TMS320F2800157: Linker will not include .const section

Part Number: TMS320F2800157

Hi,

I'm new to fitting everthing into a defined part of Flash using the linker script.  I've got an TMS320F2800157 LaunchPad that the application needs to run from flash. 

The current linker script is below and I admit I've hacked it together to get this far.   My desire is to contain all the application in Flash and I don't feel that I need to control how it is stored in flash.  I am writing a bootloader running from RAM that can reflash it , but I plan just to wipe all of flash at once.  Thus I think I'm ok just handling all of flash as one block.

Using the script below, I'm getting the following error:

../280015x_generic_flash_lnk.cmd", line 28: warning #10097: memory range not found: FLASH_BANK0_SEC_127 on page 1
../280015x_generic_flash_lnk.cmd", line 28: error #10265: no valid memory range available for placement of ".const"
../280015x_generic_flash_lnk.cmd", line 28: error #10099-D: program will not fit into available memory, or the section contains a call site that requires a trampoline that can't be generated for this section. placement with alignment/blocking fails for section ".const" size 0x1db6 page 1

Linker script below:

}

I've looked at the map file and found that the highest address used in flash is 00090268 and the flash extends to 0x9FFFF.  The .const segment needs 00001dc0.  How do I tell the linker to just add it to the block of flash?

Thanks in advance,

John
