C5510 Application doesn't work after FlashBurn with .cinit allocated in SDRAM

Hi all,

I am using a Spectrum Digital TMS320VC5510 DSK board to develop an application. The application, after FlashBurn to the onboard FlashROM, runs OK if I allocate the Data Initialization Section (.cinit) in the SARAM(or SARAM_A/_B) via the GUI BIOS/DSP Config interface. However if I allocate the .cinit section in SDRAM and FlashBurn to the FlashROM, it does not work (or boot). In the Linker option, I have tried both the Run-Time Autoinitialization (-c) and the Load-Time Initialization (-cr); the results are same.

My application has to use the SDRAM for .cinit allocation. Did I miss something or something in my linker and hex55 option is wrong?

I have used the following Hex55 options in the convert command file:

myApplication.out
-m2
-boot
-map myApplicationHex.map
-parallel16
-v5510:2
-o myAPplication.hex

ROMS {
PAGE 0 : ROM : o=0x400000 , l = 0x80000
}

Thanks for you help.

Regards,

U need to add some config EMIF regs code in HEX55 convert, examples:

-reg_config 0x6c00, 0x0001 /* Enable EMIF bus. */
-delay 0x100
-reg_config 0x0800, 0x00e0 /* EMIF_GCTL1 */
-delay 0x100
-reg_config 0x0804, 0x4210 /* EMIF_CE01 */
-delay 0x100
-reg_config 0x0805, 0x1092 /* EMIF_CE02 */
-delay 0x100
-reg_config 0x0802, 0x0410 /* EMIF_CE11 */
-delay 0x100
-reg_config 0x0803, 0x0155 /* EMIF_CE12 */
-delay 0x100

myApplication.out
-m2
-boot
-map myApplicationHex.map
-parallel16
-v5510:2
-o myAPplication.hex

ROMS {
PAGE 0 : ROM : o=0x400000 , l = 0x80000
}
