|
||
|
|
<p>The Crt0 startup file should run on any mips target that doesn’t require
|
||
|
|
additional hardware initialization. The I/O code so far only supports a
|
||
|
|
custom LSI33k based RAID disk controller board. It should easy to
|
||
|
|
change to support the IDT line of eval boards. Currently the two
|
||
|
|
debugging protocols supported by GDB for mips targets is IDT’s mips
|
||
|
|
debug protocol, and a customized hybrid of the standard GDB remote
|
||
|
|
protocol and GDB’s standard ROM monitor support. Included here is the
|
||
|
|
debug stub for the hybrid monitor. This supports the LSI33k processor,
|
||
|
|
and only has support for the GDB protocol commands <code>g</code>, <code>G</code>,
|
||
|
|
<code>m</code>, <code>M</code>, which basically only supports the register and
|
||
|
|
memory reading and writing commands. This is part of libgloss and is
|
||
|
|
called lsi33k-stub.c.
|
||
|
|
</p>
|
||
|
|
<p>The crt0.S should also work on the IDT line of eval boards, but has only
|
||
|
|
been run on the LSI33k for now. There is no I/O support for the IDT eval
|
||
|
|
board at this time. The current I/O code is for a customized version of
|
||
|
|
LSI’s <code>pmon</code> ROM monitor. This uses entry points into the monitor,
|
||
|
|
and should easily port to other versions of the pmon monitor. Pmon is
|
||
|
|
distributed in source by LSI.
