Part Number: AM5728


Tool/software: Linux

when I load dsp1  firmware，I get error message below。Firmware is messageq_single.xe66 from ti。I have linked it to /lib/firmware/dra7-dsp1-fw.xe66 with absolutely path.

dts:

    mboxes = <&mailbox5 &mbox_dsp1_ipc3x>;
    timers = <&timer5>;

    mboxes = <&mailbox6 &mbox_dsp2_ipc3x>;
    timers = <&timer6>;

};

generate by dtc tools is：

        dsp@40800000 {
            compatible = "ti,dra7-dsp";
            reg = <0x40800000 0x48000 0x40e00000 0x8000 0x40f00000 0x8000>;

            ti,hwmods = "dsp1";
            syscon-bootreg = <0x9 0x55c>;
            iommus = <0xc1 0xc2>;

            mboxes = <0xb5 0xc4>;
            timers = <0xc5>;

    Hi, Fei Liang,

    Which release are you using? Is the messageq_single.xe66 from the filesystem in /lib/firmware/ipc/ti_platforms_evmDRA7XX_dsp1?

    I use ProcSDK 4.1 release and don't see any issue with prebuilt images. Please see logs below. Does anything in your run differ from mine?

    thanks for reply.

    I have resolved "DSP watchdog crash".My kernel configure issue.

    I  use sdk04.01.00.06 also ,but it report

    [  204.117119] omap_hwmod: mmu0_dsp1: _wait_target_disable failed

    This kernel message does not report on sdk-03.01.00.06.

    Fei Liang,

    Good to know you fixed your kernel configuration and solve the issue. The message only mean the module mode is not supported and can't be disabled. It is not fatal and the system is operational.
