Re: [ECOS] RedBoot + Configuration tool 2.11 question

["G.Muruganandam" <gmuruga at gdatech dot com>]

Hi Jonathan,

I have tried the redboot with the tool chain the Intel has tested with.

Now I am seeing the different address for the CMD_TAB. I have pasted below the
out put of the command below.

xscale-elf-nm redboot.elf


00040870 D __RedBoot_CMD_TAB_END__
00040780 D __RedBoot_CMD_TAB__
00040964 D __RedBoot_IDLE_TAB_END__
00040960 D __RedBoot_IDLE_TAB__
00040970 D __RedBoot_INIT_TAB_END__
00040964 D __RedBoot_INIT_TAB__

It looks same as yours.

Now the redboot boots through half way and stops at a point in main.c in 
/packages/redboot/version/src


 for (init_entry = __RedBoot_INIT_TAB__; init_entry != 
&__RedBoot_INIT_TAB_END__;  init_entry++) {
        printf("Init_entry %x, %x \n",init_entry,&__RedBoot_INIT_TAB_END__ );
      (*init_entry->fun)();
======================  hanging point
        mon_write_char(0x34);
    }


I have included a debug statements and printed the value for the table 
addresses after commenting the line
(*init_entry->fun)();

Init_entry 40964, 40970
4Init_entry 40968, 40970
4Init_entry 4096c, 40970


But if the statement (*init_entry->fun)() is there then the system hangs at 
the function pointer line.

Please let me know  what is the function,  function pointer should point to?

Could you please go through and let me know your thoughts.

regards
G.Muruganandam
