Hey community,

I'm trying to use this library [can-isotp][1] on a Jetson TX2 Board. The version of the running OS is: 0.0.8 (dunfell).

From the docs of the library I get the following instructions:

```

DOWNLOAD and BUILD

1. Download repository and enter the repositories root directory

git clone https://github.com/hartkopp/can-isotp.git

cd can-isotp

2. Build ISO-TP kernel module

Ensure build dependencies are installed. E.g. for Debian (or Ubuntu):

sudo apt-get install build-essential linux-headers-$(uname -r)

To build:

(you need to be in the repositories root path)

make

To install (optional):

sudo make modules_install


3. When the PF_CAN core module is loaded ('modprobe can') the ISO-TP module
can be loaded into the kernel with

insmod ./net/can/can-isotp.ko

When the can-isotp.ko module has been installed into the Linux Kernels
modules directory (e.g. with 'make modules_install') the module should
load automatically when opening a CAN_ISOTP socket.

```

I have some questions about that procedure. Can anybody give me an hint on how to install this module? Do I have to create a completly new yocto image or is there any way to install kernel modules afterwards? I tried to copy the folder onto the TX2 and install it by hand, but (as to be expected) the make command is not found.

PLease take a look at :
https://www.yoctoproject.org/docs/2.6/kernel-dev/kernel-dev.html#working-with-out-of-tree-modules
where it is described how to compile out of tree modules.

in this case you might be lucky we already have recipe
http://cgit.openembedded.org/meta-openembedded/tree/meta-oe/recipes-extended/socketcan/can-isotp_git.bb?h=master
its blacklisted because it needs work to fix build on 5.2+ kernel

I would really appreciate any help ! Best regards,
