AGFB014R24B2E3V Agilex hanging during Linux boot

Hello,

We brought up a board using AGFB014R24A2E2VR0 Agilex parts, but now that we received new boards with the AGFB014R24B2E3V Agilex, the new boards hang in Linux.

Our board has 4GB of RAM. If I reduce the amount of memory available to Linux (passing in up to 'mem=3584M') then the new boards boot as expected.

If I don't reduce the amount available, during the Linux boot process:

- Issues interpreting the devicetree properties(?)

- Bad page state in the process swapper

I've attached the boot log for the failed boot on the new board with the new Agilex variant.

The linux version used is 5.4.34-lts from the linux-socfpga repo, and the u-boot version used is 2020.07 from the uboot-socfpga repo. The .jic for the board was built using Quartus 21.2 tools.

Any idea what could be causing this? Let me know if you need any other information.

Thanks!

    Hi,

    From the boot logs, it can see that your Uboot booting fine, can you share you Uboot device tree and your Linux device tree?

      Hi,

      Also, what is the DDR device part number? And also could you share your Quartus project? I want to see the HPS DDR EMIF IP settings.

        Hi,

        The DDR device part number is: Micron MT40A512M16LY-062EAT:E

        I've attached the Linux and U-boot device tree files along with the Quartus project Qsys and top level files. If you need more from the Quartus project, I can provide it privately.

        Thanks!
