From 5295bb3121e535d25a4bdef0bd41a5675cb2f47d Mon Sep 17 00:00:00 2001 From: oharboe Date: Tue, 15 Apr 2008 19:08:25 +0000 Subject: - sw_bkpts fails if the target is not halted. The side effect is that sw_bkpts also fails if the target is an unknown state(i.e. not examined yet). - feroceon embedded ICE registers are now set up after TRST has been deasserted(not tested, but it was broken as is anyway). git-svn-id: svn://svn.berlios.de/openocd/trunk@582 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- src/target/arm7_9_common.c | 6 +++++ src/target/feroceon.c | 65 +++++++++++++++++++++++++++------------------- 2 files changed, 44 insertions(+), 27 deletions(-) (limited to 'src') diff --git a/src/target/arm7_9_common.c b/src/target/arm7_9_common.c index d3445257..191e91c5 100644 --- a/src/target/arm7_9_common.c +++ b/src/target/arm7_9_common.c @@ -2434,6 +2434,12 @@ int handle_arm7_9_sw_bkpts_command(struct command_context_s *cmd_ctx, char *cmd, armv4_5_common_t *armv4_5; arm7_9_common_t *arm7_9; + if (target->state != TARGET_HALTED) + { + LOG_ERROR("target not halted"); + return ERROR_TARGET_NOT_HALTED; + } + if (arm7_9_get_arch_pointers(target, &armv4_5, &arm7_9) != ERROR_OK) { command_print(cmd_ctx, "current target isn't an ARM7/ARM9 target"); diff --git a/src/target/feroceon.c b/src/target/feroceon.c index 0cd632bd..73c25be7 100644 --- a/src/target/feroceon.c +++ b/src/target/feroceon.c @@ -54,7 +54,7 @@ #include #include - +int feroceon_examine(struct command_context_s *cmd_ctx, struct target_s *target); int feroceon_target_command(struct command_context_s *cmd_ctx, char *cmd, char **args, int argc, struct target_s *target); int feroceon_bulk_write_memory(target_t *target, u32 address, u32 count, u8 *buffer); int feroceon_init_target(struct command_context_s *cmd_ctx, struct target_s *target); @@ -94,7 +94,7 @@ target_type_t feroceon_target = .register_commands = arm926ejs_register_commands, .target_command = feroceon_target_command, .init_target = feroceon_init_target, - .examine = arm9tdmi_examine, + .examine = feroceon_examine, .quit = feroceon_quit }; @@ -568,32 +568,7 @@ int feroceon_bulk_write_memory(target_t *target, u32 address, u32 count, u8 *buf int feroceon_init_target(struct command_context_s *cmd_ctx, struct target_s *target) { - armv4_5_common_t *armv4_5; - arm7_9_common_t *arm7_9; - arm9tdmi_init_target(cmd_ctx, target); - - armv4_5 = target->arch_info; - arm7_9 = armv4_5->arch_info; - - /* the COMMS_CTRL bits are all contiguous */ - if (buf_get_u32(arm7_9->eice_cache->reg_list[EICE_COMMS_CTRL].value, 2, 4) != 6) - LOG_ERROR("unexpected Feroceon EICE version signature"); - - arm7_9->eice_cache->reg_list[EICE_DBG_CTRL].size = 6; - arm7_9->eice_cache->reg_list[EICE_DBG_STAT].size = 5; - arm7_9->has_monitor_mode = 1; - - /* vector catch reg is not initialized on reset */ - embeddedice_set_reg(&arm7_9->eice_cache->reg_list[EICE_VEC_CATCH], 0); - - /* clear monitor mode, enable comparators */ - embeddedice_read_reg(&arm7_9->eice_cache->reg_list[EICE_DBG_CTRL]); - jtag_execute_queue(); - buf_set_u32(arm7_9->eice_cache->reg_list[EICE_DBG_CTRL].value, 4, 1, 0); - buf_set_u32(arm7_9->eice_cache->reg_list[EICE_DBG_CTRL].value, 5, 1, 0); - embeddedice_store_reg(&arm7_9->eice_cache->reg_list[EICE_DBG_CTRL]); - return ERROR_OK; } @@ -660,3 +635,39 @@ int feroceon_target_command(struct command_context_s *cmd_ctx, char *cmd, char * return ERROR_OK; } + + +int feroceon_examine(struct command_context_s *cmd_ctx, struct target_s *target) +{ + int retval; + + retval=feroceon_examine(cmd_ctx, target); + if (retval!=ERROR_OK) + return retval; + + armv4_5_common_t *armv4_5; + arm7_9_common_t *arm7_9; + + armv4_5 = target->arch_info; + arm7_9 = armv4_5->arch_info; + + /* the COMMS_CTRL bits are all contiguous */ + if (buf_get_u32(arm7_9->eice_cache->reg_list[EICE_COMMS_CTRL].value, 2, 4) != 6) + LOG_ERROR("unexpected Feroceon EICE version signature"); + + arm7_9->eice_cache->reg_list[EICE_DBG_CTRL].size = 6; + arm7_9->eice_cache->reg_list[EICE_DBG_STAT].size = 5; + arm7_9->has_monitor_mode = 1; + + /* vector catch reg is not initialized on reset */ + embeddedice_set_reg(&arm7_9->eice_cache->reg_list[EICE_VEC_CATCH], 0); + + /* clear monitor mode, enable comparators */ + embeddedice_read_reg(&arm7_9->eice_cache->reg_list[EICE_DBG_CTRL]); + jtag_execute_queue(); + buf_set_u32(arm7_9->eice_cache->reg_list[EICE_DBG_CTRL].value, 4, 1, 0); + buf_set_u32(arm7_9->eice_cache->reg_list[EICE_DBG_CTRL].value, 5, 1, 0); + embeddedice_store_reg(&arm7_9->eice_cache->reg_list[EICE_DBG_CTRL]); + + return ERROR_OK; +} -- cgit v1.2.3
