From 9b045f62f4bac2411a7662d8b312637347aac73d Mon Sep 17 00:00:00 2001 From: Spencer Oliver Date: Fri, 7 Dec 2012 11:08:33 +0000 Subject: [PATCH] flash: stm32lx fallback to slow memory writes when no working area The current stm32lx driver will fail if no working area is provided - fallback to using slow writes if this is the case.
