Beagle Board XM problem loading a program in the DSP

Hi all,

I'm not much experienced with the TI tools and I have difficulties to load a .out file into the DSP of the Beagle Board. The ARM contains a Linux Kernel booted by U-Boot and I want to execute and debug a small program with the DSP using the CCS environment.

I use :

- Beagle Board -xM OMAP3530 (ARM cortex A8 and DM3730)

- JTAG Emulator XDS510+ USB

- CCS 3.3 (I tried also with the 4 version, but it didn't go very well, the OnTargetConnect() GEL function didn't work.)

I succeed to connect with the ARM and the DSP, I use the IVA2.2 GEL file startup function to release the C64x+ processor from reset like it is informed here :

http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/46697.aspx

I open the C64x+ processor in CCS and realize a small CCS project with a main.c who does an addition and I write the .cmd file below :

-stack 800
-heap 800

MEMORY
{
   IRAM:      o=0x87800000 l=0x5fffff
}
  
SECTIONS
{
  .off_chip   > IRAM
  .bss        > IRAM
  .far        > IRAM
  .chip_image > IRAM
  .data       > IRAM
  .text       > IRAM
  .cio        > IRAM
  .cinit      > IRAM
  .boot       > IRAM
  .const      > IRAM
  .stack      > IRAM
  .sysmem     > IRAM
}

I choose this memory range according to the physic address of the DDR2 :

I build and when I load the program, I receive "data verification error message" on the selected address range.

Does exist a special configuration or mapping for the DSP program memory when the ARM has a Linux kernel inside?

Have anybody ever done this kind of operation?

Thank you for your attention.
