hi Protx:
 
	Hello, I have just started learning the compilation of Armbian. I am also using the OrangePI3b with the RK3566. I need to study the startup of rknpu in version 6.1.43. I downloaded the latest repository from https://github.com/armbian/build, specifically the main branch. I compiled it according to your compilation configuration. There was an error message upon booting.

	I found that the latest repository does not match your operating instructions. For example, the commit 63073b4af636146d26a7f0f258610eed060c8f34 in the Kwiboog's uboot repository branch rk3568-2023.10 is no longer found. However, the compilation does not report any errors. Could you please share your compilation repository and configuration? 
	Thank you.
