Tool/software: Code Composer Studio
Hi,
I use CCS5.2.1, and my board is TMS570LS3137, I creating a library file(Testlib.lib), and I add the Testlib.lib into project A, and built OK.
now, the problem is：
I have some global variable in the Testlib.lib file, if I initialize these global variables when I define them , and after built the project, these global variables will be mapped in the ram area(0x08000000-0x0803FFFF) of TMS570LS3137.
but , if if I do not initialize these global variables when I define them , and after built the project, these global variables will be mapped in the flash area(0x00000000-0x002FFFFF) of TMS570LS3137.
because there are many do not initialized global variables when I define them ,and I do not want to change the code, and I want these global variables be mapped in ram area(0x08000000-0x0803FFFF) in TMS570LS3137.
how can I do?
my .CMD file is :
MEMORY{
VECTORS (X) : origin=0x00000000 length=0x00000020
FLASH0 (RX) : origin=0x00000020 length=0x0007FFE0

Thank a lot!
