Jetson TK1 Ethernet

Hi,
i bought a new Jetson TK1 a week ago, and since then i am batteling with the internet.
i cannot connect to the internet. Wifi says that no nl80211 found, and ethernet disconnects directly after i log into my jetson. has anyone had such issues? any help please? is there anything i am missing?

Hi alayan,

What does it mean? " ethernet disconnects directly after i log into my jetson"?

Did you use BSP from jetpack?

thanks for your reply.
i followed up the procedure to install linux for tegra and flash the Tegra with L4t.
as soon as i log into my tegra, i get the message connection disconnected you are now offline.
ifconfig shows an IP of ::1/128
iwconfig shows (rmnetctl, sit0, dummy0, lo, eth0, op6tnlo) no wireless extensions.
nm-tool shows eth0 typre wired, state unavailable.
in system settings network shows an unplugged wired cable! even though i have an ethernet cable connected.
as far as i know, as soon as you install linux for tegra, and plug an eth cable, then internet should be recognized. did i miss anything?

in “/etc/network/interfaces.d/” i have

interfaces(5) file used by ifup(8) and ifdown(8)

source-directory /etc/network/interfaces.d

and in etc/udev/rules.d i dont have the 70-persistent-net.rules files.
can that be the problem`?

I doubt maybe a hw issue. Could you figure out some method to get dmesg(kernel log) when boot up?

dmesg shows no problems, it only shows my HDMI and EDID… but nothing to network connections. One thing though,
when i sudoedit interfaces in /etc/network and add auto lo iface lo inet loopback then network manager fails to load. everytime i manipulate that file, network manager fails.
is there a way to control my tegra from a host pc and like do an upgrade? or should i go for ubuntu 16.04?

Does this show any errors?

sha1sum -c /etc/nv_tegra_release

When you did your flash there would be a file “bootloader/system.img.raw”. What is the exact size of this file? On the Jetson, what is the available space from “df -H /”?

NOTE: The most recent version of L4T is R21.5 which produces Ubuntu 16.04. Host side is of course a separate topic, but it sounds like you are interested in the Jetson’s Ubuntu version. Some notes on flashing a Jetson by command line (the minimal flash):
https://devtalk.nvidia.com/default/topic/982779/jetson-tk1/how-to-perform-a-correct-fresh-ubuntu-install-on-jetson-tk1/post/5040584/#5040584

sha1sum -c /etc/nv_tegra_release is a sudo : lshw: command not found.

i havent been able to connect not even once to the internet to do an update or something like that, so there are a lot of packages yet to be installed. Have i mentioned flashing L4T versions (21.1.0 and 21.3.0 and 21.4.0 and 21.5.0).
system.img.raw is a 15 GB file in all versions.
df -H returns
15 G in /dev/root (17% used) Mounted on /
984M in devtmpfs (1%used) Mounted on /dev
none 4.1k (0%used) Mounted on /sys/fs/cgroup
none 199M (1%used) Mounted on /run
none 5.3M (0%used) Mounted on /run/lock
none 993M (1%used) Mounted on /run/shw
none 105M (1%used) Mounted on /run/user

i tried a direct wired eth connection (remote connection) with the host pc (Ubuntu 16.04) and yet no recognition to that network. it is like Networkmanager is blocking everything. The red LED turns on as soon as an eth cable is plugged in. Ive never seen the green one on.

Is there a way to fix it? i really need that jetson to get working…thanks for your help.

I think it would be better to paste all dmesg though attachment for us to check if anything is missing.

ok

Is this correct?

sha1sum -c /etc/nv_tegra_release is a sudo : lshw: command not found.

If this exact command fails, then it implies the installation itself is not valid:

sha1sum -c /etc/nv_tegra_release

Any user should be able to run that command and get “OK” for every line of output. If not, then it may be flash occurred without the “apply_binaries.sh” step.

i tried the sha1sum command again, it seems i was writing it wrong.

sha1sum -c /etc/nv_tegra_release

That confirms the correct drivers are in place. It sounds like the issue is occurring with the original unflashed installation, is this correct? If so, there may still be a problem, but chances are good that the next best debug step (and perhaps even a cure if not a hardware issue) is to flash to R21.5 (the most recent L4T version on a TK1). There were just a lot of bugs in the original R19.2. Can you verify that you have not yet flashed?

FYI, the R21.5 downloads are from here:
https://developer.nvidia.com/linux-tegra-r215

You can flash with JetPack if you have the Ubuntu host, or on command line with driver package plus sample rootfs. If you flash on command line the final command for flash which gives full partition use is:

sudo ./flash.sh -S 14580MiB jetson-tk1 mmcblk0p1

i flashed R21.5, R21.4, R21.3 and R19.2… and followed the instructions to flash the jetson board and did everything as it should be done. The host PC is an Ubuntu 14.04. I also upgraded it to 16.04 and flashed all L4Ts again. It showed no responce.

i doubt it to be a hardware issue. i think Network Manager is responsible for blocking the connection. Because as soon as i log into the jetson, i get a meassage that Network is now disconnected, you are now offline, and when i edit the file interfaces, network manager stops blocking the connection. But it doesnt show any sign of life, i get instead:
failed to send 300 byte long packet over eth0 interface xie 0x215f187a

I tried static IP, also didnt work. So i sent the jetson back to get a new one. I dont have any more time to waste, ive been trying to get it to work for the last 10 days!

Thank you for your help. Too bad case was closed without solving it. If anyone encounters the same Problem, then please post what youve done to fix it.

alayan,

Please follow the RMA support for your tk1.

1. Go to http://www.nvidia.com/nvcc
 2. Select “Live Chat” from the options near the top of the page.
 3. Enter your personal information.
 4. Select the appropriate product from the drop-down list (“Tegra” in this case).
 5. Submit the request.

Hello i have this problem, What is the answer or the solution? Please

Start at the beginning…which networking are you speaking of: Wired versus WiFi. When does it disappear, and which one disappears? Is it after a GUI login, or after a text or network login? FYI, if something changes after a GUI login, then it is probably just NetworkManager configuration thinking you want to switch connection type.
