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
}
