Configuration is wrong, you are using the one for external NIC while Opi PC has only internal.

1. BR2_LINUX_KERNEL_INTREE_DTS_NAME="sun8i-h3-orangepi-plus"

Copy code

change to:

1. BR2_LINUX_KERNEL_INTREE_DTS_NAME="sun8i-h3-orangepi-pc"

Copy code

And it might work if you have the right kernel source ... I am not sure every board is already mainlined.

Beware, H3 mainline kernel does not yet have thermal protection and if you fail to build, you can use our tools, they are working and are more optimized for H3 boards:

Thanks for reply, i am using Armbian on orangepi it works great for orangepiOne , i want boot up time less than 5 Sec ,
is it possible to speed booting , how to stop HDMI and other unwanted pakeges from Armbian
      I think i have to compile what is good start point

Thanks for helping out Igorpec.

You don't need to recompile a kernel - just alter /boot/script.bin (convert to fex, edit and convert back) board configuration and disable HDMI. Check this article:
http://docs.armbian.com/Hardware_Allwinner-H3/

Armbian is already lightweight and optimized system so it's hard to speed up much. Get a good SD card and remove not needed packages, but you won't gain much.
One thought - you can gain some time in uboot since it waits 3seconds for user input - in this case, you need to reconfigure and recompile.
