Hello matthias!
Just take one of the
C:\MSPGCC\msp430\lib\ldscripts\msp430x???.x
files an modify it your way.
Not forgetting to tell the linker about the new file
with sth. like "-T $(NAME).lnk"
This is the easy part ... explaining how to edit the ldscript without
insight into the language itself is far more complicated.
Add your lines to the MEMORY bracket. Like:
irq_handler_ptr (rwx) : ORIGIN = 0x0200, LENGTH = 0x0002
IAR_REGDATA(rw) : ORIGIN = 0x1200, LENGTH = 0x0400
.. and match up the rest in case of length and start addresses.
In the SECTIONS bracket there are blocks like this
.irq_handler_ptr :
{
. = ALIGN(2);
*(.irq_handler_ptr)
} > irq_handler_ptr
.IAR_REGDATA :
{
*(.IAR_REGDATA)
. = ALIGN(2);
*(.IAR_REGDATA.*)
} > IAR_REGDATA
...to be added.
Maybe you need to move them around a little. Somewhere before the
block for "vectors" could be a good point.
Generating the mapfile with ld might be a good idea "-Map $(NAME).map"
to verify locations.
More info about this "language" - if you happen to find any - is
welcome.
In general, if your going for flash, try to c&p the vectors block
because this is a section in flash separated from the "test" section.
Regards,
Helmut
