From: David Brownell Date: Thu, 8 Oct 2009 20:15:18 +0000 (-0700) Subject: initial builds of OSK5912 boards need srst_pulls_trst X-Git-Tag: v0.3.0-rc0~119 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=41c1af7c672cfae188308b7b2ec994f9095e621d;p=openocd initial builds of OSK5912 boards need srst_pulls_trst This is clearly noted in the hardware spec (section 5.2.3); it works around a chip erratum: "If the MPU_RESET signal is used, it may cause the EMIFS bus to lock." I seem to have a board with such an initial build. The chip is labeled XOMAP. Presumably, parts without that "X" prefix (eXperimental) resolve this.
