Re: memory allocation | Analog Devices DSPs

Technical discussions related to Analog Devices DSPs (including Blackfin, TigerSHARC, SHARC and ADSP-21xx DSPs).

Hello again, Good news, I got the debugger running with some help from the folks at tech support. it WAS the registry. Go fig... Anyway, now I'm trying to convert a C-program over to assembler and see if maybe I can streamline it a little. However, I get the following errors. [Error E2007] Out of memory in memory segment "seg_dmda". While processing the input section "seg_dmda" from file "INT_TABL.DOJ" of size 0x50a words [Error E2007] Out of memory in memory segment "seg_dmda". While processing the input section "seg_dmda" from file "DOPRNT.DOJ" of size 0x30c words [Error E2007] Memory allocation errors. See the MAP file ".\DEBUG\PLAY_FILE.map" for details those would lead me to believe that I ran out of memory in one of the sections on the chip. However, when I look at the memory map file that the compiler referred me to (one generated by the compile itself, not the generic one) it says that I still have unused blocks of memory in each section. One of them gets pretty close, but there are still 0x26 available. Am I not looking at the right thing? Tom Hanley

"seg_dmda" is the name of the section in an object or executable file. (Object and executable section names in different name spaces, but the ADI conventions typically use the same names for both. I use different names in my LDF files, using seg_* for object files, out_* for executables, and mem_* for memory regions, to make the error messages easier to figure out.) The LDF describes the partitioning of memory and which memory section to place each object section in. The first (memory) section of the LDF file associates a memory section name with an address space, specified by its starting address, length, width, and type. The second LDF section associates an executable section name with a memory section name, and specifies, for each object file, which object sections go in that executable section.
