BDM interface for MPC823

Building GDB for FreeBSD 6.2

• Download files:

  	from http://www.erwinrol.com/index.php?opensource/bdm.php
  		mpc8xx-0.0.3.tar.gz
  		mpc8xx-0.0.3-gdb-6.1.1-p0.patch.gz
  	from http://ftp.gnu.org/gnu/gdb/
  		gdb-6.1.1.tar.gz
  

• Create build directory:

  	# cd ....
  	# mkdir gdb_mpc8xx
  	# cd gdb_mpc8xx
  

• Build libmpc8xx:

  	# tar xvzf ..../mpc8xx-0.0.3.tar.gz
  	# cd libmpc8xx
  	** replace malloc.h by stdlib.h in libmpc8xx/mpc8xxflash.c
  	** remove sys/io.h from libmpc8xx/lptbdm.c
  	** replace ioperm by i386_set_ioperm in libmpc8xx/lptbdm.c
  	** double line 480 (pvr = mpc8xx_get_spr( .. ) in libmpc8xx/mpc8xxspr.c
  	# ./configure
  	# gmake
  

• Test libmpc8xx:

  	** connect BDM interface to LPT0
  	# example/mpc8xx 0 2 0
  

  The output of mpx8xx should contain:

  	Target cpu PVR=0x00500000 PARTNUM=0x21 MASKNUM=0x01 REV_NUM=0x0001
  

• Install libmpc8xx:

  	# gmake install
  

• Build GDB for MPC8XX:

  	# cd ..../gdb_mpc8xx
  	# tar xvzf ..../gdb-6.1.1.tar.bz2
  	# patch < ..../mpc8xx-0.0.3-gdb-6.1.1-p0.patch
  	# mv mpcbdm.h mpcbdm.c gdb-6.1.1/gdb
  	# rm mpcbdm.?.orig
  	# cd gdb-6.1.1
  	# ./configure --target=powerpc-linux --enable-mpc8xx \
  		--with-mpc8xx-lib-dir=/usr/local/lib \
  		--with-mpc8xx-include-dir=/usr/local/include
  	** remove "wait.h" and "sys/io.h" includes from gdb/mpcbdm.c
  	# gmake (ignore warnings)
  

• Test GDB:

  	# gdb/gdb -x ..../cc1000.gdb_init
  	gdb> x/16i 0xfff00100
  	gdb> quit
  

  cc1000.gdb_init contains the adapter and memory initialization for the CC1000.
  
  
• Install GDB:

  	# gmake install
  

  gdb gets renamed to 'powerpc-linux-gdb' during install
