How to integrate kernel-module in yocto-dunfell? #yocto #dunfell #apt #tx2 #kernel
|

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. I would really appreciate any help !

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. marek |

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,marek |

Shared recipe should be the same as one from meta-oe :). So you can include it in your image and it should be build then.
