SD Card Boot

Thanks for posting your solution, Brian.

Just for clarity - are you saying the 2025 Uboot works or no?

Thanks,

Sue

Hi Rolando, I am pleased to hear that you are updating the build instructions for Agilex 5! I have been trying to follow the instructions in this link

https://altera-fpga.github.io/rel-25.1.1/embedded-designs/agilex-5/e-series/modular/boot-examples/ug-linux-boot-agx5e-modular

for the Boot from QSPI but have given up as, having got around a number of errors, I managed to create and program my QSPI, only for to fail to boot (I can't even open the Serial Port), at which point I have no way to debug what is happening...

One error that I have relates to bl31.bin which i built successfully in the Boot from SD Card stage, but when I run bitbake in the QSPI stage, i get this error:

DEBUG: Executing shell function do_compile cp: cannot stat '/home/malc/agilex5_top/yocto/build/tmp/deploy/images/agilex5_dk_a5e065bb32aes1/bl31.bin': No such file or directory WARNING: /home/malc/agilex5_top/yocto/build/tmp/work/agilex5_dk_a5e065bb32aes1-poky-linux/u-boot-socfpga/v2025.04+git/temp/run.do_compile.19724:163 exit 1 from 'cp /home/malc/agilex5_top/yocto/build/tmp/deploy/images/agilex5_dk_a5e065bb32aes1/${file} /home/malc/agilex5_top/yocto/build/tmp/work/agilex5_dk_a5e065bb32aes1-poky-linux/u-boot-socfpga/v2025.04+git/build/${config}/${file}' WARNING: Backtrace (BB generated script): #1: do_compile, /home/malc/agilex5_top/yocto/build/tmp/work/agilex5_dk_a5e065bb32aes1-poky-linux/u-boot-socfpga/v2025.04+git/temp/run.do_compile.19724, line 163 #2: main, /home/malc/agilex5_top/yocto/build/tmp/work/agilex5_dk_a5e065bb32aes1-poky-linux/u-boot-socfpga/v2025.04+git/temp/run.do_compile.19724, line 301

PS. I am using WSL2.

In the boot from QSPI section, it is unclear what, if anything I need to do with the SD Card...

The 2 links below don't work.

I am confused what actually you are asking or confirming?

For Das U-Boot 2025 01 and 04 had changed the SPL detection.

While 2025 07 the stack is even changed which at this stage I can't make it boot on any Cyclone V device.

For both Altera Git U-Boot or Das U-Boot I had confirmed 2025 01 04 and older revision all aligned excluded dts file.

Aka modifications to boot properly on SD only platform.

I had not followed any altera boot document nor the rocket forum b.c. the follow is not telling any backward compatibility.

However it is actually allow on older "hps_isw_handoff" folder to reused on new Python script.

So I am not sure what you are asking for.

As far I can tell I have no idea why the 2025 07 cannot boot properly.

There are too many patches on SPL and the stack change include start.S.

Hello Brian

Our documentation and HPS releases are based on the Altera repositories (https://github.com/altera-fpga). Please look at our Release Notes page that shows what versions of each component we released:

https://github.com/altera-fpga/gsrd-socfpga/releases/tag/QPDS25.1.1_REL_GSRD_PR

In the case of U-Boot, the latest release is based on 2025.04. The next release will be based in 2025.07.

We are working to push all the updates that we have in our repositories to the repositories that the community supports (i.e. https://github.com/u-boot/u-boot) but it's possible that the latest code in the Altera repos are not yet propagated to the community repos, so this is the reason why we direct our customers to use the Altera repos.

If you have any further questions about Cyclone V, it would be better to open a new case, so we can focus in this case to solve the issues related to Agilex 5.

Thanks

Rolando

@JingyangTeh_Altera

Yes in other post you had reported 2024.07 is well tested.

However, 2025 01 04 is already released a while, not sure the definition of latest.

The most update now is 2025.10 so I am just thinking the resources are not put on C5 series not b.c. of the word of latest.

Thank you

@SueC_Altera

You are also misread the topic.

What this original ticket is about SD Card U-Boot booting on Ag5.

I don't understand why you guys will consider U-Boot is device dependent.

As for what the title mentioned is no device orientated.

As such I cannot understand at what points / posts / questions that are not U-Boot related question from first place.
