Hello everyone,
Can you tell exactly how you followed the instruction to modify DTB?
I followed the instruction however it mainly covers on how to compile the new kernel while as far as I understand this, the need is to alter the file within hardware folder and not the kernel itself (considering that kernel_src consists of the following two folders: hardware and kernel)
Would appreciate any direction on this matter.
Yes, i had to change in hardware folder. When i build the kernel, changes were effective and new kernel-4.9/kernel_build/arch/arm64/boot/dts/tegra210-p3448-0000-p3449-0000-b00.dtb was created.
Looks like nvidia has modified the kernel to build. So, give it a try with kernel build.
Thanks ganga. I did the part with building the kernel, now i got stuck how to flash it, can you advise how did you do it?
I have complied the kernel on the actual nano…
I have used external Host to build an image, after the kernel build, i copied Image and dtb into Linux_for_Tegra and used a script file to create the sd-card image.
Commands used:
$TEGRA_KERNEL_OUT/arch/arm64/boot/Image – <release_packagep>/Linux_for_Tegra/kernel/Image
cp ./arch/arm64/boot/Image …/…/…/…/Linux_for_Tegra/kernel/Image
$TEGRA_KERNEL_OUT/arch/arm64/boot/dts/ – Linux_for_Tegra/kernel/dtb/
cp -R ./arch/arm64/boot/dts/ …/…/…/…/Linux_for_Tegra/kernel/dtb/
sudo ./apply_binaries.sh
And then created a sd-card image with script,
sudo ./create-jetson-nano-sd-card-image.sh -o sd-blob-b01.img -s 10G -r 300
Thanks ganga. Managed to get it done and also overcome the problem with Wifi.
Few remarks though:
Basically followed the following when it comes to building the kernel:
https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3231/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fkernel_custom.html%23
and this one in order to flash my image:
Although had to overcome few obstacles along the road: in the NVIDIA guide name of script is different, also had to download few files in addition like L4T Driver package and Sample root file system.
Nevertheless, achieved what i needed after few hours.
Cheers.
I finally got around to trying the fix today! it worked like a charm. I have to say that figuring out how to build and flash the DTB and kernel was a pain though… the instructions are not very well written in my opinion. Anyway, for reference here is a step by step:
Required:
Computer with Ubuntu and Jetpack SDK installer, with the Jetson Nano jetpack downloaded
Steps:
On the computer go to the folder where Jetpack is installed
cd ~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_NANO/Linux_for_Tegra
Find the tag for the kernel sources you need. For Jetpack 4.3 it was tegra-l4t-r32.3.1
Use source_sync.sh
script to download the kernel sources, you will be asked for the above tag to download the correct version of the sources
$ ./source_sync.sh
After the above finishes, the source files will be at:
~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_NANO/Linux_for_Tegra/sources
Find the file mentioned in th post above:
Continue building the kernel, set the output folder where you want the new files to be built:
$ TEGRA_KERNEL_OUT=~/KernelBuild
Find the path to. the arm64 toolchain
$ which aarch64-linux-gnu-cpp
the output should be something like: /usr/bin/aarch64-linux-gnu-cpp
Set the variables for cross-compiling, use the output from the above command with. out the cpp
part:
$ export CROSS_COMPILE=/usr/bin/aarch64-linux-gnu-
$ export LOCALVERSION=-tegra
Create the .config
file by executing the following commands:
$ cd ~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_NANO/Linux_for_Tegra/sources/kernel/kernel-4.9
$ mkdir -p $TEGRA_KERNEL_OUT
$ make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_defconfig
Build the Kernel and all DTBs (note <n>
is the number of processors available -1):
$ make ARCH=arm64 O=$TEGRA_KERNEL_OUT -j<n>
Copy the created image and DTBs to the JetPack folder:
$ cp $TEGRA_KERNEL_OUT/arch/arm64/boot/Image ~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_NANO/Linux_for_Tegra/kernel/Image
$ cp -r $TEGRA_KERNEL_OUT/arch/arm64/boot/dts/* ~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_NANO/Linux_for_Tegra/kernel/dtb/
Install the Kernel Modules:
$ sudo make ARCH=arm64 O=$TEGRA_KERNEL_OUT modules_install INSTALL_MOD_PATH=~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_NANO/Linux_for_Tegra/rootfs/
create an archive of. the kernel modules and replace the old ones (replace <yourusername>
with your linux user to set the correct owner of the file) :
$ cd <modules_install_path>
$ sudo tar --owner root --group root -cjf kernel_supplements.tbz2 lib/modules
$ mv ~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_NANO/Linux_for_Tegra/kernel/kernel_supplements.tbz2 ~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_NANO/Linux_for_Tegra/kernel/kernel_supplements.tbz2.orig
$ sudo mv kernel_supplements.tbz2 ~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_NANO/Linux_for_Tegra/kernel/
$ sudo chown <yourusername>:<yourusername> ~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_NANO/Linux_for_Tegra/kernel/kernel_supplements.tbz2
Apply the binaries you just created:
$ cd ~/nvidia/nvidia_sdk/JetPack_4.3_Linux_JETSON_NANO/Linux_for_Tegra
$ sudo ./apply_binaries.sh
At this point you either need to create an SD Card image for the Nano, or in my case I had to flash a production module with the updated kernel using the following command.
$ sudo ./flash.sh -r jetson-nano-emmc mmcblk0p1
After this is done follow the normal initial configuration steps on the Nano and you image will no longer have the issue.
Hope this makes it easier for anyone to modify and rebuild the kernel if needed.
Hi, @Manikanta, could you help with similar issue with QCNFA335?

I tried your solution here and recompile the kernel but it didn’t work.
This seem also has been reported here
Additional info: the first time the image booted and I had to setup the wifi connection in the wizard, it worked. But after it reboots, that error above is shown in dmesg.
Can you execute below script and provide output?
#!/bin/bash
shopt -s nullglob
for g in /sys/kernel/iommu_groups/; do
echo "IOMMU Group ${g##/}:"
for d in $g/devices/; do
echo -e "\t$(lspci -nns ${d##/})"
done;
done;
Thanks,
Manikanta

Hi,
I don’t find AFI as part of iommu group, so the change is not applied correctly. Please follow the steps shared by Jaime and verify.
Thanks,
Manikanta
OK, seems like I needed to do “make clean” before recompiling the kernel.
It’s working, now. Many thanks!
