bruce_chen — Mon, 20 Jun 2016 01:57:13 GMT

Hello all:

Now I am use Imx28 HAB secure boot, but use Mfgtool programming the imx28_ivt_linux.sb, the imx28 serial port output 0x80501001 DCP， I am check the ROM ERROR Code docment, The 0x80501001 error code is DCP reported a status error. but I don't know how can i made the right imx28_ivt_liunx.sb. accordding to AN4555.pdf doccument like below step:

a、use otp_burner.py create OtpInit.sb file and burner to OTP use imx_otp_tools.

b、Acorrding to AN4555.pdf document create digital signature imx_ivt_linux.sb and updater_ivt.sb files.

c、Copy imx_ivt_linux.sb and updater_ivt.sb to MfgTool.

d、Programming failed and imx28 serial port output ROM error code 0x80501001.

I am use imx-bootlets-src-10.12.01 and I am modify some source code and linker script:

a. add new source file hab_ivt.c, the like content below

#include "hab.h"

struct my_ivt {

uint32_t header;

uint32_t *entry;

uint32_t reserved1;

uint32_t *dcd;

uint32_t *boot_data;

uint32_t *self;

uint32_t *csf;

uint32_t reserved2;

uint32_t img_len;

};

extern char __hab_data;

extern char __hab_data_end;

extern void* _start;

//extern char BASE_ADDR;

#define BASE_ADDRESS 0x40000100

const struct my_ivt input_ivt __attribute__((section(".data"),aligned(4))) = {

0x402000d1,

(uint32_t*) (&_start),

NULL,

(uint32_t*) (&input_ivt),

(uint32_t*) (&__hab_data),

(const void*) (&__hab_data_end) - BASE_ADDRESS,

};

b. modify boot_prep/link.lds script

OUTPUT_ARCH(arm)

ENTRY(_start)

SECTIONS

{

. = 0x00000010;

. = ALIGN(4);

. = 0x40000100;

BASE_ADDR = .;

.text : { *(.text) }

.data : { *(.data) }

. = BASE_ADDR + 0x2A000;

__hab_data = .;

. = . + 0x2000;

__hab_data_end = .;

. = ALIGN(4);

.bss : { *(.bss) }

}

c. Modify the boot_prep/Makefile for compile hab_ivt.c file

I don't know my add the IVT methods is right? please help me thanks.
