Apply patch

Autonomous Machines Jetson & Embedded Systems Jetson Nano
1

Hello,

I’m trying to follow instructions of this topic to fix I2S pins configuration on the Jetson Nano.

The problement is that I’m stuck at the step apply patch.

I’m trying to follow the documentation to reboot the kernel but I get the following error when I try to run the script “apply_binaries.sh”:

user@user-desktop:~/Documents/Linux_for_Tegra$ sudo ./apply_binaries.sh
Using rootfs directory of: /home/user/Documents/Linux_for_Tegra/rootfs
find: ‘/home/user/Documents/Linux_for_Tegra/rootfs/etc/passwd’: No such file or directory

2. The root filesystem, provided with this package,

   /home/user/Documents/Linux_for_Tegra/rootfs
-----------------------------------------------------
Consult the Development Guide for instructions on
extracting and flashing your device.

Is this the correct process to apply a patch on Jetson Nano ?
If so, where do this error come from ?

Thanks in advance.

The apply_binaries.sh is not exactly a patch. What it does is add NVIDIA content to an otherwise purely Ubuntu filesystem. However, you have not installed the software this is applied to.

If you had used JetPack/SDK Manager, then this would be installed for you (including the application of those drivers).

If you manually install, then it goes like this:

  • Unpack the driver package as a regular user without sudo.
    (this produces the Linux_for_Tegra/ directory)
  • Go to the Linux_for_Tegra/rootfs/ subdirectory and unpack the sample rootfs with sudo.
  • Go back to Linux_for_Tegra/ and run “sudo ./apply_binaries.sh”

From that point forward you can flash using command line (you don’t need to repeat the above steps).

The above is not a patch. This is for a full flash. I don’t know if this fixes a problem or not, but if you have an older release, then that is possibly the case.

Incidentally, L4T is what one calls Ubuntu once the NVIDIA drivers are present (this is what apply_binaries.sh does). An older Nano is compatible with L4T R32.x. See this to get the most recent release:
https://developer.nvidia.com/linux-tegra

Usually a release of JetPack is also tied to a given L4T release, so picking one usually picks the other.

The apply_binaries.sh is not running on Jetson Nano device itself…

The actual process is as linuxdev just mentioned. You need another x86 ubuntu host to develop and flash the jetson nano. “apply_binaries.sh” is running on that x86 host but not your jetson directly.

u must have kernel sources (sources in C language)
then u must modify gpio-tegra.c file in text editor add some lines to it at specific places

then build kernel with make command

and then transfer kernel image and modules to jetson usin flash command through usb cable

Thanks for your answers !

I manage to create the appropriate Linux_for_Tegra package.

Now I’m in the process of flashing the board, but once I execute the flash command:

user@Ubuntu20:/media/user/sedondaryDisk/Linux_for_Tegra$ sudo ./flash.sh jetson-nano-devkit mmcblk0p1

the process stop at the step

Do you know where this bug comes from ?
I’m using a VirtualBox Ubuntu, I know it isn’t ideal but it’s all I have.

Same problem with a default Linux_for_Tegra repository, found this link dealing with BootRom is not running problem.
If I can manage to get a Linux computer I’ll try to flash and update the topic.

During flash the USB will disconnect and reconnect. Your VM is failing to recognize reconnect. The actual flash software has no control over this, so you’d have to find out how to adjust the VM to always own that USB.
