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. * ****************************************************************************/ static struct spi_dev_s *spi3; __EXPORT int board_app_initialize(uintptr_t arg) { px4_platform_init(); #if defined(SERIAL_HAVE_RXDMA) /* set up the serial DMA polling at 1ms intervals for received bytes that have not triggered a DMA event. */ static struct hrt_call serial_dma_call; hrt_call_every(&serial_dma_call, 1000, 1000, (hrt_callout)stm32_serial_dma_poll, NULL); #endif /* configure the DMA allocator */ if (board_dma_alloc_init() < 0) { syslog(LOG_ERR, "DMA alloc FAILED\n"); } stm32_spiinitialize(); spi3 = stm32_spibus_initialize(CONFIG_NSH_MMCSDSPIPORTNO); if (!spi3) { syslog(LOG_ERR, "[boot] FAILED to initialize SPI port 3\n"); rgb_led(255, 0, 0, 0); return -ENODEV; } int ret = mmcsd_spislotinitialize(CONFIG_NSH_MMCSDMINOR, CONFIG_NSH_MMCSDSLOTNO, spi3); if (ret < 0) { syslog(LOG_ERR, "[boot] Failed to bind SPI port 0 to SD slot 0\n"); rgb_led(255, 0, 0, 0); return ret; } #if defined(FLASH_BASED_PARAMS) static sector_descriptor_t params_sector_map[] = { {2, 16 * 1024, 0x08008000}, {3, 16 * 1024, 0x0800C000}, {0, 0, 0}, }; /* Initialize the flashfs layer to use heap allocated memory */ int result = parameter_flashfs_init(params_sector_map, NULL, 0); if (result != OK) { syslog(LOG_ERR, "[boot] FAILED to init params in FLASH %d\n", result); rgb_led(255, 0, 0, 0); return -ENODEV; } #endif // FLASH_BASED_PARAMS rgb_led(0, 255, 0, 0); return OK; }
