I discovered there was a later version (6) of the U-boot patch for the Odroid C2<\/strong>, and also – after more research – found the reason for the compile error…<\/p>\n

It turns out that the GIT version (May 5, 2016) of U-boot currently needs two<\/span> patches..<\/p>\n

The first one is to provide psci_system_reset<\/span><\/strong> for armv8, and details can be found here:\u00a0 http:\/\/article.gmane.org\/gmane.comp.boot-loaders.u-boot\/259967\/<\/a><\/p>\n

The second is the C2 support patch itself, which needs psci_system_reset<\/span><\/strong> to compile correctly, and details of version 6 of the patch can be found here:\u00a0\u00a0\u00a0 http:\/\/article.gmane.org\/gmane.comp.boot-loaders.u-boot\/259968\/<\/a><\/p>\n

After applying these two patches, and adding the Hardkernel binary in sd_fuse, then U-boot compiled and installed OK, but the C2 still failed to initialise:<\/p>\n

I had already found that the latest ‘mainline’ kernel code for the C2 (in linux-next<\/em><\/strong>) would not boot with the Hardkernel-supplied version of U- Boot, which is why this new\/patched version is needed..<\/p>\n
More info when I have made some more progress..<\/p>\n
