TDA4VM: tiovx initialization stability fault

user6136340

Part Number: TDA4VM

tiovx appinit function and appdeinit fuction could not work normally after repeate 125times.

TI's code:
int32_t appInit()
{
    int32_t status = 0;

    status = appCommonInit();

    if(status==0)
    {
        tivxInit();
        tivxHostInit();
    }
    return status;
}
int32_t appDeInit()
{
    int32_t status = 0;

    tivxHostDeInit();
    tivxDeInit();
    appCommonDeInit();

    return status;
}

my application code:

for(int r = 0; r < 128; r++){
        appInit();

        if (status != 0) {
            printf("appInit failed !!!\n");
            return -1;
        } else {
            printf("appInit success !!!\n");
        }
        printf("run times :%d\n", r);

        appDeInit();
    }

always out of order in 127 times!!!!!!!!!!!!!!!!!!

Hello,

I have a few questions for you to help me with an answer:

1. Which release of the Processor SDK are you using?

2. I assume in your code, you are setting status equal to appInit and appDeInit when running?

3. Can you send your full log of all the iterations? I assume that this is the first failure, correct?

I tried running this with our upcoming release and I do not see this issue. There have been some improvements made and this may have fixed this issue.

Regards,

Lucas

1. SDK : psdk_rtos_auto_j7_07_00_00_11

2. i have setted status:

for(int r = 0; r < 128; r++){

status = appInit();

if (status != 0) {

printf("appInit failed !!!\n");

return -1;

} else {

printf("appInit success !!!\n");

}

printf("run times :%d\n", r);

appDeInit();

}

3. first failure occurs in 126（counter start from 0） times and then always fall in fault。

Hello,

I tried this on my end with the release you described and I am not seeing this issue. Can you confirm that you have not made any changes to the SDK beyond adding this test case?

Regards,

Lucas
