I am attempting to use an Arduino with my TX2 and it is not showing up under /dev/ttyACM* and after some research discovered it may because of the lack of an ACM driver. I have attempted to install this using JetsonHack’s tutorials on building the kernel to include modules and have been getting errors each time that I attempt to make the kernel. I am on 4.4.15-tegra.
The following is the output from
./makeKernel.sh 1>/dev/null
showing only the errors.

Once I run that, trying to run
./copyImage.sh
results in
cp: cannot stat 'arch/arm64/boot/Image': No such file or directory
Any assistance with this would be greatly appreciated!
I can’t say for sure, but it seems you may have started with a configuration which has some sort of conflict. What did you use for the initial configuration? I recommend copy of “/proc/config.gz”…this is a reflection of the configuration of the running kernel produced by the kernel itself. Starting there and then adding the ACM driver would be the most reliable way to begin.
@Kangalow I tried both versions vL4T27.1 and vL4T28.1 just to make sure and had no success either time. I also just re-tried the L4T 27.1 tutorial you have for this and changed the local version to “-tegra” and ran makeKernel.sh with 1>/dev/null. This was the output of running this specifically.

I apologize, I’ve got two devices I am working with. The one that was on 27.1 is not going to be used. The device we will be using is on L4T R28.1 and uname -r results in
4.4.38-tegra-leopard
We are using a custom board from Leopard Imaging if that makes any difference.
I will re-try running the kernel rebuild process for 28.1 and check back with the results.
