Hi all
i want to flash .dtb file to nano development kit using this cmd,but it is retuen error,the log and cmd is like this

sudo ./flash.sh -k kernel-dtb jetson-nano-qspi-sd mmcblk0p1

wdg@wdg-HP-EliteBook-8560p:~/nvidia/Jetpack/JetPack_4.2.2_Linux_GA_P3448/Linux_for_Tegra$ sudo ./flash.sh -k kernel-dtb jetson-nano-qspi-sd mmcblk0p1

hello dgw_1985,

you might working with wrong partition name, please check the Nano flash xml for the naming.
for example,

<i>$OUT/Linux_for_Tegra/bootloader/flash.xml</i>

    <partition name="DTB" id="18" type="data">
    <filename> tegra210-p3448-0000-p3449-0000-a02.dtb </filename>

hence, please update device tree partition with -k DTB instead.
thanks

hello JerryChang,
tks for you reply,I use the new flash cmd,but the dtb is not update
1、modify the dts file in tegra210-p3448-0002-p3449-0000-b00.dts

sdhci@700b0600 { /* SDMMC4 for EMMC */
		status = "okay";
	};

	sdhci@700b0000 { /* SDMMC1 for SD card */
		status = "okay";
	};

2、copy the new dtb to kernel/dtb/

cp /home/wdg/nvidia/nano_kernel_out/arch/arm64/boot/dts/*.dtb  kernel/dtb/

3、update dtb

sudo ./flash.sh  -k DTB jetson-nano-emmc mmcblk0p1

4、when the system is reboot.the dtb is not change

zalend@zalend-desktop:~$ cd /sys/firmware/devicetree/base
zalend@zalend-desktop:/sys/firmware/devicetree/base$ cat sdhci@700b0000/status
<b>disabled</b>zalend@zalend-desktop:/sys/firmware/devicetree/base$

5、i used the dtc to convert the final provided .dtb file is ok

./kernel/dtc -I dtb -O dts kernel/dtb/tegra210-p3448-0002-p3449-0000-b00.dtb > tegra210-p3448-0002-p3449-0000-b00.dts

hello dgw_1985,

could you please refer to Topic 1064654 for an alternative way to create signed DTB, and using dd commands for updating.
thanks

hello JerryChang
1、i can not open the link
https://gist.github.com/TIS-Arne/879f47a0310bb46ae426f1b8bb98e5f9
2、I try cope the encrypt file tegra210-p3448-0002-p3449-0000-b00.dtb.encrypt in bootloader/signed with dd command,the dtb still not update

dd if=tegra210-p3448-0002-p3449-0000-b00.dtb.encrypt of=/dev/mmcblk0p10

 3、something is change on nano? the script is working all right on tx2
7

hello dgw_1985,

could you please examine kernel message of your device tree.
please confirm DTB partition is using the latest device tree,
you might refer to below as an example,

$ dmesg

hello dgw_1985,

I’ve verified locally that JetPack-4.2.2 could update DTB correctly with Jetson-Nano.
could you please check you’re replacing correct device tree binary, you should review the flash message to double confirm the DTB file name.
you should update $OUT/Linux_for_Tegra/kernel/dtb/* then perform a partition update with the flash script.
thanks

hello JerryChang
1、can you share all the command in flash DTB,I have a developed kit,i will try in it
2、how to convert tegra210-p3448-0002-p3449-0000-b00.dtb.encrypt to tegra210-p3448-0002-p3449-0000-b00.dtb

hello dgw_1985,

  1. please refer to the documentation, Flashing a Specific Partition.
    you could also refer to below as an example,
$ sudo ./flash.sh -r -k DTB jetson-nano-emmc mmcblk0p1
  1. we don’t support convert encrypt files back to original ones.
