<div dir="ltr">Hi all,<div><br></div><div>I can report that using CFLAGS_FOR_TARGET worked. e.g</div><div><br></div><div>CFLAGS_FOR_TARGET+=-qnolinkcmds -T $(exec_prefix)/mrm332/lib/linkcmds_ROM<br></div><div><br></div><div>
Will now use the ROM linker script instead of the RAM linker script which has the default name linkcmds</div><div><br></div><div>Cheers,</div><div>James</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">
