Location of cbo.dtb in L4T package

I am changing the boot order with eMMC as the highest priority. I have updated the dts and generated dtb using

dtc -I dts -O dtb -o cbo.dtb cbo.dts

And I can flash the CPU-BL partition alone with

sudo ./flash.sh -r -k CPUBL-CFG --image bootloader/cbo.dtb p3449-0000+p3668-0001-qspi-emmc mmcblk0p1

But while doing full flash, boot order is not updating. I am not sure which file to update int L4T folder. Please help.

Hi,

  1. I think you need to use full flash.

  2. An alternative is to set this in the cboot console. Just interrupt the cboot to enter the console and then

TEGRA194 # setvar boot-order emmc, sd, usb, net
TEGRA194 # boot

Thanks @WayneWWW. I need to know which file to update in the L4T folder. I placed cbo.dtb as bootloader/cbo.dtb, but it does not get updated.

So have you tried the full flash?

Yes I did the full flash.
is the path bootloader/cbo.dtb correct for CPUBL-CFG ?

Hi mohamedhusain1303,

Please replace dtb file to “Linux_for_Tegra/bootloader/t186ref/” folder.
