N9H30 FMI NAND controller driver for RT-Thread已實作完成，初步測試ok。
因目前整體 FMI NAND controller + YAFFS + rt_mtd_nand HAL，我有打些patch，這些patch未來會更新在核心版本上，Rt-thread studio的核心版本選項只有4.1.0，所以不特別釋出sdk-bsp-nk-n9h30開發包。
(CI會因編譯不過，不能被合入。)

所以，我另開了一個Branch https://github.com/wosayttn/sdk-bsp-nk-n9h30/tree/fminand 
透過下載zip，在RT-Thread SDK Manager介面上，選擇安裝離線包的方式，也可使用到rt-thread studio進行開發編譯。

Step1: 下載zip檔案 Download ZIP

Step2: RT-Thread SDK Manager安裝離線包

Step3:  Create NK-N9H30 demo template project。

Step4:  更新rt_mtd_nand_device 結構，儲存file system context。

You need modify rt_mtd_nand_device structure as below for passing the source building using this v1.0.1.
```c
struct rt_mtd_nand_device
{
    struct rt_device parent;

rt_uint16_t page_size;          /* The Page size in the flash */
    rt_uint16_t oob_size;           /* Out of bank size */
    rt_uint16_t oob_free;           /* the free area in oob that flash driver not use */
    rt_uint16_t plane_num;          /* the number of plane in the NAND Flash */

rt_uint32_t pages_per_block;    /* The number of page a block */
    rt_uint16_t block_total;

/* Only be touched by driver */
    rt_uint32_t block_start;        /* The start of available block*/
    rt_uint32_t block_end;          /* The end of available block */

/* operations interface */
    const struct rt_mtd_nand_driver_ops *ops;

+    void* priv;
};
+ typedef struct rt_mtd_nand_device* rt_mtd_nand_t;
```
