From: drath Date: Fri, 11 Aug 2006 17:49:41 +0000 (+0000) Subject: - added support for FreeBSD ppi (parallel port access similar to /dev/parport on... X-Git-Tag: v0.1.0~1163 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=ec0f06db114d1cc9d1d59acd8f4e3b32414d5b8e;p=openocd - added support for FreeBSD ppi (parallel port access similar to /dev/parport on linux) (thanks to Darius for this patch) - unified 'ftd2xx' and 'ftdi2232' into a single interface 'ft2232'. The library used to access the hardware is choosen during configure with --enable-ft2232_ftd2xx or --enable-ft2232-libftdi. git-svn-id: svn://svn.berlios.de/openocd/trunk@83 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- diff --git a/configure.in b/configure.in index 3518b38d..e2e9adec 100644 --- a/configure.in +++ b/configure.in @@ -24,13 +24,13 @@ AC_ARG_ENABLE(parport_ppdev, AS_HELP_STRING([--enable-parport_ppdev], [Enable use of ppdev (/dev/parportN) for parport]), [parport_use_ppdev=$enableval], [parport_use_ppdev=no]) -AC_ARG_ENABLE(ftdi2232, - AS_HELP_STRING([--enable-ftdi2232], [Enable building the libftdi ft2232c driver]), - [build_ftdi2232=$enableval], [build_ftdi2232=no]) +AC_ARG_ENABLE(ft2232_libftdi, + AS_HELP_STRING([--enable-ft2232_libftdi], [Enable building support for FT2232 based devices using the libftdi driver]), + [build_ft2232_libftdi=$enableval], [build_ft2232_libftdi=no]) -AC_ARG_ENABLE(ftd2xx, - AS_HELP_STRING([--enable-ftd2xx], [Enable building the ftd2xx ft2232c driver]), - [build_ftd2xx=$enableval], [build_ftd2xx=no]) +AC_ARG_ENABLE(ft2232_ftd2xx, + AS_HELP_STRING([--enable-ft2232_ftd2xx], [Enable building support for FT2232 based devices using the FTD2XX driver]), + [build_ft2232_ftd2xx=$enableval], [build_ft2232_ftd2xx=no]) AC_ARG_ENABLE(amtjtagaccel, AS_HELP_STRING([--enable-amtjtagaccel], [Enable building the Amontec JTAG-Accelerator driver]), @@ -114,16 +114,16 @@ else AC_DEFINE(BUILD_BITBANG, 0, [0 if you don't want a bitbang interface.]) fi -if test $build_ftdi2232 = yes; then - AC_DEFINE(BUILD_FTDI2232, 1, [1 if you want libftdi ft2232.]) +if test $build_ft2232_libftdi = yes; then + AC_DEFINE(BUILD_FT2232_LIBFTDI, 1, [1 if you want libftdi ft2232.]) else - AC_DEFINE(BUILD_FTDI2232, 0, [0 if you don't want libftdi ft2232.]) + AC_DEFINE(BUILD_FT2232_LIBFTDI, 0, [0 if you don't want libftdi ft2232.]) fi -if test $build_ftd2xx = yes; then - AC_DEFINE(BUILD_FTD2XX, 1, [1 if you want ftd2xx ft2232.]) +if test $build_ft2232_ftd2xx = yes; then + AC_DEFINE(BUILD_FT2232_FTD2XX, 1, [1 if you want ftd2xx ft2232.]) else - AC_DEFINE(BUILD_FTD2XX, 0, [0 if you don't want ftd2xx ft2232.]) + AC_DEFINE(BUILD_FT2232_FTD2XX, 0, [0 if you don't want ftd2xx ft2232.]) fi if test $build_amtjtagaccel = yes; then @@ -139,8 +139,8 @@ AM_CONDITIONAL(PARPORT, test $build_parport = yes) AM_CONDITIONAL(GIVEIO, test $parport_use_giveio = yes) AM_CONDITIONAL(EP93XX, test $build_ep93xx = yes) AM_CONDITIONAL(BITBANG, test $build_bitbang = yes) -AM_CONDITIONAL(FTDI2232, test $build_ftdi2232 = yes) -AM_CONDITIONAL(FTD2XX, test $build_ftd2xx = yes) +AM_CONDITIONAL(FT2232_LIBFTDI, test $build_ft2232_libftdi = yes) +AM_CONDITIONAL(FT2232_FTD2XX, test $build_ft2232_ftd2xx = yes) AM_CONDITIONAL(AMTJTAGACCEL, test $build_amtjtagaccel = yes) AM_CONDITIONAL(IS_CYGWIN, test $is_cygwin = yes) AM_CONDITIONAL(IS_MINGW, test $is_mingw = yes) diff --git a/src/Makefile.am b/src/Makefile.am index 2647fd5e..208041f1 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -16,7 +16,7 @@ else MINGWLDADD = endif -if FTDI2232 +if FT2232_LIBFTDI FTDI2232LIB = -lftdi else FTDI2232LIB = @@ -32,7 +32,7 @@ else FTD2XXLDADD = -lftd2xx endif -if FTD2XX +if FT2232_FTD2XX FTD2XXLIB = $(FTD2XXLDADD) else FTD2XXLIB = diff --git a/src/jtag/Makefile.am b/src/jtag/Makefile.am index bb9337aa..ec46111e 100644 --- a/src/jtag/Makefile.am +++ b/src/jtag/Makefile.am @@ -25,16 +25,16 @@ else PARPORTFILES = endif -if FTDI2232 -FTDI2232FILES = ftdi2232.c +if FT2232_LIBFTDI +FT2232FILES = ft2232.c else -FTDI2232FILES = +FT2232FILES = endif -if FTD2XX -FTD2XXFILES = ftd2xx.c +if FT2232_FTD2XX +FT2232FILES = ft2232.c else -FTD2XXFILES = +FT2232FILES = endif if AMTJTAGACCEL @@ -49,6 +49,6 @@ else EP93XXFILES = endif -libjtag_a_SOURCES = jtag.c $(BITBANGFILES) $(PARPORTFILES) $(FTDI2232FILES) $(FTD2XXFILES) $(AMTJTAGACCELFILES) $(EP93XXFILES) +libjtag_a_SOURCES = jtag.c $(BITBANGFILES) $(PARPORTFILES) $(FT2232FILES) $(AMTJTAGACCELFILES) $(EP93XXFILES) noinst_HEADERS = bitbang.h jtag.h diff --git a/src/jtag/ft2232.c b/src/jtag/ft2232.c new file mode 100644 index 00000000..64975825 --- /dev/null +++ b/src/jtag/ft2232.c @@ -0,0 +1,1228 @@ +/*************************************************************************** + * Copyright (C) 2004, 2006 by Dominic Rath * + * Dominic.Rath@gmx.de * + * * + * This program is free software; you can redistribute it and/or modify * + * it under the terms of the GNU General Public License as published by * + * the Free Software Foundation; either version 2 of the License, or * + * (at your option) any later version. * + * * + * This program is distributed in the hope that it will be useful, * + * but WITHOUT ANY WARRANTY; without even the implied warranty of * + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
