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
