It segfaults when I try a "dup" or "in" command. Not sure if that is some problem of my board or if it is a generic issue with armv7.

Not sure about that particular board, but U-Boot uses the dt in /boot/dtb and then falls back to the built-in tree in U-Boot ($controlfdt). If it does use the fallback (which is the right way to do it), just do dtc -I fs -O dts /proc/device-tree and save it to the location the boot script looks for (check $bootcmd in U-Boot).

[opensuse-arm] ARM-EFI: Where is the device-tree?
Hello, I'm trying to get the USB-OTG interface working on the DE0-nano-SoC (socfpga) board by using openSUSE tumbleweed. The image uses ARM-EFI boot and there is no dtb file on the boot partition. When Linux is running the device-tree is visible on /proc/device-tree and /sys/firmware, so there is a device-tree. But there is no dtb file which I can change for debug purpose. So how to modify the device-tree with ARM-EFI boot? Br, Frank -- To unsubscribe, e-mail: opensuse-arm+unsubscr...@opensuse.org To contact the owner, e-mail: opensuse-arm+ow...@opensuse.org
