8.28 Example of placing ARM C library code 8.28.1 See also The following example shows how to place C library code: Using scatter files Example 8-19 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 armlib directory. The location of armlib is defined by the ARMCC41LIB environment variable.
