Mkprom2 & Rtems

[Martínez, Pablo]

Hello all,

following many posts and documentations on this group and Gaisler support,
I have proved many configurations about loading a Rtems application on PROM.

CODE:
// The following code write many memory address with the same value

#include <stdio.h>
#include <stdlib.h>

#define CONFIGURE_INIT
#define CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER
#define CONFIGURE_MAXIMUM_TASKS             4
#define CONFIGURE_RTEMS_INIT_TASKS_TABLE
#define CONFIGURE_EXTRA_TASK_STACKS         (3 * RTEMS_MINIMUM_STACK_SIZE)


#define CONFIGURE_INIT
#include "system.h"


rtems_task Init(
  rtems_task_argument argument
)
{

    unsigned *mem1;
    int i;

    mem1 = 0X400a0000;

    for (i=0; i<200; i++)
    {

    (*mem1) = 0x55555555;
    mem1++;
    }

exit(0);
}

----------------------------------------------------

I Could implement and run in flash (PROM) the code without Rtems (using:
sparc-elf-gcc and mkprom2)

Now, I need implement the code with Rtems, for that reason I have compiled
the below code with:

 sparc-rtems-gcc and/or sparc-rtems4.10-gcc In both case I can create the
"executable" using Rtems Sparc and Rtems Toolchain on Eclipse.those
implementations have been proved on target (Xilinx Kintex KC-705) and they
run perfect.

Now, I need to have this code in PROM. for that reason I did the following
steps:

1) Created the ".exe" file with Rtems Toolchain on Eclipse
2) Created the prom.out using mkprom (with many configurations)

mkprom2 -msoft-float -ramsize 1024000 -nosram -sdram 1024 -romsize 128000
-romwidth 16 -freq 50 -baud 83400 -rmw -ccprefix sparc-rtems mem_prom_rtems

I can generate the "prom.out" but is not working on the target.... (flash
erase all; flash load prom.out, flash lock all)

Could somebody give me an explanation about what I'm doing wrong?, or give
me an advice to create the prom.out successfully?

Regards,
