From 23e22b6ec42c137b48ef6359075a0fe819706f3c Mon Sep 17 00:00:00 2001 From: dbrownell Date: Wed, 23 Sep 2009 22:03:41 +0000 Subject: Start handling the (second) SRST stage of reset better: make sure that when there are two or more targets, their various pre/post event reports are correctly ordered. Previously, only the first target always saw its "pre" method before SRST was asserted or deasserted. git-svn-id: svn://svn.berlios.de/openocd/trunk@2753 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- src/helper/startup.tcl | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-) (limited to 'src/helper/startup.tcl') diff --git a/src/helper/startup.tcl b/src/helper/startup.tcl index dc7b0450..7225929f 100644 --- a/src/helper/startup.tcl +++ b/src/helper/startup.tcl @@ -202,27 +202,32 @@ proc ocd_process_reset_inner { MODE } { } # Assert SRST, and report the pre/post events. - # - # REVISIT this presumes a single-target config, since SRST - # applies to the whole device-under-test.
