about do_bootm_linux in cmd_bootm.c

i used u-boot to run kernel,and it only stoped at "starting kernel...",so i add some prinft command in cmd_bootm.c as follow:

do_bootm()
{
....
switch (hdr->ih_os) {
default: /* handled by (original) Linux case */
case IH_OS_LINUX:

#ifdef CONFIG_SILENT_CONSOLE
	    fixup_silent_linux();

#endif
printf("befor do_bootm_linux \n"); \\added by myself
do_bootm_linux (cmdtp, flag, argc, argv,
addr, len_ptr, verify);
printf("after do_bootm_linux \n"); \\added by myself
break;
}

do_bootm_linux()
{...

	void	(*kernel)(bd_t *, ulong, ulong, ulong, ulong);
        printf("enter the do_bootm_linux \n");
	image_header_t *hdr = &header;

}

but i run get as follow
......

befor do_bootm_linux

Starting kernel ...

so if it can not run to printf("enter the do_bootm_linux \n"), where it puts the "Starting kernel ..."

thanks for any hints

As usual with messages that don't include any information about processor architecture, board name, U-Boot version or anything like that you should not expect a really useful reply.

...

So you obviously modified the wrong code in the wrong source file. There are at leats 8 files which implement the do_bootm_linux() function, depending on which processor you are using.

Also note, that your problem has probably NOTHING to do with U-Boot at all. Read the FAQ.

No, I'm not going to explain it. If you  can't  figure  it  out,  you
didn't want to know anyway... :-)
