Linaro 18.01 dtb not found

Hello,

I try to update to latest debian release (18.01), following instructions here: http://releases.linaro.org/96boards/dragonboard410c/linaro/debian/18.01/

The package android-tools-mkbootimg was not on my system so I manually installed the version 5.1.1.r38-1.1 from debian packages (https://launchpad.net/ubuntu/+source/android-tools/5.1.1.r38-1.1).

When I try to boot the boot image on the board, I see the following problem:
downloading ‘boot.img’…
OKAY [ 1.743s]
booting…
FAILED (remote: dtb not found)
finished. total time: 2.184s

My board does not boot. I suspect something is wrong with the mkbootimg I am using?
Thanks in advance for any help,

I supposed it’s a bootloader version issue. Are you sure you have installed the most recent bootloader/firmware from

http://releases.linaro.org/96boards/dragonboard410c/linaro/rescue/

If you use the SD GUI/installer then the bootloader are updated automatically. but if you use manual method to flash rootfs and boot, then you need to manually update the bootloader.

That was it, thank you !
