Hi all again,

I've managed to build everything, and to create the image etc., but I'm 
having troubble with the .dtb file

So, I've added sun8i-h3-orangepi-plus.dts to the dtb/allwinner Makefile, 
so that it gets built with the MODULES_EXTRAS option in the kernel 
config file.

So far so good, the .dtb exists as sun8i-h3-orangepi-plus.dtb and is 
installed in /boot/dtb which is placed on the ufs filesystem (2nd 
partition of the SD card).

When I switch on the device, u-boot and ubldr start fine, but ubldr 
complains about the missing .dtb - So obviously it's confused by 
something. I guess the .dtb is either in the wrong place or it has the 
worng name. In either way, I need to tell ubldr what to look for. How do 
I do that?

On my dreamplug I don't use ubldr, but boot kernel.bin directly from 
u-boot. There I use the following kernel config options:

options         FDT_DTB_STATIC
makeoptions     FDT_DTS_FILE=dreamplug-1001.dts

which cause the .dtb to be built into the kernel. Would that work with 
ubldr as well? (I don't need a separate .dtb, so whatever works is fine 
with me..

Do you have any hints?

Thanks,

Mat
