README
======
This README discusses issues unique to NuttX configurations for the
STMicro STM32G071B-DISCO development board. The STM32G071B-DISCO board
is based on the STM32G071RB MCU (128Kbytes FLASH and 32Kbytes of SRAM).
The boards features:
- An ST-LINK/V2-1 embedded debug tool interface,
- 128 x 64 pixels OLED display (SSD1315Z)
- LEDs,
- 4-way joystick
- USB Type-C current sensing based on the INA230 I2C
current-shunt and power monitor

* 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 initialization logic and the
* matching application logic. The value could 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.
