Hello,
Could you please advice a common way to allocate a larger variable?
Is it neccesary to edit MEMORY directive in a *.CMD file?
volatile Uint16 abc[0x1100];
The size of the array abc[] is 0x1100 words.
My customer would like to allocate the array at RAMGS5 (Addr=0x11000).
With no edit of *.CMD, linker error was generated:
<Linking>
"../2837xD_RAM_lnk_cpu1_edit.cmd", line 70: error #10099-D: program will not
fit into available memory. run placement with alignment/blocking fails for
section ".ebss" size 0x110d page 1. Available memory ranges:
RAMGS5 size: 0x1000 unused: 0xff6 max hole: 0xff6
RAMGS6 size: 0x1000 unused: 0x1000 max hole: 0x1000
RAMGS7 size: 0x1000 unused: 0x1000 max hole: 0x1000
error #10010: errors encountered during linking;
"blinky_cpu01_edit02_Linker_01.out" not built
>> Compilation failure
makefile:151: recipe for target 'blinky_cpu01_edit02_Linker_01.out' failed
gmake: *** [blinky_cpu01_edit02_Linker_01.out] Error 1
gmake: Target 'all' not remade because of errors.
The linker error was cleared by the following *.CMD edit to prepare a larger memory range:
#define EDIT 1
MEMORY
{
..
PAGE 1 :
#if EDIT // successful
RAMGS5 : origin = 0x011000, length = 0x003000
#else// original
RAMGS5 : origin = 0x011000, length = 0x001000
RAMGS6 : origin = 0x012000, length = 0x001000
RAMGS7 : origin = 0x013000, length = 0x001000
#endif
..
}

We are working on the SPRU513 8.5.5.6 ~ 8.5.5.7.
8.5.5.6 Allocation Using Multiple Memory Ranges
~ To allocate whole a section into a named memory range.
8.5.5.7 Automatic Splitting of Output Sections Among Non-Contiguous Memory Ranges
~ To allow splitting a section to fit.
