TDA4VM: TIDL Demo cause mcu1_0 abnormal

Hi Ding,

Are you able to run any of the vision_apps demo? I would like to know if this is an issue specifically with just the tidl demo application, or the issue is with all the vision_apps demos.

Regards,

Takuma

Hello Ding,

May I know in which SDK version are you seeing this issue?

If MCU1_ 0 runs the demo ipc_echo_testb_mcu1_0_release_strip.xer5f/vx_app_rtos_linux_mcu1_0.out

Do you mean if MCU1_0 runs the demo ipc_echo_testb_mcu1_0_release_strip.xer5f, you are not seeing the issue?

Could you provide the full logs or your observation when the mcu1_0 is getting stuck.

Are there any memory related changes done such as modifying the memory configurations?

Hi Nikhil，

My SDK vision is：

ti-processor-sdk-linux-j7-evm-08_00_00_08-Linux-x86

ti-processor-sdk-rtos-j721e-evm-08_00_00_12

Yes，If I use ipc_echo_testb_mcu1_0_release_strip.xer5f,Everything is ok.

Nikhil said:

No, I didnt do any memory change.

My mcu1_0 is running original mcusw. No extra log output when the mcu1_0 is getting stuck.

Besides，I have a new discovery. When I commented out the following line of code, run tidl demo again, MCU1_ 0 will not get stuck.

status = vxProcessGraph(obj->graph);

This is the default test that would be running in the mcu1_0 that is as provided in the SDK.

May I know which SW or binary are you trying to run on mcu1_0? Is it something from the mcuss_demos or have you created your own mcusw?

If you comment out this line, then the application itself will not run as this line begins the application by starting the graph. This action is similar to not running the tidl application.

Hi Nikhil，

The project paths we use are as follows: /mcusw/mcuss_demos/profiling/cddIpc，And we have modified the project:

1、pdk_jacinto_08_00_00_37/packages/ti/kernel/freertos/config/j721e/r5f/FreeRTOSConfig.h

#define configMAX_PRIORITIES                    (32)

#define configUSE_STATS_FORMATTING_FUNCTIONS    (1)

2、mcusw/mcuss_demos/profiling/cddIpc/overrides/j721e/r5_mpu_freertos.c

Modify the following：

    {

        /* Region 7 configuration: Ring Buffer uncached.... */

        .regionId         = 7U,

        .enable           = 1U,

        .baseAddr         = 0xB0000000,

        .size             = CSL_ARM_R5_MPU_REGION_SIZE_32MB,

        .subRegionEnable  = CSL_ARM_R5_MPU_SUB_REGION_ENABLE_ALL,

        .exeNeverControl  = 0U,

        .accessPermission = CSL_ARM_R5_ACC_PERM_PRIV_USR_RD_WR,

        .shareable        = 1U,

       .cacheable        = (uint32_t)FALSE,

        .cachePolicy      = CSL_ARM_R5_CACHE_POLICY_NON_CACHEABLE,

        .memAttr          = 0U,

    },

Add the following：

    {

        //Region 9 configuration: Covers first 64MB of EVM Flash (FSS DAT0) *

        .regionId         = 9U,

        .enable           = 1U,

        .baseAddr         = 0x97000000,

        .size             = CSL_ARM_R5_MPU_REGION_SIZE_16MB,

        .subRegionEnable  = CSL_ARM_R5_MPU_SUB_REGION_ENABLE_ALL,

        .exeNeverControl  = 0U,

        .accessPermission = CSL_ARM_R5_ACC_PERM_PRIV_USR_RD_WR,

        .shareable        = 0U,

        .cacheable        = (uint32_t)TRUE,

        .cachePolicy      = CSL_ARM_R5_CACHE_POLICY_WB_WA,

        .memAttr          = 0U,

    },

 3、Ported IPC functionality in : mcusw/mcuss_demos/profiling/cddIpcRPocLinux

4、Modify the IPC Ringaddress to 0xB0000000:

CDD_IPC_CONFIG_DATA_SECTION CONST(Cdd_IpcConfigType, CDD_IPC_CONFIG_DATA)

            CddIpcConfiguraions_PC =

{

.........

    .vertIoCfg =

    {

        .vertIoRingAddr = (void *)0xB0000000U,

        /**< Defines address that shall be shared between cores */

        .vertIoRingSize = 0x02000000U,

        /**< Size of the shared memory */

        .reserved = 0U,

        /**< Future use if any */

    },

......

};

5、Added some tasks，mbox，semphore  for KEY, LCD control

Hi Nikhil，

Can you give me some advice on this question？

Hi Ding,

Could you please check if the behavior is the same by just running the cddIpc example?
This way we could narrow down the issue.

Nikhil
