Hello,

We do have a reference for building using the newer flow for the preloader/bootloader but it's for the socfpga_v2019.10 branch and Quartus 20.1, which can be found here: https://support.criticallink.com/redmine/projects/mityarm-5cs/wiki/Building_U-Boot_and_Pre-loader_2019. We have not brought our reference up to Quartus 22.1 or socfpga_v2020.04. A good starting place would be to cherry-pick the top 4 commits from our 2019.10 branch and apply them to Intel's2020.04 branch.

Our 2019.10 u-boot branch: https://support.criticallink.com/gitweb/?p=u-boot-socfpga.git;a=shortlog;h=refs/heads/socfpga_v2019.10

Commits that we applied to intel's 2019.10 branch:

Best regards,
Dan

Hello Dan,

Thank you so much!
I tried to compile the criticalLink repo of U-Boot (socfpga_v2019.10) as in the instruction: https://support.criticallink.com/redmine/projects/mityarm-5cs/wiki/Building_U-Boot_and_Pre-loader_2019

I compiled my FPGA with Quartus 22.1std and not with 20.1.
However, I used the SoC EDS tool 19.1 .

I stopped here:

Do you know if this is due to Quartus version 22.1std (FPGA compilation only) or something is broken with the repo?

I've seen this error in the linux kernel, it's due to using a newer version of GCC (I think GCC 10 was were this broke). I beleive this patch should resolve the issue: https://github.com/altera-opensource/u-boot-socfpga/commit/018921ee79d3f30893614b3b2b63b588d8544f73

Great thanks Dan,

Worked with this warning!

===================== WARNING ======================

This board does not use CONFIG_WDT (DM watchdog support).

Please update the board to use CONFIG_WDT before the

v2019.10 release.

Failure to update by the deadline may result in board removal.

See doc/driver-model/MIGRATION.txt for more info.

====================================================

Is that ignorable?

Best,
Shahad

Yes, I would say that's ignorable. We don't plan on removing the driver from our 2019.10 branch. Though I'm not sure if it's still in any of the newer u-boot branches that Intel is hosting.
