Example of placing ARM C library code

| Home > Using scatter files > Example of placing ARM C library code | |||
The following example shows how to place C library code:
Example 31. Placing ARM C library code
ROM1 0
{
* (InRoot$$Sections)
* (+RO)
}
ROM2 0x1000
{
*armlib/c_* (+RO) ; all ARM-supplied C library functions
}
ROM3 0x2000
{
*armlib/h_* (+RO) ; just the ARM-supplied __ARM_*
; redistributable library functions
}
RAM1 0x3000
{
*armlib* (+RO) ; all other ARM-supplied library code
; for example, floating-point libraries
}
RAM2 0x4000
{
* (+RW, +ZI)
}
The name armlib is used to indicate the
ARM C library files that are located in the install_directory\lib\armlib
