# This script is intended for use with separately linked ROM and RAM.
|
||
|
|
# It creates EITHER a linker script that satisfies references made by RAM
|
||
|
|
# applications to ROM symbols OR a linker script that forces symbols to
|
||
|
|
# be included in a ROM image.
|
||
|
|
#
|
||
|
|
# The option "--addrs" causes the RAM linkage script to be generated
|
||
|
|
# and the option "--externs" causes the ROM linkage script to be generated.
|
||
|
|
#
|
||
|
|
# Example usage:
|
||
|
|
# make_ld.sh --addrs sw.rom.out rom.symbols > rom.addrs.ld
|
||
|
|
# make_ld.sh --externs rom.symbols > rom.externs.ld
