TDA4VM: provided MCUSW mcu2_1 software for CAN can not be extended

Mircea Cociuba
Intellectual 655 points

Part Number: TDA4VM

Hello Tarun,

As we start working on mcu2_1 using the mcusw baseline you provided, something came up.

We moved the IPC application that we had from pdk mcu3_0 ( modifyng the makefiles of course), to mcusw mcu2_1, and now the Linux will not boot:

We copied the linker, and only the linker for now, the transceiver patch for linux not yet.

with not other changes except the linker, the linux booted.

    Hi,

    We copied the linker, and only the linker for now, the transceiver patch for linux not yet.

    Ween you want to use CAN, you need transceiver patch for Linux & u-boot.

    You can integrate the IPC to CAN example in a separate thread and use it.

    Best Regards,
    Sudheer

    I do not want to use the CAN for now, just the IPC :), incremental stuff you know. we have the baseline ( which does not work, we know that), now we add the IPC and linker, to have it run.

    Untill the tresos license arrives, the CAN part is useless as the projects baud-rate is 500k.

    Hello Mircea,

    Thanks for raising another thread.

    First of all, your EB tresos license request has been approved.

    If you want to shift PDK IPC to MCUSS Demos(Can profile test) , you need to understand better on the work flow of IPC .The reserved areas and resource table of MCU3_0  will be completely different from MCU2_1.I am not sure what exactly you shifted and of course copying the API's of PDK MCU3_0 are definitely not going to help on MCU2_1.This is going to be a altogether a different development.In my opinion if you are on mcusw ,preferrable to use CDD IPC(same PDK IPC) but different API's.

    If it helps we have CDD IPC Rproc Linux application which runs baremetal on MCU2_1 and communicates with A72 in mcusw.
