imx28 hab No HAB Events Found

1.I am use BitInit.exe burn OtpInit.sb and the bit_setting.txt like below

*chip-family-mx28*

lock_rom0 = true

lock_cryptodcp = true

lock_cryptodcp_alt = true

2. useing Mfgtool programming updater_ivt.sb, the imx28 serial port output

3. The display event code like below:

typedef hab_status_t hab_rvt_report_event_t (hab_status_t, uint32_t, uint8_t* , size_t*);

#define HAB_RVT_REPORT_EVENT (*(uint32_t*) 0xFFFF8B18)

#define hab_rvt_report_event ((hab_rvt_report_event_t*)HAB_RVT_REPORT_EVENT)

hab_status_t g_hab_status;

void display_event(uint8_t *event_data, size_t bytes)

{

uint32_t i;

if ((event_data) && (bytes > 0))

{

for (i = 0; i < bytes; i++)

{

if (i == 0)

{

printf(" 0x%02x", event_data[i]);

}

else if ((i % 8) == 0)

{

printf("\n 0x%02x", event_data[i]);

}

else

{

printf(" 0x%02x", event_data[i]);

}

uint8_t event_data[128];

void get_hab_status(void)

{

uint32_t index = 0;

size_t bytes = sizeof(event_data);

uint8_t no_events = 1;

while ((g_hab_status = hab_rvt_report_event(HAB_FAILURE, index, event_data, &bytes))

== HAB_SUCCESS)

{

//no_events = 0;

//break;

no_events = 0;

printf("\n");

printf("--------- HAB Event %d -----------------\n", index + 1);

printf("event data:\n");

display_event(event_data, bytes);

printf("\n");

bytes = sizeof(event_data);

index++;

}

if(no_events)

{

/* Including input_ivt here is simply to force the linker to include

* it in the image and do not optimize it away.

printf("No HAB Events Found! %d\n", input_ivt.ivt.reserved2);

}

else

{

printf("Some HAB Events Found!\n");

}

I don't know why is No HAB Events Found? Is my OtpInit.sb not enable HAB? thanks
