From 52d82e40b0332119d14f206555863c77b4f5edb3 Mon Sep 17 00:00:00 2001 From: Bob Feretich Date: Thu, 24 Feb 2011 13:16:44 +0000 Subject: [PATCH] OMAP3 Beagle Pin Mux initialization glitch fix The below patch reverses the order of two segments in the board file. Output pins need to have their values initialized, before they are exposed to the logic outside the chip.
