Hi,I have an Agilex 5 Modular Development Board which I can boot with the supplied SD Card.I have tried to update to the latest image at Index of /2025.04/gsrd/agilex5_mk_a5e065bb32aes1_gsrd/,However, after programming an SD Card with this image, as far as I can tell, my board doesn't boot. I get no output from the serial port so I don't have any way of debugging.Please can you help with any advice how to proceed to diagnose what is going wrong?Many thanksMalcolm

Hi Malcolm,I hope you have reprogrammed the new .jic image to QSPI before using the sd card image.This .jic image is given on the same link-https://releases.rocketboards.org/2025.04/gsrd/agilex5_mk_a5e065bb32aes1_gsrd/Please confirm.RegardsTiwari

Hi Tiwari,Many thanks for your answer. After programming the QSPI with the image you suggested, I was able to boot linux successfully ( I believe from the SD Card!).Please can you give a brief explanation as to why this was necessary? What was preventing linux from booting?Many thanksMalcolm

Hi Malcolm This could be due to the mismatch in the hardware design.For the the Hardware Design in the GSRD, it is HPS first configuration.It is separated into initial configuration for the HPS and the core configuration of the FPGA.The initial configuration is stored in the QSPI Image and the second configuration is in the SDCard.For a normal boot, both configurations must be of the same build.That could be the possible problem you are facing. I could not determine that without looking at the error from the bootlog.RegardsJingyang, Teh

Hi Do you have any follow up question on this?RegardsJingyang, Teh

Hi Jingyang,Thanks, I think that makes some sense but I will have to re-read the information about how the configuration scheme works - it is not like the Cyclone V SoC that I am used to!When you mentioned looking at the bootlog, how can I do this if I don't get anything out on the serial port?ThanksMalcolm

Hi Brian,
It seems like there is a lot of confusion. Maybe it would be helpful for you to start a new thread that clearly states your question(s) and we can try again?

  According to this quote aka the first comment in this ticket.
  Could you read "no output from the serial port" <-----
  
  Such behavior is 100% aligned with 2025.01 2025.04 U-Boot Altera github repository on C5 devices.
  I don't see why all stuff comments are so confused on this same issue.
  
  And I had already explained the issue and the possible solutions accordingly, which might not fix as inherent issue of this early year that Das U-Boot upstream had changed the SPL settings entirely.
  
  I no expert on Uboot but undergo minor study on such.
  
  So if there are system Engineer from Altera should know very well.

    Hi Brian
    So you are saying that if you use Altera U-Boot from 2025.01 and 2025.04 branches in Cyclone V, there is no output from the serial console similarly to what is being reported in the Agilex 5 Modular dev kit when using latest branch in Das U-Boot repo?
    If this is the case, I think that for Cyclone V this shouldn't be a surprise, since the latest code validated for Cyclone V uses the QPDS24.1STD_REL_GSRD_PR tag in Altera Repos as it can be seen in https://altera-fpga.github.io/rel-25.1/embedded-designs/cyclone-v/sx/soc/gsrd/ug-gsrd-cve-soc/#source-code
    Cyclone V is aligned with Quartus STD releases, which occur only once a year, so it is not expected to work with U-Boot branches 2025.01 or 2025.04.
    In the case of Modular Dev Kit, this should work with Altera U-Boot branches from 2025.01 and 2025.04, but since not all the updates in the Altera repos have been pushed to the Das U-Boot repo, it possible to observe this issue, so that's why we recommend to use the Altera repo content.
    Thanks
    Rolando
