From 69f78b0e413539ce358b011e1c1d820303e4f47a Mon Sep 17 00:00:00 2001 From: Geoffrey Noer Date: Mon, 11 Aug 1997 02:04:16 +0000 Subject: [PATCH] Sun Aug 10 16:49:09 1997 Geoffrey Noer * ocd.c: move ocd_write_bytes proto to ocd.h since it is used by ppc-bdm.c, use OCD_LOG_FILE to help debugging, define BDM_BREAKPOINT if not defined in tm.h (ocd_error): add new error cases (ocd_start_remote): send the OCD_INIT command before OCD_AYT and OCD_GET_VERSION calls, 80 was correct speed after all (ocd_write_bytes): no longer static (ocd_insert_breakpoint): no longer static (ocd_remove_breakpoint): new * ocd.h: add protos for ocd_write_bytes, ocd_insert_breakpoint, and ocd_remove_breakpoint * ppc-bdm.c: change bdm_ppc_ops so we call ocd_insert_breakpoint and ocd_remove_breakpoint instead of memory_insert_breakpoint and memory_remove_breakpoint. (bdm_ppc_open): after calling ocd_open, modify DER register so interrupts will drop us into debugging mode, finally disable the watchdog timer on the board so we don't leave BDM mode unexpectedly. --- gdb/ChangeLog | 2 +- gdb/ocd.c | 4 ++-- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 2adee78..f3f1edd 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -9,7 +9,7 @@ Sun Aug 10 16:49:09 1997 Geoffrey Noer BDM_BREAKPOINT if not defined in tm.h (ocd_error): add new error cases (ocd_start_remote): send the OCD_INIT command before - OCD_AYT and OCD_GET_VERSION calls + OCD_AYT and OCD_GET_VERSION calls, 80 was correct speed after all (ocd_write_bytes): no longer static (ocd_insert_breakpoint): no longer static (ocd_remove_breakpoint): new diff --git a/gdb/ocd.c b/gdb/ocd.c index ad575bc..b0463b2 100644 --- a/gdb/ocd.c +++ b/gdb/ocd.c @@ -158,7 +158,7 @@ ocd_start_remote (dummy) SERIAL_SEND_BREAK (ocd_desc); /* Wake up the wiggler */ - speed = 0; /* 80; /* Divide clock by 4000 */ + speed = 80; /* Divide clock by 4000 */ buf[0] = OCD_INIT; buf[1] = speed >> 8; @@ -1283,7 +1283,7 @@ ocd_load (args, from_tty) not yet supported fully */ #ifndef BDM_BREAKPOINT -#define BDM_BREAKPOINT 0x4a, 0xfa /* BGND insn on CPU32*/ +#define BDM_BREAKPOINT {0x0,0x0,0x0,0x0} /* For ppc 8xx */ #endif /* BDM (at least on CPU32) uses a different breakpoint */ -- 2.7.4
