Hi,
I have a ubuntu. iso file. I want to install it inside jetson nano. Since the Jetson nano installer comes with zip format with .img file inside, I tried to convert .iso file .img file ( by renaming it ). However that did not boot in Jetson nano.
So if anyone can suggest a way to install / boot a bootable usb ubuntu .iso file in jetson nano, would be great.
Thanks in advance.
As I understand, ubuntu.iso means ubuntu.com released public ISO file.
If YES, I’m sure NOPE! to install it to Jetson Nano directly.
Jetson Nano install image is a pre-configured BSP including kernel, rootfs, and NVIDIA HW specific device drivers/libraries.
If you want to use USB drive as a rootFS, you may refer here:
However, not bootable. Jetson Nano boots from microSD or eMMC.
To flash Jetson Nano, you’d better use a micor SD image directly or SDK manager.
But here, I am copying the jetson nano image. How can I replace with my ubuntu .iso ?
Hi,
Jeston nano image is based on nvidia specific driver. If you just directly copy some ubuntu iso image here, it may not bring the device up.
You could use our rootfs sample in dlc and tool (jetson-disk-image-creator.sh) from driver package.
Hi @WayneWWW,
I am a new user of Jetson nano, So it would be great if you could provide some instructions on how to create a bootable ubuntu .iso for jetson nano.
Hi,
Have you flashed your board with sdkmanager? I think that is what a newbie needs to do at first.
Yes, What I did is, wrote the image to my microSD, booted it normally.
And then I tried to boot a live ubuntu bootable usb in nvidia nano.
Hi,
I think you could read the document here. Especially the l4t developer guide and quick start guide.
The more precise problem is: Why do you want to use a live ubuntu bootable usb ? When you “wrote a image to SD”, there is already a ubutnu (we call it L4T - Linux For Tegra). Why do you want to add or customize?
Actually, the boot process is different from x86 pc. We don’t use a iso file to boot device here.
Actually I want to run/boot the os from RAM. In ubuntu live dvd/ bootable usb their is an option “toram”. You can modify the grub.cfg file and add a mentuentry. Then, all the files are loaded into ram. So, in the end the SD card will not be necessary since everything would be running from RAM.
That’s why I asked you to read the document first… because we are not using grub.
You are correct. I am going through the documentation.
It seems you are using something called u-boot loader. However, in that case, is there anyway to replace the bootloader with grub or any other way, I can achieve booting from RAM :/
You could try to add --rcm-boot in flash.sh parameter and see if it can work or not.
sudo ./flash.sh --rcm-boot board_name mmcblk0p1
If you don’t know what is flash.sh, I tend to let you read the document first to get more familiar with the system.
I followed the steps.
- put a formated a sd card in the board.
- then did the steps mentioned in this link
as the BOARD param i used
jetson-nano-emmc
- and in the last step when I run
sudo ./flash.sh --rcm-boot board_name mmcblk0p1
I get an error
Error: missing rcmdtbfile (/media/user/Linux_for_Tegra/kernal/dtb/tegra210-p3448-0000-p3449-0000-b00-for-rcm-boot.dtb)
Can you suggest anything to solve that ?
Thanks
Hi,
There are two kinds of jetson nano board. Devkit style (sdcard based) and production module (emmc based).
When you say “sdcard in the board”, it indicates your board is the devkit style so no emmc.
It is wrong to use “jetson-nano-emmc” to do the flash. You have to use that one with qspi-sd in its name.
Thanks. However changing the board name resulted in similar error.

Hi,
It seems rcm-boot will be added in next release… rel-32.4.3 still has some file missing.
I am checking this internally.
Hi,
Is the rcm-boot option now available ?
Yes, it should work.
Hi,
So, I have again followed the steps I mentioned earlier. Looks like the flashing was successful.

Reset the board to boot from internal eMMC.
However, after that I tried to boot the jetson nano. Now it only shows the nvidia logo for infinite time and does nothing. So, which behaviour I should expect? does rcm-boot option make it bootable from ram ?
Could you share the uart log?
