Hi I have FSBL and SSBL. SPL uboot starts successfully and u-boot.img is loaded successfully but it hangs on 'boot_from_devices' function and 'fit_find_config_node': fit_find_config_node: Missing FDT description in DTB No matching DT out of these options: Firmware image with one or more FDT blobs boot_from_devices error SPL: failed to boot from all boot devices I have suspicion that I wrongly create u-boot.img. My system build do this by executing: ./tools/mkimage -f auto -A arm -T firmware -C none -O u-boot -a 0x100000 -e 0 -n "someName" -E -d u-boot-no-dtb.bin u-boot.img >/dev/null The same issue occurs when I use u-boot-dtb.bin version. The value 0x100000 is the value stored in CONFIG_SYS_TEXT_BASE. And this uboot and spl is somekind of experimental software which is in the middle of creation. Could anyone try to guide what might be possible the reason of the issue as I am a bit new in u-boot development? BR Tomek
