Patch from Emmanuel Raguet <raguet@crf.canon.fr> to add remote debug server
and RPC support to RTEMS. Thanks. :) Email follows:
Hello,
For Xmas, here is the Remote Debugger on RTEMS !
Here are 2 patches for the Remote Debugger on RTEMS for pc386 from Linux
host :
- one for RTEMS it self,
- one for GDB-4.17.
1/ RTEMS patch
--------------
This patch adds 2 libraries :
- a simplified SUN RPC library
- the Remote Debugger library
The configuration command is the following :
../rtems4/configure --target=i386-rtemself --enable-rtemsbsp=pc386
--enable-rdbg
The SUN RPC library is built only if networking is set.
The RDBG library is built if networking and enable-rdbg are set.
The function used to initialize the debugger is :
rtems_rdbg_initialize ();
A special function has been created to force a task to be
in a "debug" state : enterRdbg().
The use of this function is not mandatory.
2/ GDB-4.17 patch
-----------------
This patch create a new RTEMS target for GDB-4.17.
The configuration command is the following :
./configure --enable-shared --target=i386RTEMS
To connect to a target, use :
target rtems [your_site_address]
Then, attach the target using : attach 1
And... Debug ;)
You can obtain the original GDB-4.17 on
ftp://ftp.debian.org/debian/dists/stable/main/source/devel/gdb_4.17.orig.tar.gz
This has been tested from a Debian 2.0.1 linux host.
