  2. In the SSH session
    , add the driver to auto load:
    depmod -a echo "tcc_buffer" > /etc/modules-load.d/tcc_buffer.conf
  3. Load the driver:
    modprobe tcc_buffer
Confirm the Real-Time Configuration Driver
The following steps show how to confirm that the real-time configuration driver is loaded:
  1. From your host system, connect to the target system:
    ssh <user>@<target>
  2. In the SSH session
    , run the following command to check whether the driver is loaded:
