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,
NULL,
NULL,
(uint32_t*) (&input_ivt),
(uint32_t*) (&__hab_data),
0,
(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.
