I need help with my jetson nano

I am new to Jetson nano I was trying to remove some space and add some storage using gparted
then i typed sudo apt remove libre* and then i rebooted then it gone to terminal mode the gdm is not starting and i cannot to ping to any sites and when i try to update i get these error

I don’t know of any way to find which packages were removed. Obviously, if it were just libreoffice packages, then the GUI would still work. For networking, were you using Wi-Fi only? Wi-Fi tends to only be brought up in the GUI unless you’ve made some change specifically to cause Wi-Fi to be unmanaged. Wired ethernet should always work even in text mode. So I guess if you used Wi-Fi, and know which package to add back in, then using a wired ethernet cable to your router would probably work. If you have wired, then I think you’re going to end up flashing again. Even with wired I don’t know how to tell which packages need to be added in again.

If you do need to reinstall, then it is important to know which model you have. Is it an SD card model of Nano without eMMC? Or is it a third party carrier board with separate module? For an SD card you could at least keep the SD card you have for reference of things like what is in your home directory, and then create a new SD card. For eMMC you could clone first.

How can i flash it.

cat /sys/module/tegra_fuse/parameters/tegra_chip_id
33
Then which is Jetson TX1/Nano

cat /proc/device-tree/model
NVIDIA Jetson Nano Developer Kit

When i boot it for first time i never inserted sd card it booted normaly then i guess it is eMMC.

It is a third party i guess it has mentioned in the box that it is tanna TechBiz Eagle 101

and i also need to know how to add path for the sd card , I am trying to install deepstream which need lots of space

I also need to know can i install ubuntu 20.04 in it ,is it possible or should i use 18.04?

ASAP please

You need to prepare another x86 ubuntu 18.04 host and use sdkmanger to flash it.

Not able to use ubuntu20.04 because you are using jetson nano.

Oh, I just notice you said “It is a third party i guess it has mentioned in the box that it is tanna TechBiz Eagle 101”.

Then please check with the vendor for their customized BSP to flash.

Actually i have this card and do you have idea how to do this?

I am not sure what do you need from me… This card already told you where to download file and give you commands…

The problem is i cant connect to internet with my jetson

The instructions mentioned on the card is also conducted on another x86 ubuntu 18.04 PC… same as sdkmanager…

You only can use Ubuntu 18.04 on your Nano, and you MUST have a 64 bit PC running Ubuntu 18.04 baremetal (no virtual machine) in order to flash it.

Can you help me the with the putting my jetson in force recovery mode, I am not sure which pin i should connect my jummper


please check

Seems to be similar to the button header of a genuine NVidia DevKit:

Always check the documentation for YOUR board. This is NOT a NVidia board, so the pinout could be different.

Power off. Bridge pins 9 and 10. Power on. Open a shell on the Linux PC and check with lsusb for a NVidia USB device.

I also STRONGLY(!) recommend you to get an USB-3.3V UART cable for the UART#2/Debug UART port. Pins 3(RX),4/TX),and 7(GND) on that connector. This UART is always active, even before Linux has been loaded. You can log into your board even if networking is broken.

Downloads are onto the Ubuntu 18.04 host PC. Jetsons don’t have a BIOS, so they cannot self flash (e.g., you can’t use a thumb drive or DVD to flash with).

I will add that SD card models have QSPI memory in the module itself. The rootfs (the Linux o/s) is on the SD card of those models, and the rest (boot plus equivalent of BIOS) is on the QSPI. It is the QSPI of those models which is being flashed, and which must be valid before an SD card will boot correctly.

On eMMC models flash is pretty much the same thing, but of course you can’t separate the o/s with SD card, it goes on eMMC.

Recovery mode is just an alternative USB state for the Jetson. In recovery mode it becomes a custom USB device, and recovery mode, by itself, doesn’t actually make any kind of permanent change to the Jetson. The recovery pin, when shorted to ground, is like the shift key on a keyboard used to modify some other key and turn it into a capital letter. However, what the recovery pin modifies is either the “power on” or “power reset” state. If recovery pin is shorted to ground (there is a ground pin next to it), and then you either reset power or apply power for power on, you can then release the recovery pin and it will be in recovery mode.

Note: The SD card model pins in question are on the module itself, not the carrier board. They are at right angle to the module under the bottom near the edge. It is hard to see or read, but there is some silk mask marking on it as well.

I have done my flashing , and use the sdk manager to install the jetpak now i got a new problem that when i power off it , it is not turning on , but it is working normal after the flash when i connect to adapter of my nano it is not turning on and it just stay blank and the red light is alone is on

Did you remove die jumper link between FORCE_RECOVERY and GND?

I told you to buy an USB-UART cable. Use this cable to check the output of the Debug UART/UART #2.

yeah i did it and when try to turn on with adapter it just stay blank and the red light is on in the board

now i am getting new error while using sdkmanager

You should export the full logs but not just few lines.

You only shared a info “flash failed”. Why and where it got failed is in previous log…

This is the log file i got
