From 28b0019803d33c25daebffe647c293093704f665 Mon Sep 17 00:00:00 2001 From: Paul Fertser Date: Thu, 14 Aug 2014 19:57:47 +0400 Subject: [PATCH] tcl/interface/ftdi: fix TRST for Olimex TINY adapters MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit According to the research by Eldar, TINY-H adapter has nTRST connected to ACBUS0 directly via a 100 Ohms series resistor. I think it's safe to assume the older TINY adapter does the same. See high-res photos at [1]. This patch should fix issues with JTAG for the case when nTRST is actually connected but is missing from the config.
