AM5728: RPMSG example for bare metal

Dirk Zenker
Intellectual 700 points
Part Number: AM5728

Hallo,

we have bare metal applications on DSP1 and IPU1_0 on the AM5728. Both are communicating with each other via mailbox and executing real time tasks. And both are startet from Linux per remoteproc.

Actuallay we have some problems with the communication to the Linux tasks via rpmsg.

Are there any bare metal examples of rpmsg on DSP1? Or other bare metal examples for communication between Linux and DSP1 (via shared memory e.g. userio)?

Thank you.

    Hello Dirk,

    I'm not aware of any bare-metal examples for inter-processor communication with the Arm running Linux but let me check internally and get back to you.

    Hello Dirk,

    Wanted to confirm that we do not have any bare-metal examples available. Note from the IPC developer:

    "The ARM Linux rpmsg stack is agnostic of the OS running on the remoteproc. As long as the library can support the proper rpmsg stack initialization on the remote-side we should be fine.

    I am not aware of any readymade bare-metal stacks that we have on AM572x."
