I have located the const data for the target source module using #pragma default_section (CONSTDATA, "NewConst"). I have also modified the LDF to put the first segment of the MEM_SDRAM0_BANK1 area into a new memory segment called MEM_SDRAM_BANK1A, and have placed "NewConst" into that area using a new section definition block. This all works just fine, and my linker map shows the const allocations for this module properly placed in the expected memory locations. However, when I examine this area at runtime, it is filled with 0's rather than the const data. There are no warnings or errors at link time.
