hab api is waiting ....

[samet-san]

Hello 

I use hab.c and hab_rvt.c files in  below link.  hab.c has a function that called imx_hab_authenticate_image().  It calls  hab_Entry() function. 

But it is waiting in the entry() function as loop. It cannot continue. 

is there anyone to help me ?

https://github.com/nxp-mcuxpresso/sbl/blob/master/component/secure/semifunc/hab.c

This is my code. 

   LOG_INFO("HAB Entry");

	if (hab_Entry() != HAB_SUCCESS) {
		LOG_ERROR("Error: hab entry function\n");
		goto hab_exit;
	}

    LOG_INFO("Check target");

	status = hab_rvt_check_target(HAB_TGT_MEMORY, (void *)image_start, bytes);
	if (status != HAB_SUCCESS) {
		LOG_ERROR("HAB check target status %x, image_start 0x%08x, end 0x%08x\n", 
               status, image_start, image_start + bytes);
		goto hab_exit;
	}

 
Output :

07.01.2025 16:36:29.096 #1 [15573][INF][UPDATE_HAB:156]PAR : 0x45

I've got a similar problem with a imx8-mini. Where would I confirm the value of HABRVT_API_TREE_ADDR my device? I've looked in the processor reference manual but I'm struggling to find it in the > 5000 pages

[Omar_Anguiano]

Even if HAB is not enabled it is possible to call hab_entry(). Please make sure that the HAB_API address is the correct for the used device.

//RT1170
#define HABRVT_API_TREE_ADDR (0x00211C0C)

Please use this part of code to test the hab_entry:

#include "hab.h"

PRINTF("\n\n\rCalling HAB entry...");
HabStatus = hab_Entry();
PRINTF("\n\rHAB Entry Status = ");
DUMP(&HabStatus,4);

uint32_t habversion;
habversion = hab_Get_version();
PRINTF("\r\n\n HAB version is =%X", habversion);

Best regards,
Omar

I use HAB address that defined in hab_rvt.c file in github link. It is correct. Also HAB is enable.

Also I tried other functions.(report_status etc) But situation didnt change.
