bring up agilex failed, hang at "pte not found"

[shirley_azi]

I have a custom board of AGFB027R25AR0. I want to bring it up, now I follow the article below and encounter the following problems:

"pte not found", and then hang...

4. `Version Info`：

- Quartus: 22.04

- u-boot: socfpga_v2022.10

- ATF: socfpga_v2.10.0

- Board: boot from QSPI(256M GIGADEVICE), no emmc, 1GB SDRAM(I don't know why it can't read 3GB SDRAM??? If I change it to 3GB in dtb, I will failed in sdram_mmr_init_full->`gd->ram_size > hw_size`->‘DDR: Error: DRAM size from device tree is greater than hardware size.’)

- Memory Layout: follow the attached.

Can someone help me?

Hi Shirley

Is it possible that you share the full terminal logs?

This is to see which stage the board have already booted.

Jingyang, Teh

Of course, the complete log is in the attachment pack above named "uboot output info.txt", it stucks at the stage of u-boot SPL...

This is the result that I packaged the logic bitstream and uboot-spl.hex into a new sof and burning the board in.

And I noticed the DRAM size is different with the demo project, then I refer to this post to make modifications. But it still fails to boot...

Hi

Could you try changing the parameter of the "CONFIG_NR_DRAM_BANKS" back to the default and try again?

CONFIG_NR_DRAM_BANKS=2
