[U-Boot-Users] can gd cause hang in board_init_r?

22 Nov 2005


      in board_init_r(lib_mips/board.c)
i add three serial out lines
       serial_puts("before gd\n");
      printf("gd =%x \n", gd);
serial_puts("after cmd relocate!\n");
sometimes, it only output first line,sometimes the first two lines,
sometimes the three lines are all outputed, are  these caused by gd
operation? or other reasons?
thanks for any hints

my board_init_r as follows
void board_init_r (gd_t *id, ulong dest_addr)

    DECLARE_GLOBAL_DATA_PTR;
    cmd_tbl_t *cmdtp;
    ulong size;
    extern void malloc_bin_reloc (void);

    extern char * env_name_spec;
#endif
    char *s, *e;
    bd_t *bd;
    int i;
serial_puts("before gd\n");
    gd = id;
      printf("gd =%x \n", gd);
    gd->flags |= GD_FLG_RELOC;	/* tell others: relocation done */
//debug ("Now running in RAM - U-Boot at: %08lx\n", dest_addr);
gd->reloc_off = dest_addr - CFG_MONITOR_BASE;
monitor_flash_len = (ulong)&uboot_end_data - dest_addr;
/*
     * We have to relocate the command table manually
     */
    for (cmdtp = &__u_boot_cmd_start; cmdtp !=  &__u_boot_cmd_end; cmdtp++) {
    	ulong addr;

#if 0
    	printf ("Command "%s": 0x%08lx => 0x%08lx\n",
