#鸿蒙通关秘籍#如何在鸿蒙LiteOS-M内核中实现LittleFS文件系统的初始化？

要在鸿蒙LiteOS-M内核中初始化LittleFS文件系统，可以利用lfs_config结构体配置相关参数，并实现底层读写擦除同步接口。 c struct lfs_config cfg = { .context = NULL, .read = user_read, // Implement your own read function .prog = user_prog, // Implement your own prog function .erase = user_erase, // Implement your own erase function .sync = user_sync, // Implement your own sync function .read_size = 16, .prog_size = 16, .block_size = 4096, .block_count = 1024, .block_cycles = 500, .cache_size = 16, .lookahead_size = 16, .read_buffer = malloc(16), .prog_buffer = malloc(16), .lookahead_buffer = malloc(16), .name_max = 32, .file_max = 128, .attr_max = 64, .metadata_max = 64 };

lfs_t lfs; // Format the file system int err = lfs_mount(&lfs, &cfg); if (err) { lfs_format(&lfs, &cfg); lfs_mount(&lfs, &cfg); }
