From f701c0cbeb346df4cda378d3b4d5136aabba3b37 Mon Sep 17 00:00:00 2001 From: Angus Gratton Date: Thu, 24 Jul 2014 08:14:04 +1000 Subject: [PATCH] newdap: Ignore -irlen/-irmask/etc newdap params on SWD or CMSIS-DAP Previously the -irlen parameter was required even though it is not a part of the SWD or CMSIS-DAP transports. This may eventually need to be changed for CMSIS-DAP once that supports JTAG as well.
