From 6c9b804d6187edda4f46f8458deec0b17ec76bb9 Mon Sep 17 00:00:00 2001 From: ntfreak Date: Sat, 29 Dec 2007 13:51:48 +0000 Subject: - minimum autoconf 2.59 is now required and verified - due to issues with AS_HELP_STRING - native win32 now handles WSAECONNRESET - no longer exits openocd - qCRC packet now works correctly under cygwin (gdb compare-sections command) - removed __USE_GNU define from gdbserver.c - gdb qSupported packet is now handled, with this we are able to tell gdb packet size, memory map of target - added new target script gdb_program_config - called before gdb flash programming - new gdb server command gdb_memory_map (enable|disable> - default is disable - new gdb server command gdb_flash_program (enable|disable> - default is disable - gdb flash programming supported - vFlash packets - image_elf_read_section now does not clear any remaining data, this was causing the gdb checksum to fail with certain files - reformat of usbprog.c - memory leak in command_print fixed - updated texi doc to include new commands - added gdb programming section to docs git-svn-id: svn://svn.berlios.de/openocd/trunk@246 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- src/target/image.c | 41 ++++++++++++++++------------------------- src/target/target.c | 7 +++++++ src/target/target.h | 2 ++ 3 files changed, 25 insertions(+), 25 deletions(-) (limited to 'src/target') diff --git a/src/target/image.c b/src/target/image.c index bdd89b1c..173fca56 100644 --- a/src/target/image.c +++ b/src/target/image.c @@ -360,12 +360,12 @@ int image_elf_read_headers(image_t *image) return ERROR_FILEIO_OPERATION_FAILED;
