[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+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
