STATUS
======
05/17: The basic NSH configuration is functional and shows that there is
3-4KB of free heap space. However, attempts to extend this have
failed. I suspect that 8KB of SRAM is insufficient to do much
with the existing NSH configuration. Perhaps some fine tuning
can improve this situation but at this point, I think this board
is only useful for the initial STM32 F0 bring-up, perhaps for
embedded solutions that do not use NSH and for general
experimentation.
There is also support for the Nucleo boards with the STM32 F072
and F092 MCUs. Those ports do not suffer from these problems and
seem to work well in fairly complex configurations. Apparently 8KB
is SRAM is not usable but the parts with larger 16KB and 32KB SRAMs
are better matches.

/* Four different clock sources can be used to drive the system clock (SYSCLK):

* - HSI high-speed internal oscillator clock

* - HSE high-speed external oscillator clock
* Normally driven by an external crystal (X3). However, this crystal is not
* fitted on the STM32F0-Discovery board.
* - PLL clock
* - MSI multispeed internal oscillator clock
* The MSI clock signal is generated from an internal RC oscillator. Seven frequency
* ranges are available: 65.536 kHz, 131.072 kHz, 262.144 kHz, 524.288 kHz, 1.048 MHz,
* 2.097 MHz (default value) and 4.194 MHz.
*
* The devices have the following two secondary clock sources
* - LSI low-speed internal RC clock
* Drives the watchdog and RTC. Approximately 37KHz
* - LSE low-speed external oscillator clock
* Driven by 32.768KHz crystal (X2) on the OSC32_IN and OSC32_OUT pins.

/* PLL Configuration
*
* - PLL source is HSI -> 8MHz input (nominal)
* - PLL source predivider 2 -> 4MHz divided down PLL VCO clock output
* - PLL multipler is 12 -> 48MHz PLL VCO clock output (for USB)
*
* Resulting SYSCLK frequency is 8MHz x 12 / 2 = 48MHz
*
* USB:
* If the USB interface is used in the application, it requires a precise
* 48MHz clock which can be generated from either the (1) the internal
* main PLL with the HSE clock source using an HSE crystal oscillator. In
* this case, the PLL VCO clock (defined by STM32F0_CFGR_PLLMUL) must be
* programmed to output a 96 MHz frequency. This is required to provide a
* 48MHz clock to the (USBCLK = PLLVCO/2). Or (2) by using the internal
* 48MHz oscillator in automatic trimming mode. The synchronization for
* this oscillator can be taken from the USB data stream itself (SOF
* signalization) which allows crystal-less operation.
* SYSCLK
* The system clock is derived from the PLL VCO divided by the output
* division factor.
* Limitations:
* - 96 MHz as PLLVCO when the product is in range 1 (1.8V),
* - 48 MHz as PLLVCO when the product is in range 2 (1.5V),
* - 24 MHz when the product is in range 3 (1.2V).
* - Output division to avoid exceeding 32 MHz as SYSCLK.
* - The minimum input clock frequency for PLL is 2 MHz (when using HSE as
* PLL source).

* Name: board_app_initialize

* Description:
* Perform application specific initialization. This function is never

*
* Input Parameters:
* arg - The boardctl() argument is passed to the board_app_initialize()
* implementation without modification. The argument has no
* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initalization logic and the
* matching application logic. The value cold be such things as a
* mode enumeration value, a set of DIP switch switch settings, a
* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.

/* The STM32F0Discovery board has four LEDs. Two of these are controlled by logic on the board and
* are not available for software control:
*
* LD1 COM: LD2 default status is red. LD2 turns to green to indicate that communications are in
* progress between the PC and the ST-LINK/V2.
* LD2 PWR: Red LED indicates that the board is powered.
*
* And two LEDs can be controlled by software:
*
* User LD_U: Green LED is a user LED connected to the I/O PC6 of the STM32F072 MCU.
* User LD_D: Blue LED is a user LED connected to the I/O PB7 of the STM32F072 MCU.
* User LD_L: Green LED is a user LED connected to the I/O PC8 of the STM32F072 MCU.
* User LD_R: Blue LED is a user LED connected to the I/O PB9 of the STM32F072 MCU.
*
* The other side of the LED connects to ground so high value will illuminate the LED.
