@drozdi70 please build your Linux kernel with patches from https://github.com/Kwiboo/linux-rockchip/commits/next-20250722-rk3528/ and boot using U-Boot from https://source.denx.de/u-boot/contributors/kwiboo/u-boot/-/commits/rk3528 until more patches has landed upstream.

Using a downstream vendor device tree on mainline Linux is not expected to fully work, my tree have a device tree for the NanoPi Zero2 that works without issues on my board.

[drozdi70]

even worst for me.... I sent you private email with boot log and steps...
the procedure is fu** good but why it is not working???
