NX does not boot after flashing DTB only

[roey.bh]

sudo ./flash.sh -r -k kernel-dtb jetson-xavier-nx-devkit-emmc mmcblk0p1

After flash complete, I can see the Nvidia Logo and after that black screen with a blinking cursor:
This is the UART boot log:

Flashing a single partition with ./flash.sh causes a boot loop

I was trying to flash only cboot with the following command but although the flash command exits normally, it puts the module into a boot loop. The only way to recover is to flash all. # ./flash.sh -r -no-systemimg -k cpu-bootloader jetson-xavier-nx-devkit mmcblk0p1 [0000.024] W> RATCHET: MB1 binary ratchet value 4 is too large than ratchet level 2 from HW fuses.

The only way to currently flash is to flash everything (except the system image)

$ sudo ./flash.sh -r --no-systemimg jetson-xavier-nx-devkit-emmc mmcblk0p1

I use the following Makefile target to make DTB updates easier (well, easier in my opinion at least!). With these rules I can execute make sync-dtb. We have a few more rules that make it so we can execute make sync no matter the Jetson device. It updates the kernel and dtb without putting the device in recovery mode. I find this very convenient for kernel development!

sync-dtb: sign-dtb
	$(vecho) "SYNC     $(SIGNED_DTB)"
	$(v)scp $(SIGNED_DTB) @TARGET_HOST@:~/device_tree.dtb.encrypt
	$(v)ssh @TARGET_HOST@ sudo dd if=device_tree.dtb.encrypt of=/dev/disk/by-partlabel/kernel-dtb

$(DEPLOY_BUILD_PATH)/boot/%_sigheader.dtb.encrypt: $(DTB_BUILD_PATH)/%.dtb
	$(vecho) "SIGN      $^"
	$(v)cd $(DEPLOY_BUILD_PATH)/boot; \
		@L4TDIR@/bootloader/tegraflash.py --chip $(FLASH_CHIP_ID) \
		--cmd "sign $^" --skipuid;

sign-dtb: $(SIGNED_DTB)

SIGNED_DTB=$(DEPLOY_BUILD_PATH)/boot/$(patsubst %.dtb,%_sigheader.dtb.encrypt,$(notdir @DTB_FILE@))

[gtj]

That’s one way. Another way is to just copy the signed dtb and the .sig file to /boot/ on the device and add an FDT line to extlinux.conf. Cboot looks for the file first before pulling from the flash storage.

[D3_growe]

Oh, I didn’t realize cboot was back to reading FDT from extlinux.conf. That’s great if it’s doing that again!

Hi,
It looks like I used the wrong DTB.
We are developing camera drive for the NX. The resulted DTB is :
tegra194-p3668-p3509-0000.dtb
And that’s the one that caused the NX to halt during boot.
Once I have changes the dtb to:
tegra194-p3668-all-p3509-0000.dtb
and flash using this command:
sudo ./flash.sh -r -k kernel-dtb jetson-xavier-nx-devkit-emmc mmcblk0p1
The system was able to boot.
