From d7eaa9faa839a1219d19a51f117fa9dc8fee42a4 Mon Sep 17 00:00:00 2001 From: Enrico Scholz Date: Mon, 7 Feb 2011 23:53:05 +0000 Subject: cortex-m3: adjusted target cflags Explicit '-mthumb' is required because Cortex-M3 does not support ARM instructions and actual flags cause gcc to fail with 'error: target CPU does not support ARM mode'. The '-mcpu=cortex-m3' is shorter than '-march=armv7-m -mtune=cortex-m3' and enables workarounds like '-mfix-cortex-m3-ldrd'.
