The argument has no * meaning to NuttX; the meaning of the argument is a contract * between the board-specific initalization logic and the 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. * ****************************************************************************/ int board_app_initialize(uintptr_t arg) { #ifdef CONFIG_STM32_SPI1 FAR struct spi_dev_s *spi; FAR struct mtd_dev_s *mtd; #endif #ifdef NSH_HAVEMMCSD FAR struct sdio_dev_s *sdio; #endif int ret; /* Register I2C drivers on behalf of the I2C tool */ stm32_i2ctool(); /* Configure SPI-based devices */ #ifdef CONFIG_STM32_SPI1 /* Get the SPI port */ syslog(LOG_INFO, "Initializing SPI port 1\n"); spi = stm32_spibus_initialize(1); if (!spi) { syslog(LOG_ERR, "ERROR: Failed to initialize SPI port 0\n"); return -ENODEV; } syslog(LOG_INFO, "Successfully initialized SPI port 0\n"); /* Now bind the SPI interface to the M25P64/128 SPI FLASH driver */ syslog(LOG_INFO, "Bind SPI to the SPI flash driver\n"); mtd = m25p_initialize(spi); if (!mtd) { syslog(LOG_ERR, "ERROR: Failed to bind SPI port 0 to the SPI FLASH driver\n"); return -ENODEV; } syslog(LOG_INFO, "Successfully bound SPI port 0 to the SPI FLASH driver\n"); #warning "Now what are we going to do with this SPI FLASH driver?" #endif /* Create the SPI FLASH MTD instance */ /* The M25Pxx is not a give media to implement a file system.. * its block sizes are too large */ /* Mount the SDIO-based MMC/SD block driver */ #ifdef NSH_HAVEMMCSD /* First, get an instance of the SDIO interface */ syslog(LOG_INFO, "Initializing SDIO slot %d\n", CONFIG_NSH_MMCSDSLOTNO); sdio = sdio_initialize(CONFIG_NSH_MMCSDSLOTNO); if (!sdio) { syslog(LOG_ERR, "ERROR: Failed to initialize SDIO slot %d\n", CONFIG_NSH_MMCSDSLOTNO); return -ENODEV; } /* Now bind the SDIO interface to the MMC/SD driver */ syslog(LOG_INFO, "Bind SDIO to the MMC/SD driver, minor=%d\n", CONFIG_NSH_MMCSDMINOR); ret = mmcsd_slotinitialize(CONFIG_NSH_MMCSDMINOR, sdio); if (ret != OK) { syslog(LOG_ERR, "ERROR: Failed to bind SDIO to the MMC/SD driver: %d\n", ret); return ret; } syslog(LOG_INFO, "Successfully bound SDIO to the MMC/SD driver\n"); /* Then let's guess and say that there is a card in the slot.
