Reduce boot time tx2

How can I make tx2 boot in less than 25 seconds?
I’m using Jetpack 4.2.1(REV 2) linux for tx2 from the nvidia SDK meneger.
Now it takes about 40 seconds.

I able to reduce boot time by disable the RTC and sound nodes in device tree and now it boots in 35 seconds.

I tried install lighter desktop environment xfce4 but I cannot login into xfce4. Also tried to mask services from systemd-analyze but it didn’t help to reduce boot time.

How can I skip the nvidia logo in boot? it can reduce some time? even if it reduce few seconds it will help allot.

Anyone knows another ways to reduce boot time?

You can refer to Reduce boot time if Jetson TX2

Tnx for the quick reply.

Maybe it will help, I don’t need Wifi but not sure how I can disable it.

more suggestions?

Hi,

Generally, you could dump the serial console log and check how much time is taking in each component.
For example, there is a 5 second count down in uboot and it can be disabled too.

Does your boot time include the boot time of display manager (GUI)?

Here is dmesg but I don’t understand from it how much time is taking in each component

FYI, each numeric entry in that first column is the cumulative time in boot. What you are looking for are sudden jumps in time, rather than tiny increments. So this could be ignored and there is no need to even examine what it does due to short increment in time:

(which you wouldn’t get rid of anyway because it is loading firmware and booting CPU cores)

You’d probably want to ignore anything before this anyway since it is all prior to the init system beginning its real work (so what shows up after 0.87 seconds is what you have more control over):

Now if you go to that point in the log, and just use your mouse scroll wheel to scroll through at some consistent rate, then you might notice larger jumps, for example:

…note that mmc tuning is not something you could avoid, but time to complete scanning PCIe for endpoints is around “3.332381 - 1.700889” seconds (1.631492 sec). If you know you will not have any PCIe devices, then perhaps you could save 1.6 seconds by disabling any attempt to scan PCI. Considering how important PCI is, and how invasive it might be to disable PCI, it is unlikely you’d want to save 1.6 seconds dealing with that. But it illustrates that scanning for devices is significant in time cost.

WiFi was already mentioned elsewhere, and if you don’t need it, then you could disable WiFi. This is simple and common relative to something like PCIe enumeration. In a normal setup loading drivers and firmware for WiFi doesn’t take a lot of time, but if Network Manager is used to bring up or scan for WiFi at the moment of a GUI login, then this latter login overhead would be eliminated if WiFi did not have a driver loaded and basically did not exist as far as the GUI is concerned.

This might seem like a problem, but in reality it is not:

…the time between ending USB setup and GPU is large at “10.718889 - 6.990916” seconds (3.727973 sec), but this is the GPU setting up. Even if you don’t use X/GUI graphics you would still need the GPU to function if you want to use CUDA.

On the other hand you could consider X11 part of the boot time which occurs after the GPU is initialized as something you can control to some extent. You mentioned:

…and this would indeed help if xfce4 takes less time and also actually works. It might be worth pursuing the errors you get trying to log in under xfce4.

This probably could use some elaboration:

…it appears that about a minute after GUI is up the display is going into low power mode from inactivity. This content is irrelevant because presumably the GUI is up and available, but simply timed out after a minute of inactivity. Most of what you are concerned with will occur prior to this unless you are also considering the time it takes to log in to the GUI.

I don’t see any particularly large gaps you can get rid of. If the boot media were faster, then boot would be faster, e.g., a fast SSD instead of eMMC. However, that isn’t trivial.

I didn’t see network setup, but if you did use the network (for example, wired), then using a static address is faster than waiting for a DHCP response from a router (and is also impractical except under private networks).

NVIDIA would have to comment on this, but in some cases where a logo is showing boot is continuing and seeing the logo does not necessarily mean boot has paused while showing the logo. Don’t know for sure, I’d be interested in knowing that myself.

You have not said anything about your use case, and so other than “making it faster” we have no knowledge of what you are trying to accomplish. Maybe if you gave details on what you need to occur and the environment that is booting (e.g., with wired network or not) it might be easier to answer.

