    Hi,

    After dig into ti-recipe,  I've  found "multiprocmgr"  recipe and by adding it into my build I've added "mpmcl " commands.

    but still something I'm missing.

    during my booting TI Multiproc Manager getting  failed and the log i've mentioned below.


    [FAILED] Failed to start TI Multiproc Manager.
    See 'systemctl status mpmsrv-daemon.service' for details.



    when i've checked "systemctl status mpmsrv-daemon.service" , I've got the following log.

    [[0;1;31m●[[0m mpmsrv-daemon.service - TI Multiproc Manager

    ~

    From the log  we can found "Module keystone_remoteproc" not found and it fails.

    due to the failing of "multiproc manager" I'm not able to utilize mpmcl commands.

    Please help me to resolve multiproc manager failure.

    Regards

    You need to make sure that the remoteproc kernel driver is getting built and put into the modules directory as indicated by the modprobe: FATAL output. Kernel modules are usually enabled in your kernel config, and they need to be built and installed separately. The TI SDK includes this module and should be a good reference for you to see how to add it properly to get around this error.

    Thank you.
