ISSUE REGARDING PPA Fetch FOR NAND BOOT

Hi,

I am currently working on ls1043ardb board.In the reference board the ppa is fetched from NOR location(60500000) by default(for all boot modes). I am trying to change the ppa address for nand that is ,if i am booting from nand it should take ppa from nand itself.

I have modified the following files:

1=>include/configs/ls1043ardb.h

2=>arch/arm/cpu/armv8/fsl-lsh2/ppa.c

The modifications are given below:

1=>

#ifdef CONFIG_NAND_BOOT

#define CONFIG_SYS_LS_PPA_FW_IN_NAND

#ifdef CONFIG_SYS_LS_PPA_FW_IN_NAND

#define CONFIG_SYS_QE_FW_IN_NAND

#define CONFIG_SYS_LS_PPA_FW_ADDR       0x220000

#endif

#else

#define CONFIG_SYS_LS_PPA_FW_IN_NOR

#ifdef CONFIG_SYS_LS_PPA_FW_IN_NOR

#define CONFIG_SYS_LS_PPA_FW_ADDR       0x60500000

#endif

The above modifications are in file1.

2=>

#if defined(CONFIG_SYS_LS_PPA_FW_IN_NOR)

        fit_hdr = (void *)CONFIG_SYS_LS_PPA_FW_ADDR;

        printf("\nHEader1:%p",fit_hdr);

#elif defined(CONFIG_SYS_LS_PPA_FW_IN_NAND)

        fit_hdr = (void *)CONFIG_SYS_LS_PPA_FW_ADDR;

        printf("\nHeader:%p",fit_hdr);

#else

#error "No CONFIG_SYS_LS_PPA_FW_IN_xxx defined"

#endif

These modifications are in ppa.c

But still i am getting the below given issue:

fsl-ppa: Bad firmware image (not a FIT image)

fsl-ppa: error (-22)

tzc380_init: add 0 regions

tzc380: tzc380_reg_base = 0000000001500000

Whats the issue?Is there any other modifications needed apart from this??

Pls help

Thanks in advance

The LS1043 SDK 0.5 provides loading of the Primary Protected Application (PPA) image using NOR Flash only. Find the following in the ppa.c file:
#ifdef CONFIG_SYS_LS_PPA_FW_IN_NOR
                    fit_hdr = (void *)CONFIG_SYS_LS_PPA_FW_ADDR;
#else
#error "No CONFIG_SYS_LS_PPA_FW_IN_xxx defined"
#endif

Hi Pavel,

Is there any way to change the ppa.c so as to fetch ppa from NAND???

I have done the following modifications in ppa.c:

if defined(CONFIG_SYS_LS_PPA_FW_IN_NAND)

  nand_info_t nand_info[CONFIG_SYS_MAX_NAND_DEVICE];

  size_t fw_length = CONFIG_SYS_QE_FMAN_FW_LENGTH;

  void *fit_hdr = malloc(CONFIG_SYS_QE_FMAN_FW_LENGTH);

  rc = nand_read(&nand_info[0], (loff_t)CONFIG_SYS_LS_PPA_FW_ADDR,

                       &fw_length, (u_char *)fit_hdr);

        if (rc == -EUCLEAN) {

                printf("NAND read of PPA  at offset 0x%x failed %d\n",

                        CONFIG_SYS_LS_PPA_FW_ADDR, rc);

       }

But it seems like it does not work.Is there any other way to do it?

Pls help

Hi,

I'm not an u-boot or PPA guru, but as far I know no matter where you boot, the PPA firmware is loaded from NOR currently.

Thank you,

Marius