Hi,

Here is dmesg but I don’t understand from it how much time is taking in each component

Actually, there are still logs before kernel. That also counts in boot time.

Please dump the serial console log from uart and you will be able to check that.

WiFi was already mentioned elsewhere, and if you don’t need it, then you could disable WiFi…

-No need for wifi/ I connect via ethernet to a private network, however (not internet - another computer)/ I’ve tried disabling/masking the wifi service through the systemctl command, but haven’t noticed a difference. Is there a different/better way to do this?

and this would indeed help if xfce4 takes less time and also actually works. It might be worth pursuing the errors you get trying to log in under xfce4.

-I tryed installing xfce4 but after installed and restart system the login screen dont’ has session option to enter xfce4. Not sure why. Is it posible to set deafult desktop envoirment as xfce4 in Tx2. If so, what is the correct way to do so?

You have not said anything about your use case, and so other than “making it faster” we have no knowledge of what you are trying to accomplish.

Use case: the tx2 is running a single, python-case application with a GUI that includes live video from a USB camera. In addition, it is connected via ethernet to another computer, forming a small network. No need for internet or other programs to run or be open. No connection to wifi or bluetooth, no sound needed. The application is full screen. We were considering getting rid of the desktop environment and installing a windows manager instead. Does this seem like a reasonable direction?

I do not know enough to actually provide details, but gstreamer does have different “sinks” which can be used instead of displaying to the X11 GUI environment. Someone else will need to provide details for this.

Hi Malikov!

There are several tricks to reduce the boot time of your system. The trick is to get rid off what you won´t need for your final application. So, for example if you don´t need Wifi don´t load it. You are on a good way until now by removing unnecessary things. So, you can customize your kernel image by removing drivers for things that you will not need and save some seconds at boot time.

You can get extra time reductions by around 3 seconds by setting the bootcount to 0. Uboot usually waits 3 seconds for any user input to interrupt the boot and enters into bootloder configuration. You can verify this and modify the u-boot environment variable that defines it. You must connect trough the TX2 using a FTDI serial cable over the UART port at connector J21. Take a look at this link for reference: https://www.jetsonhacks.com/2017/03/24/serial-console-nvidia-jetson-tx2/

Based on your use case of just executing a python application with a GUI that displays video from an USB camera at full screen, I will suggest to disable the Ubuntu desktop GUI. This will saves you a lot of time at start up.

You can render directly to the framebuffer of the TX2 and display your application at full screen by using GStreamer nvoverlaysink for example. So, you don’t need a windows manager or anything from the Ubuntu GUI.

Systemd is the main init system. And to disable the X desktop (GUI), need to disable the display manager service. There are different kinds of display managers available (gdm, kdm & lightdm) and TX2 uses lightdm as the display manager. By using systemd we can disable the GUI.

Follow these steps to disable Ubuntu GUI:

  1. Stops the lightdm service:
    sudo systemctl stop lightdm

  2. To permanently remove/disable the Ubuntu desktop GUI load, it is necessary to modify the /etc/systemd/nvfb.sh file, by removing the following line:
    service lightdm restart

  3. Also, you could add the following command on the /etc/rc.local file, so it will be executed automatically on startup:
    sudo systemctl stop lightdm

  4. Another option is to rename or change the permissions of the following file, so the system can’t find it:
    /usr/sbin/lightdm

By just running the above steps, when the ubuntu desktop is disabled a console on the HDMI output appears. That console shows some ubuntu login messages and other log messages. That terminal could be very annoying if you want to run an app on startup and don´t want those messages to be shown before your app is launched.

So, to disable or remove that console you must run the following commands:

Xorg &                # launches the display server
export DISPLAY=:0.0   # Configures the output display

If you want to run an app at startup you could add the above commands and the call to the app script to the /etc/rc.local file. It should be something like that:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

Xorg &
export DISPLAY=:0.0
/home/ubuntu/pipeline.sh &

exit 0

Your application should render directly to the TX2 framebuffer to get something visible at the display, you can easily achieve that by using GStreamer nvoverlaysink element.
