, try to play with the Baud Rate setting. You can try to change the Baud Rate.

      Hi.

      Thanks for the suggestions. But I think there is no issue with UART and the Baud rate as I am able to run other codes and see the output on the Serial terminal. I think the issue is with the loading of nios_firmware.pof in to QSPI flash, because this never passes the verify step in the programmer. I really doubt whether the nios_firmware is loaded or not.

    Hi,

    I assume the issue with output terminal has been solve.

    Also from your response,

    • What do you meant by never passes verify step in the programmer?
    • Do you see any error message? Please provide the screenshot.

    Thank you.

    Regards,

    Aiman

      Hi,

      Below are the screenshots for program of nios_firmware in to QSPI flash

       

      Verify of nios_firmware in to QSPI flash

      Hi,

      I could not see any specific error message except the Failed message at right top corner.

    Hi,


    Normally there will be error message, please check quartus interface under message tab. It is located at the below of quartus.
