Problem description and steps to reproduce:
Hello, i'm using firefly roc-3588s-pc with official sdk - rk3588_linux_release_20250114_v1.4.0g and need to modify device tree to support spi in user space.I modified dts file: roc-rk3588s-pc-mipi101-M101014-BE45-A1-v13.dts from kernel source and compiled firmware with build.sh script for configuration file: roc-rk3588s-pc-BE45-A1-ubuntu.mk.
After successfull flasing and booting to the new system (with ubuntu 22.04 rootfs), i see old dts content through /proc/device-tree.
My custom dtb file actually present in /boot partition(ref rk-kernel.dtb points to modified dtb - roc-rk3588s-pc-mipi101-M101014-BE45-A1.dtb), but u-boot loads some old dtb file - /roc-rk3588s-pc-mipi101-M101014-BE45-A1-v12.dtb.
What i'm dogin wrong, is there some way to tell u-boot to update linux dtb file or i missed something in sdk configuration.
I've attached booting log file.
