<h4 class="subsection">1.1.2 Motorola CPU32 Targets supported</h4>
|
|
<p>This refers to Motorola’s m68k based CPU32 processor family. The crt0.S
|
|
startup file should be usable with any target environment, and it’s
|
|
mostly just the I/O code and linker scripts that vary. Currently there
|
|
is support for the Motorola MVME line of 6U VME boards and IDP
|
|
line of eval boards. All of the
|
|
Motorola VME boards run <code>Bug</code>, a ROM based debug monitor.
|
|
This monitor has the feature of using user level traps to do I/O, so
|
|
this code should be portable to other MVME boards with little if any
|
|
change. The startup file also can remain unchanged. About the only thing
|
|
that varies is the address for where the text section begins. This can
|
|
be accomplished either in the linker script, or on the command line
|
|
using the ‘<samp>-Ttext [address]</samp>’.
|
|
</p>
|
|
<p>There is also support for the <code>rom68k</code> monitor as shipped on
|
|
Motorola’s IDP eval board line. This code should be portable across the
|
|
range of CPU’s the board supports. There is also GDB support for this
|
|
target environment in the GDB source tree. The relevant files are
|
|
gdb/monitor.c, monitor.h, and rom58k-rom.c. The usage of these files is
|
|
discussed in the GDB section.
