From 237e894805dd757cc24029af1b4b1e824c51712b Mon Sep 17 00:00:00 2001 From: drath Date: Tue, 29 May 2007 11:23:42 +0000 Subject: - split fileio handling into fileio part and image handling - reworked etm/etb into a generic etm part with trace capture drivers (currently only etb supported) - added XScale debug handler binary to repository - added Thumb disassembling (thanks to Vincent Palatin for this patch) - added support for non-CFI compatible flashes to cfi driver (currently only SST39VFxxx devices supported) This checkin is experimental, not suitable for general use git-svn-id: svn://svn.berlios.de/openocd/trunk@155 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- src/flash/non_cfi.c | 175 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 175 insertions(+) create mode 100644 src/flash/non_cfi.c (limited to 'src/flash/non_cfi.c') diff --git a/src/flash/non_cfi.c b/src/flash/non_cfi.c new file mode 100644 index 00000000..3a74ff92 --- /dev/null +++ b/src/flash/non_cfi.c @@ -0,0 +1,175 @@ +/*************************************************************************** + * Copyright (C) 2007 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.
