+README
+======
+
+The NuttX configuration for the Olimex STM32-P207 is assembled mainly
+from the configurations stm32f4discovery and stm3240g-eval.
+
+It was tested with the NuttX EABI "buildroot" Toolchain.
+
+Debugging with OpenOCD via an Olimex ARM-USB-TINY-H works. Note that
+CONFIG_DEBUG_SYMBOLS and CONFIG_STM32_DISABLE_IDLE_SLEEP_DURING_DEBUG
+are enabled so that the JTAG connection is not disconnected by the idle
+loop.
+
+The following peripherals are enabled in this configuration.
+ - LEDs:       show the sytem status
+ 
+ - Buttons:    TAMPER-button, WKUP-button, J1-Joystick (consists of RIGHT-,
+               UP-, LEFT-, DOWN-, and CENTER-button). Built in app
+               'buttons' works.
+               
+ - ADC:        ADC1 samples the red trim potentiometer AN_TR
+               Built in app 'adc' works.
+               
+ - USB-FS-OTG: enabled but not really tested, since there is only a
+               USB-A-connector (host) connected to the full speed µC inputs.
+               The other connector (device) is connected to the high speed µC
+               inputs, but it seems that NuttX has currently no driver
+               for it.
+ 
+ - CAN:        Built in app 'can' works, but appart from that not really tested.
+ 
+ - Ethernet:   Ping to other station on the network works.

+ *   button enumeration value that uniquely identifies a button resource. See the
+ *   BUTTON_* definitions in board.h for the meaning of enumeration
