ARM Compiler toolchain Using the Linker - ARM Information Center

9.7 Example GNU ld script for linking an ARM Linux executable
GNU ld script support in armlink
The following ld script is sufficient to link a “hello world” application. The most important parts
are:
• The initial . = 0x00008000 + SIZEOF_HEADERS;
The linker can include the ELF Header and Program Header into the first page.
• The alignment expressions that force the RW into a separate page.
• The output sections for the metadata needed by the dynamic linker.
Use the armlink --linker_script command-line option to specify an ld script file.
