Part Number: DRA74

Tool/software: TI-RTOS

As gudie to compile then run the app.out. has an error. VSDK0305.

Could you give me some suggestions? thanks.

    Hi Widic,

    You would need to perform the follow changes:

    1. In vision-SDK please make the following modifications in the apps/src/tda2xx_evm_linux_all/cfg.mk file
    IVAHD_ENABLE=no
    IPUMM_ENABLE=no
    PROC_IPU2_INLCUDE=no

    PROC_IPU1_0_INCLUDE=yes

    PROC_IPU1_1_INCLUDE=no

    IPU_PRIMARY_CORE=ipu1_0
    IPU_SECONDARY_CORE=ipu2

    Perform a clean-build after these changes.

    2. With the above changes, only the Vision-SDK firmware is built. The IPU-MM firmware needs to be sepearately built -- instructions to which can be found here:
    processors.wiki.ti.com/.../Processor_Training:_Multimedia

    3. In the Linux kernel device-tree, please make the following modifications:

    &ipu1 {
    status = "okay";
    };

    &ipu2 {
    reg = <0x0 0x95800000 0x0 0x38000000>;
    };

    Recompile Linux after these changes.

    Regards
    Shravan

    Hi Widic,

    It looks like there's issue with the IPUMM firmware load.
    Can you also add the below line to your kernel DTB and see if it works.

    &ipu2{
    timers= <&timer3>;
    };

    Also, support for early-boot+late-attach on the IPUMM firmware isn't supported. So please make sure IPUMM firmware is being boot-strapped only from Linux and not from u-boot.

    Regards
    Shravan
