From 3acb107b9ae4e3d38d3fcfd29b455ebcfb444696 Mon Sep 17 00:00:00 2001 From: drath Date: Thu, 31 Aug 2006 12:41:49 +0000 Subject: - endianess fixes everywhere but in the flash code. flashing might still be broken on big-endian targets and/or hosts - added access to ARM920T vector catch register (via generic register mechanism) - don't disable linefills on ARM920T cores - this lead to lockups when accessing lines already contained in cache - read content of ARM920T cache and tlb into file (arm920t read_flash/read_mmu commands) - memory reading improved on ARM7/9, can be further accelerated with new "arm7_9 fast_memory_access enable" command (renamed from fast_writes) - made in_handler independent from in field (makes the handler more flexible) - added timeout to ft2232 when using D2XX library - fixed STR7x protection bit handling on second bank (thanks to Bernard) - added support for using the OpenOCD on AT91RM9200 systems (thanks to Anders Larsen) - fixed AT91SAM7 flash handling when not running from 32kHz clock (thanks to Anders Larsen) git-svn-id: svn://svn.berlios.de/openocd/trunk@90 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- src/target/arm_jtag.c | 86 +++++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 83 insertions(+), 3 deletions(-) (limited to 'src/target/arm_jtag.c') diff --git a/src/target/arm_jtag.c b/src/target/arm_jtag.c index ccc1adf4..3bb8a32f 100644 --- a/src/target/arm_jtag.c +++ b/src/target/arm_jtag.c @@ -108,11 +108,91 @@ int arm_jtag_setup_connection(arm_jtag_t *jtag_info) return ERROR_OK; } +/* read JTAG buffer into host-endian u32, flipping bit-order */ int arm_jtag_buf_to_u32_flip(u8 *in_buf, void *priv) { u32 *dest = priv; - - *dest = flip_u32(buf_get_u32(in_buf, 0, 32), 32); - + *dest = flip_u32(le_to_h_u32(in_buf), 32); + return ERROR_OK; +} + +/* read JTAG buffer into little-endian u32, flipping bit-order */ +int arm_jtag_buf_to_le32_flip(u8 *in_buf, void *priv) +{ + h_u32_to_le(((u8*)priv), flip_u32(le_to_h_u32(in_buf), 32)); + return ERROR_OK; +} + +/* read JTAG buffer into little-endian u16, flipping bit-order */ +int arm_jtag_buf_to_le16_flip(u8 *in_buf, void *priv) +{ + h_u16_to_le(((u8*)priv), flip_u32(le_to_h_u32(in_buf), 32) & 0xffff); + return ERROR_OK; +} + +/* read JTAG buffer into big-endian u32, flipping bit-order */ +int arm_jtag_buf_to_be32_flip(u8 *in_buf, void *priv) +{ + h_u32_to_be(((u8*)priv), flip_u32(le_to_h_u32(in_buf), 32)); + return ERROR_OK; +} + +/* read JTAG buffer into big-endian u16, flipping bit-order */ +int arm_jtag_buf_to_be16_flip(u8 *in_buf, void *priv) +{ + h_u16_to_be(((u8*)priv), flip_u32(le_to_h_u32(in_buf), 32) & 0xffff); + return ERROR_OK; +} + +/* read JTAG buffer into u8, flipping bit-order */ +int arm_jtag_buf_to_8_flip(u8 *in_buf, void *priv) +{ + u8 *dest = priv; + *dest = flip_u32(le_to_h_u32(in_buf), 32) & 0xff; + return ERROR_OK; +} + +/* not-flipping variants */ +/* read JTAG buffer into host-endian u32 */ +int arm_jtag_buf_to_u32(u8 *in_buf, void *priv) +{ + u32 *dest = priv; + *dest = le_to_h_u32(in_buf); + return ERROR_OK; +} + +/* read JTAG buffer into little-endian u32 */ +int arm_jtag_buf_to_le32(u8 *in_buf, void *priv) +{ + h_u32_to_le(((u8*)priv), le_to_h_u32(in_buf)); + return ERROR_OK; +} + +/* read JTAG buffer into little-endian u16 */ +int arm_jtag_buf_to_le16(u8 *in_buf, void *priv) +{ + h_u16_to_le(((u8*)priv), le_to_h_u32(in_buf) & 0xffff); + return ERROR_OK; +} + +/* read JTAG buffer into big-endian u32 */ +int arm_jtag_buf_to_be32(u8 *in_buf, void *priv) +{ + h_u32_to_be(((u8*)priv), le_to_h_u32(in_buf)); + return ERROR_OK; +} + +/* read JTAG buffer into big-endian u16 */ +int arm_jtag_buf_to_be16(u8 *in_buf, void *priv) +{ + h_u16_to_be(((u8*)priv), le_to_h_u32(in_buf) & 0xffff); + return ERROR_OK; +} + +/* read JTAG buffer into u8 */ +int arm_jtag_buf_to_8(u8 *in_buf, void *priv) +{ + u8 *dest = priv; + *dest = le_to_h_u32(in_buf) & 0xff; return ERROR_OK; } -- cgit v1.2.3
