[En-Nut-Discussion] NutOs5.1 on STM32 controllers

[Holger Mai, GEMAC]

Hello all
i want to run NutOS on an Olimex STM32-E407 with a ST32F407 controller. Thera are some
configurations near this for STM32 controllers, but with all of them it is impossible to compile
the NutOS with Arm GCC. Looks like an error in basic configuration for gcc.

One example for simple CM3 chip configuration usps_f107c.conf:

10:57:16: ----- Running 'make all' -----

The toolchain is Arm_None_Eabi_gcc  4.6 2012q4 under Windows7, and it works fine with
Eclipse and CooCox Projects for many STM32 Chips.
