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 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. * ****************************************************************************/ int board_app_initialize(uintptr_t arg) { #ifdef HAVE_RTC_DRIVER FAR struct rtc_lowerhalf_s *rtclower; #endif #ifdef CONFIG_SENSORS_QENCODER int index; char buf[9]; #endif int ret; (void)ret; #ifdef HAVE_PROC /* Mount the proc filesystem */ syslog(LOG_INFO, "Mounting procfs to /proc\n"); ret = mount(NULL, CONFIG_NSH_PROC_MOUNTPOINT, "procfs", 0, NULL); if (ret < 0) { syslog(LOG_ERR, "ERROR: Failed to mount the PROC filesystem: %d (%d)\n", ret, errno); return ret; } #endif #ifdef HAVE_RTC_DRIVER /* Instantiate the STM32L4 lower-half RTC driver */ rtclower = stm32l4_rtc_lowerhalf(); if (!rtclower) { serr("ERROR: Failed to instantiate the RTC lower-half driver\n"); return -ENOMEM; } else { /* Bind the lower half driver and register the combined RTC driver * as /dev/rtc0 */ ret = rtc_initialize(0, rtclower); if (ret < 0) { serr("ERROR: Failed to bind/register the RTC driver: %d\n", ret); return ret; } } #endif #ifdef HAVE_MMCSD /* First, get an instance of the SDIO interface */ g_sdio = sdio_initialize(CONFIG_NSH_MMCSDSLOTNO); if (!g_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 */ ret = mmcsd_slotinitialize(CONFIG_NSH_MMCSDMINOR, g_sdio); if (ret < 0) { syslog(LOG_ERR, "ERROR: Failed to bind SDIO to the MMC/SD driver: %d\n", ret); return ret; } /* Then let's guess and say that there is a card in the slot.
