Hello,

While I was tring to upgrade my kernel from 5.4 to 5.10 I detected that in the debian package there are no kernel image with dtb. So in /boot/bananapi/bpi-r2/linux/ I only have this file uImage_nodt-5.10.90-bpi-r2-main and the dtb directory.

So is it normal that we don't have the image with dtb ? And if yes how can I start with this image from uboot ?

do you use the deb from the choice after build or the pack_debs?

the deb-packing after choice should work

https://github.com/frank-w/BPI-R2-4.14/blob/5.10-main/build.sh#L535

the other is defined in the kbuild system and a bit more complex

https://github.com/frank-w/BPI-R2-4.14/blob/5.10-main/scripts/package/builddeb#L143

here the uImage with dtb is missing...the standalone dtb should be there

make sure in build.sh - function build{} the dtb is copied to $board.dtb, maybe use the build.sh from 5.17-rc tree

as far as i see current code includes the dtb's (also for other boards) in /usr/lib/linux-image-5.17.0-rc1-bpi-r2/

dpkg -c ../linux-image-5.17.0-rc1-bpi-r2_5.17.0-rc1-bpi-r2-1_armhf.deb | grep 'uImage\|dtb'

Ok,you do not build yourself and use deb from releases...this is built with pack_debs.

I will upload fix tomorrow

Thanks for the fix, and thanks a lot for all your work to maintain this kernel.

i wonder why your dtb directory was empty...

thx for report :)
