Unlike x86, there are no "strange" filesystem requirements for ARM booting (that's all handled by U-Boot), so you can just rsync any appropriate root filesystem onto your uSD (or eMMC, or whatever). If you don't specifically need to recompile U-Boot or the kernel, you can simply use these as-is from any example image for the DE10 and just replace the rootfs. This may be helpful to get started, even if the kernel isn't patched with PREEMPT_RT (you can update the kernel later once you have a working system). If you want to build from source, there are lots of differing instructions which makes things confusing. There are Angstrom bitbake recipes, Altera custom Makefiles, and various other instructions floating around. I usually build a kernel following the "Building Kernel & U-Boot Separately From Git Trees", which is page 4 of the "Compiling Linux" documentation for the GSRD. One example (make sure to click over to #4): https://rocketboards.org/foswiki/Documentation/GSRD160CompilingLinuxArrowSoCKitEdition -- Charles Steinkuehler char...@steinkuehler.net -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
