SD Card Boot

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/, H...

"Hi,

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 thanks

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

    @RolandoS_Altera

    I had mentioned again, the upstream 01 04 u-boot can work but requires modification as default cyclone V config not longer plug and play as old ones.

    Again, you just repeated what I had said. Why U-Boot could be device dependent from first place.

    I guess there are no point to loop in such.

    I had made my points and either stuff take action or not is a choice from Altera.
