From d644ad41f5a17315ab72f6ebeeecf895f7d41679 Mon Sep 17 00:00:00 2001 From: Peter Pickford Date: Tue, 22 Apr 2014 13:45:42 +0100 Subject: [PATCH] [serial] Enable UART FIFOs Escape sequences received via the serial console can fail since the cpu_nap() in getchar_timeout() can delay processing for more than the time it takes for a single character to arrive. Fix by enabling the UART FIFOs.
