README
======
This README discusses issues unique to NuttX configurations for the
STMicro STM32L0538-DISO development board. The STM32L0538-DISO board
is based on the STM32L053C8 MCU (64Kbytes FLASH, 8Kbytes of SRAM and
6Kbytes of EEPROM).
The board features:
- An ST-LINK/V2-1 embedded debug tool interface,
- 2.13" E-paper display, 122×250 pixels
- USB 2.0 FS
- One linear touch sensor or four touchkeys
- IDD current measurement

* Name: board_app_initialize
*
* Description:
* Perform application specific initialization. This function is never
* called directly from application code, but only indirectly via the
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
*
* 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.
