Adding new command using existing commands

Hi,

I am trying to add one command in U-Boot using set of existing commands.

e.g. adding one command for fusing flash with a newly compiled file. new command - "fuse_uboot"

used commands:
1. ping (do_ping() call)
2. tftp (do_tftpb() call)
3. protect off (do_protect() call)
4. erase (do_flerase() call)
5. cp.b (do_cp_mem() call)
6. protect on (do_protect() call)
7. reset (do_reset)

I am copying a section of my code:
addition in common/cmd_mem.c:

extern int ping_extern(cmd_tbl_t *cmdtp, int flag, int argc, char * const
argv[]);
extern void protect_extern(cmd_tbl_t *cmdtp, int flag, int argc, char * const
argv[]);
extern int erase_extern(cmd_tbl_t *cmdtp, int flag, int argc, char * const
argv[]);
static int do_mem_cp(cmd_tbl_t *cmdtp, int flag, int argc, char * const
argv[]);

#if defined(FUSE_UBOOT_FILE)
static int do_fuse_uboot(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[])

{
        int ret = 0, ret1 = 0, ret2 = 1;
        unsigned int f_size = 0;

        char *ping_argv[] = {"ping", NULL, NULL, NULL};
        char *tftp_argv[] = {"tftp", NULL, NULL, NULL};
        char *protect_argv[] = {"protect", NULL, NULL, NULL};
        char *erase_argv[] = {"erase", NULL, NULL, NULL};
        char *cp_argv[] = {"cp.b", NULL, NULL, NULL};

        printf("Fusing U-Boot\n");

        ping_argv[1] = getenv("serverip");
        ret = ping_extern(cmdtp, 0, 2, ping_argv);
        if (ret == 0)
        {
                tftp_argv[1] = "10000";
                tftp_argv[2] = "uboot_new.bin";
                ret1 = (do_tftpb(cmdtp, 0, 3, tftp_argv));
                f_size = getenv("filesize");
                if (ret1 == 0)
                {
                        protect_argv[1] = "off";
                        protect_argv[2] = "1:0-10";
                        protect_extern(cmdtp, 0, 3, protect_argv);

                        erase_argv[1] = "1:0-10";
                        ret2 =  erase_extern(cmdtp, 0, 2, erase_argv);

                        if (ret2 == 0)
                        {
                                cp_argv[1] = "10000";
                                cp_argv[2] = "fe000000";
                                cp_argv[3] = f_size;
                                do_mem_cp(cmdtp, 0, 4, cp_argv);

                                protect_argv[1] = "on";
                                protect_argv[2] = "1:0-10";
                                protect_extern(cmdtp, 0, 3, protect_argv);
                                do_reset(NULL, 0, 0, NULL);
                        }
                        else
                                printf("Flash not erased : ERROR %d\n", ret2);
                }
                else
                        printf("FILE NOT FOUND\n");
        }
        else
                printf("PING FAILED : CHECK NETWORK PARAMETERS !!!\n");

        return 0;
}

U_BOOT_CMD(

        fuse_boot, 1, 0, do_fuse_uboot,
        "fuse uboot file from your TFTP server",
        ""

);
#endif

addition in common/cmd_flash.c:

int erase_extern(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[])

{
        int ret;
        ret = do_flerase(cmdtp, 0, 2, argv);
        return ret;
}

void protect_extern(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[])

{
        do_protect(cmdtp, 0, 3, argv);
}

addition in common/cmd_net.c:

int ping_extern(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[])

{
        int ret;
        ret = do_ping(cmdtp, 0, 2, argv);
        return ret;
}

The problem I am facing: whenever I pass "1:0-10" as protect_argv[2], after calling protect_extern(), erase get only "1" as erase_argv[1]. Same goes with every values, if arguments are same for both the call second value gets corrupted.

please help me out !!!

Thanks in advance,
Ajanta
