Internet bonding possible in jetson nano ?

I need to create a internet bonding using two 4g dongle with interface wwan0 and wwan1. I followed many tutorial but nothing helped. So can anyone know how to do it in jetson nano. Because im new to this board. i installed ubuntu os with jetpack using official jetson nano page.

I don’t have experience on 4G dongle. Could you share your current status and what have you tried?

After google search i found that have to recompile the kernel with bonding driver.I followed this one for recompile kernel for bonding driver. so,i followed the link:https://devtalk.nvidia.com/default/topic/1047880/jetson-tx1/mount-network-folder-samba-cifs/post/5322451/#5322451. But , i stuck in “make -j4 O=$TEGRA_KERNEL_OUT Image” command with the below error.

The way to build kernel is in the L4T document. Please refer to L4T document for the steps.

I followed this https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fkernel_custom.html%23wwpID0ESHA l4t documentation.

Im failed to getting .ko file in this module directory

Did you read “Preparing to Build External Kernel Modules” section?

I followed the tutorial but i had doubt in some lines . so can you guys give a exact steps for building ethernet bonding module driver in jetson

I proceeded from the above section. After i finished with the end command of “make ARCH=arm64 -C TEGRA_KERNEL_OUT M=(pwd)” , i didn’t got any error and i got only three files without bonding.ko file.

It will be great if someone can share the bonding.ko file if you have it prebuilt. I am sure it is going to be easier for the Nvidia devs to give us the bonding.ko file for jetson nano. This has been delaying our software development on the Jetson nano for over two weeks now.

I am confused by your log here.

First, why do you build you source in the header src? There is no kernel source at all. Did you download the source from our download center?
Second, do you enable CONFIG_BONDING in tegra_defconfig?

Thanks to WayneWWW for pointed my mistake. Now bonding module builded successfully.
I followed the below code. It will be helpful for someone who stucked like me.

sudo ./source_sync.sh -k tegra-l4t-r32.1

sudo -s

cd /usr/lib/$(uname -r)/

rm build

ln -s /usr/src/sources/kernel/kernel-4.9/ build

cd /usr/src/sources/kernel/kernel-4.9/

sudo -s

cp /proc/config.gz .

gunzip config.gz

mv config .Config

# Edit and make sure you have CONFIG_LOCALVERSION="-tegra" #(i skipped this one)

make nconfig

make modules_prepare

cd drivers/net/bonding/

​make ARCH=arm64 -C /lib/modules/4.9.140-tegra/build M=$(pwd)

exit
