From af79925eb1937044977f969a53ea3b7635f576b1 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Mon, 14 Dec 2009 15:55:51 -0800 Subject: jtag: add '-ignore-version' option Add a "-ignore-version" to "jtag newtap" which makes the IDCODE comparison logic optionally ignore version differences. Update the "scan_chain" command to illustrate this by showing the "*" character instead of the (ignored) version nibble.
