From 5f9b74d0557ec577b45d7af18312bab58098c9d9 Mon Sep 17 00:00:00 2001 From: zwelch Date: Tue, 16 Jun 2009 00:23:00 +0000 Subject: David Brownell : Doc update: say "jtag newtap ... -disable" records the state after exiting the RESET state, matching the only implementation we're working with so far (TI ICEpick-C). Matching code updates. Now we can be sure that the "enabled" flag value is correct after JTAG resets. git-svn-id: svn://svn.berlios.de/openocd/trunk@2246 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- doc/openocd.texi | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'doc') diff --git a/doc/openocd.texi b/doc/openocd.texi index 304fc62a..7f73a4c3 100644 --- a/doc/openocd.texi +++ b/doc/openocd.texi @@ -2314,8 +2314,9 @@ A TAP may also provide optional @var{configparams}: @itemize @bullet @item @code{-disable} (or @code{-enable}) -@*Use the @code{-disable} paramater to flag a TAP which is not -linked in to the scan chain when it is declared. +@*Use the @code{-disable} parameter to flag a TAP which is not +linked in to the scan chain after a reset using either TRST +or the JTAG state machine's @sc{reset} state.
