Hi,

We have built our BSP based on Jetson nano L4T 32.3.1 applying few patches. we are able to flash it to nano emmc but one of our customer is having below issue. can you please help?

After running the command sudo ./flash.sh jetson-nano-emmc mmcblk0p1 it ends with and error Error: missing dtbfile (/home/steel99xl/Downloads/Jetson/Linux_for_Tegra/kernel/dtb/tegra210-p3448-0003-p3449-0000-b00.dtb).

Attached the log fileOutPut.txt (2.2 KB)

hello venkatraman.bhat,

is this device tree binary actually present in the user’s local host machine?
besides, it’s flash configuration file to indicate the DTB_FILE name after processing the board version.
thanks

Hi, Thanks for that. We have tested on 4GB module, this flash config file do not point to tegra210-p3448-0003-p3449-0000-b00.dtb and we se no such file in our dtb path.

if we try to flash on 2GB module do we get this error?
To flash the kernel on dtb on Jetson Nano 2GB using the default file /kernel/dtb/tegra210-p3448-0003-p3542-0000.dtb:

$ sudo ./flash.sh jetson-nano-2gb-devkit mmcblk0p1

this command is right?

hello venkatraman.bhat,

yes, you may flash a specific partition instead of flashing the whole device by using ‑k options.
please check developer guide, Flashing a Specific Partition.
thanks

Ok, I do not want partition, I want to flash default whole device then?

hello venkatraman.bhat,

you may review the flash configuration files,
there’s DTB_FILE file name determination after processing the board version.
thanks
