PX4 on STM32F4Discovery

We'll try to run the PX4 firmware on the STM32F4Discovery board.  Some documentation can be found here.   We'll try to run everything from Linux.

First, we build the PX4 bootloader for f4discovery.  There is a specific makefile target, make px4discovery_bl.  To flash the bootloader, we can use texane stlink, which we will build.  After installing it, we can run stlink-gui and download the bootloader through the mini USB port, detected as STMicroelectronics ST-LINK/V2.

Then we build the PX4 firmware with make px4-stm32f4discovery_default.  We connect to the micro USB port; it is detected as PX4 BL DISCOVERY and /dev/ttyACM0 port is created.  To flash, make px4-stm32f4discovery_default upload.

Connect a USB Serial adapter to PA3 (RX) and PA2 (TX), and run screen /dev/ttyUSB0 57600 to access NuttX terminal.  The boot message, 

sercon: Registering CDC/ACM serial driver

sercon: Successfully registered the CDC/ACM serial driver
