problem with the FLASH SECOND BOOT using BIOS/DSP

[[email protected]]

HI everyone
i have written my code with the help of TI document"Creating a
Second-Level Bootloader for Flash Bootloading on C6000"

the .cmd for linking:
-l testcfg.cmd
SECTIONS
{
.boot_load :> BootRam
}


the .cmd for HEX tranform:
test.out
-a
-image
-zero
-memwidth 8
-map testBIOS.map
-boot
-bootorg 0x90000400
-bootsection .boot_load 0x90000000
ROMS
{
FLASH:org=0x90000000,len=0x0040000,romwidth=8,file s={testBIOS.hex}
}

The problem is when converting COFF to HEX it gives:
"hextest.cmd", line 9: WARNING: invalid option: -bootsection
"hextest.cmd", line 9: FATAL ERROR: cannot open input file
'.boot_load': No such

file or directory (aborting)

WHY??
HOW CAN I SOVLE THIS PROBLEM?
if remove the -bootsection option there is no problem but the
..boot_load cannot be loacated in most front of the HEX file.


somebody give me help plz~~
