Error during QSYS Generation: sequencer/sequencer.elf not found (Ubuntu 20.04)

Hello,

I am currently in the process of porting an existing project from Quartus Prime 18.1 to Quartus Prime 22.1. The Platform designer was able to upgrade all the existing IP to version 22.1. However, during the Generate HDL step, the generation fails with the error message:

Error: s0: Cannot find sequencer/sequencer.elf

I believe that this has something to do with the DDR3 UniPHY SDRAM controller not being instantiated correctly, similar to : Related Thread

Any suggestions or help?

With Regards,

Joshua Yun, Critical Link

Here is the stack trace of the error if this is useful:

    Note: I have reinstalled all the 32 and 64 bit libraries mentioned in the Linux installation guide such as referenced in this link

    Hi Joshua Yun,


    If you generate only the DDR3 UniPHY SDRAM IP, do you see similar issue?


    Can you check the software requirement in Table 1 in the link below?

    https://www.intel.com/content/www/us/en/docs/programmable/683472/22-1/software-requirements-07130.html


    If you have done that and the issue still exist, I would like you try on Quartus Prime Standard Edition version 21.1 if possible.

    https://www.intel.com/content/www/us/en/software-kit/684187/intel-quartus-prime-standard-edition-design-software-version-21-1-for-linux.html


    Regards,

    Adzim

    Hello,

    Thank you for responding to the issue promptly.

    I've tried your instructions and here are the results:

    I have verified that all the requisite software is installed and running, specifically the i386 versions of everything.

    I made a minimal example of the only the DDR3 SDRAM IP as shown in the attachment, and it results in the exact same error as posted above.

    It however did work in Intel Quartus 21.1, with the full project generation, and there was no problem generating the sequencer.

    Would this then be a problem exclusive to 22.1, and is there any resolution to this problem?

    With Regards,

    Joshua Yun

    Hello I was wondering whether there was any update to this issue.

    We would prefer to use the latest tools supported by Intel and this is the main problem that is still stopping us.

    Hi,

    we experienced the same issue with 22.1 on Linux, while the same project with 21.1 works fine. Are there any news on this issue?

    Best regards

    Andreas
