+# Installation j1939 for AGL
+
+#### Minimum kernel version : 4.19
+
+## Compilation of kernel j1939
+
+##### Clone linux-can-next repository on kernel.org
+
+```bash
+git clone https://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next.git/
+```
+
+##### Checkout on j1939 branch
+
+```bash
+git checkout j1939
+```
+
+##### Add the compilation of the j1939
+
+```bash
+make menuconfig
+       - Networking Support
+               - Can bus subsystem support
+                       - <M> SAE J1939
+                       - [*]   debug SAE J1939
+```
+
+##### Compile
+
+```bash
+make
+```
+
+##### Install
+
+```bash
+make modules_install
+make install
+```
+
+##### Update grub
+
+###### CentOS/RHEL/Oracle/Scientific and Fedora Linux
+
+```bash
+grub2-mkconfig -o /boot/grub2/grub.cfg
+grubby --set-default /boot/vmlinuz-...
+reboot
+```
+
+###### Debian/Ubuntu Linux
+
+```bash
+update-grub
+reboot
+```
+
+##### Check if the installation is correct
+
+```bash
+modprobe can-j1939
+```
+
+If no errors are generated you have successfully install a kernel with j1939 module.
+
+You can have a problem with header file, to check that go in the file /usr/include/linux/can.h
+
+```bash
+vi /usr/include/linux/can.h
+```
+
+If in the struct sockaddr_can you don't see j1939, the header are not upgrade.
+
+So you need to do this manually, go to you're linux-can-next repository and do the following command:
+
+```bash
+cp include/uapi/linux/can.h /usr/include/linux/can.h
+cp include/uapi/linux/can/j1939.h /usr/include/linux/can/
+```
