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
