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) { int ret; #ifdef CONFIG_FS_PROCFS /* mount the proc filesystem */ syslog(LOG_INFO, "Mounting procfs to /proc\n"); ret = mount(NULL, "/proc", "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 NSH_HAVEMMCSD FAR struct spi_dev_s *ssp; /* Get the SSP port */ ssp = lpc17_sspbus_initialize(CONFIG_NSH_MMCSDSPIPORTNO); if (!ssp) { syslog(LOG_ERR, "ERROR: Failed to initialize SSP port %d\n", CONFIG_NSH_MMCSDSPIPORTNO); return -ENODEV; } syslog(LOG_INFO, "Successfully initialized SSP port %d\n", CONFIG_NSH_MMCSDSPIPORTNO); /* Bind the SSP port to the slot */ ret = mmcsd_spislotinitialize(CONFIG_NSH_MMCSDMINOR, CONFIG_NSH_MMCSDSLOTNO, ssp); if (ret < 0) { syslog(LOG_ERR, "ERROR: Failed to bind SSP port %d to MMC/SD slot %d: %d\n", CONFIG_NSH_MMCSDSPIPORTNO, CONFIG_NSH_MMCSDSLOTNO, ret); return ret; } syslog(LOG_INFO, "Successfuly bound SSP port %d to MMC/SD slot %d\n", CONFIG_NSH_MMCSDSPIPORTNO, CONFIG_NSH_MMCSDSLOTNO); #endif #ifdef CONFIG_PWM /* Initialize PWM and register the PWM device. */ ret = lpc17_pwm_setup(); if (ret < 0) { syslog(LOG_ERR, "ERROR: lpc17_pwm_setup() failed: %d\n", ret); return ret; } #endif UNUSED(ret); return OK; }
