Hi,

I wrote already in April 2020 about this to the mailing list. However, the situation did not improve since then.

The one and only appliance booting on the DE0-Nano-SoC is Leap 15.0, all newer fail.

openSUSE-Leap15.0-ARM-JeOS-socfpgade0nanosoc.armv7l-2018.07.02-Buildlp150.1.1             boots

openSUSE-Leap-15.1-ARM-JeOS-socfpgade0nanosoc.armv7l  end up at u ends up showing the u-boot prompt: "=>"

openSUSE-Leap-15.2-ARM-JeOS-socfpgade0nanosoc.armv7l-2020.02.26-Build1.63

and all newer do not even get to u-boot.

Does nobody beside me use the DE0-Nano-SoC or DE10-Nano?

Thanks for the test with Leap 15.0 that gave a good starting point to bisect the problem. It is located in u-boot and I found this patch that causes the problem:

Good we found the problem. Can you please open a bugzilla so that we can backport the change. Apart from that you should make the upstream aware of the problem to u-boot@lists.denx.de Feel free to CC me if you want. Regards, Matthias

configs: socfpga: disable EFI and ISO partition types

None of the SoCFPGA platforms will support EFI/ISO partition types that is needed for DISTRO_DEFAULTS. SoCFPGA bootroom will only support 0xa2 partition type.

This is needed to help limit the size of the SPL to within the 64k limit that is required for SoCFPGA.

the assumption in the commit message that nobody needs to use EFI for socfpga is wrong, opensuse uses it.

For a test I enabled EFI partiton support for u-boot (not SPL) and with that it is possible to boot a Leap 15.1. Others I have not tested yet.

So I think we need to add a patch to the opensuse u-boot that enables EFI partition support for the de0-nano-soc board.
