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 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_NSH_HAVEMMCSD FAR struct spi_dev_s *spi; #endif int ret; #ifdef CONFIG_NSH_HAVEMMCSD /* Get the SPI port */ spi = lpc17_spibus_initialize(CONFIG_NSH_MMCSDSPIPORTNO); if (!spi) { message("board_app_initialize: Failed to initialize SPI port %d\n", CONFIG_NSH_MMCSDSPIPORTNO); return -ENODEV; } message("Successfully initialized SPI port %d\n", CONFIG_NSH_MMCSDSPIPORTNO); /* Bind the SPI port to the slot */ ret = mmcsd_spislotinitialize(CONFIG_NSH_MMCSDMINOR, CONFIG_NSH_MMCSDSLOTNO, spi); if (ret < 0) { message("board_app_initialize: Failed to bind SPI port %d to MMC/SD slot %d: %d\n", CONFIG_NSH_MMCSDSPIPORTNO, CONFIG_NSH_MMCSDSLOTNO, ret); return ret; } message("Successfully bound SPI port %d to MMC/SD slot %d\n", CONFIG_NSH_MMCSDSPIPORTNO, CONFIG_NSH_MMCSDSLOTNO); #endif #ifdef CONFIG_ADC /* Initialize ADC and register the ADC driver. */ ret = zkit_adc_setup(); if (ret < 0) { syslog(LOG_ERR, "ERROR: zkit_adc_setup failed: %d\n", ret); } #endif #ifdef CONFIG_CAN /* Initialize CAN and register the CAN driver. */ ret = zkit_can_setup(); if (ret < 0) { syslog(LOG_ERR, "ERROR: zkit_can_setup failed: %d\n", ret); } #endif UNUSED(ret); return OK; }
