| + | ===== Overview ===== | ||
| + | First, read [[embedded_systems: | ||
| + | |||
| + | The Acontis Stack (Class B) and the DCM Add On (Class A) can be placed anywhere. | ||

| + | ===== LinkLayer Module ===== | ||
| + | - The EC LinkLayer module (kernel module) has to be compiled against the installed linux kernel. If the kernel changes, the module has to be rebuilt and reloaded. | ||
| + | - The loaded standard Ethernet driver (the driver is a Linux kernel module) has to be unloaded after boot. | ||
| + | - The EC LinkLayer has to be loaded after boot. | ||

| + | |||
| + | This is because the stack version is not compatible with the installed kernel. | ||
| + | |||
| + | The Acontis stack V2.9 is compatible with the linux kernel v4.4 but not mit kernel v4.14. | ||

| + | To automate unbinding the standard driver and loading the EC LinkLayer module you can add the following lines to the .bashrc | ||
