OMAP-L138 Changing DSPLink Memory Map in DVSDK

kai cheng

When the ARM & DSP starts printing the following information

Error: DSP-side memory map does not match configuration.

Compare DSP-side TCF/MAP file with /dsplink/config/all/CFG_<PLATFORM>.c

PROC_load () failed. Status = [0x80008013]

But configure to RESET_VECT = 0xC2E00000 = 0x00000004 mem=40M Successful start，Other configurations will not work,eg RESET_VECT = 0xC8E00000 = 0x0000ff00

256MB DDR2, has been tested, read and write properly

1. Modify $(...)/ti-dvsdk_omapl138-evm_4_01_00_09/dsplink_1_65_00_02/dsplink/config/all/CFG_OMAPL138GEM_SHMEM.c

· //#define RESETCTRLADDR 0xC2E00000

change to

#define RESETCTRLADDR 0xCEE00000

2. Modify $(...)/ti-dvsdk_omapl138-evm_4_01_00_09/dsplink_1_65_00_02/dsplink/dsp/inc/DspBios/5.XX/OMAPL138GEM/dsplink-omapl138gem-base.tci

//prog.module("GBL").C64PLUSMAR192to223 = 0x00000004 ; change to

prog.module("GBL").C64PLUSMAR192to223 = 0x0000C000 ;

//RESET_VECTOR.base = 0xC2E00000 ; change to

RESET_VECTOR.base = 0xCEE00000 ;

3. On Linux, setenv bootargs mem=224M ….

Are you still seeing same error ("Error: DSP-side memory map does not match configuration.") after making the modifications to memory map ?

Looks like you are doing all the right things.

- What version of DSPLink are you using ? Are you building your own program or one of the DSPLink samples ? Is this a Codec Engine application ?

- Could you also share the DSP map file, the config file, and the DSPLink config file that you have modified and rebuilt the DSP executable with ?

Thanks,

Gunjan.
