Mkprom2 & Rtems

[Martínez, Pablo]

I have been working on the following checks... What do you think?

1) Memory configuration on Target:

  mig0      Aeroflex Gaisler  Xilinx MIG DDR3 Controller
            AHB: 40000000 - 80000000      /*RAM SPACE [I'M NOT USING SRAM]*/
            APB: 80000400 - 80000500
            SDRAM: 1024 Mbyte


2) PROGRAM RUNING IN RAM:

grmon2> load /home/publico/facundo/mem_prom_rtems
  40000000 .text                    130.8kB / 130.8kB   [===============>]
100%
  40020B50 .data                      4.4kB /   4.4kB   [===============>]
100%
  40021D00 .jcr                         4B              [===============>]
100%
  Total size: 135.25kB (93.91kbit/s)
  Entry point 0x40000000
  Image /home/publico/facundo/mem_prom_rtems loaded

grmon2> run

  Program exited normally.

grmon2> mem -ascii 0x400a0000 20
  0x400a0000  55555555  55555555  55555555  55555555    UUUUUUUUUUUUUUUU
  0x400a0010  55555555                                  UUUU

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

3) Build the prom.out (for PROM):

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

NOTE: "mem_prom_rtems is the code that I have loaded in Ram"



4) PROGRAM LOAD IN FLASH (PROM)

grmon2> flash unlock all
  Unlock complete

grmon2> flash erase all
  Erase in progress
  Block @ 0x07ff8000 : code = 0x80  OK
  Erase complete

grmon2> flash load /home/publico/facundo/prom.out
  00000000 .text                     84.8kB /  84.8kB   [===============>]
100%
  Total size: 84.81kB (76.08kbit/s)
  Entry point 0x0
  Image /home/publico/facundo/prom.out loaded

grmon2>

5) (after Reset)

grmon2> mem -ascii 0x400a0000 20
  0x400a0000  40acbebf  78171d5a  e7c78a5b  db3ddfe3    @...x..Z...[.=..
  0x400a0010  e67aeb3c                                  .z.<


Is for that reason that I know why the program is not running. This code
(without Rtems)has been working perfectly using sparc-elf-gcc and mkprom2.
