SPI NOR 驱动配置

Baremetal 配置

在 Luban-Lite 根目录下执行 scons --menuconfig，进入 menuconfig 的功能配置界面，按如下选择：

Board options  --->
    [*] Using Qspi0
    [ ] Using Qspi1
    [ ] Using Qspi2
    [ ] Using Qspi3
        Qspi0 Parameter  --->
             (100000000) Max frequency(Hz)
    [*] QSPI0 Devices: SPINOR  --->
        (100000000) SPINOR bus frequency(Hz)

Drivers options  --->
    AIC Bare Driver  --->
        [*] Enable AIC MTD Bare Driver
    Peripheral  --->
        -*- SPINOR Driver SFUD: Serial Flash Universal Driver

注：

为了方便配置, 使能 AIC_QSPI0_DEVICE_SPINOR 后, 会自动选上 AIC_SPINOR_DRV, LPKG_USING_SFUD, AIC_MTD_BARE_DRV

RTOS 配置

            -*- Using MTD Nor Flash device drivers
            -*- Using SPI Bus/Device device drivers
            -*-   Enable QSPI mode
            -*-   Using SFUD(Serial Flash Universal Driver)
            [*]     Using auto probe flash JEDEC SFDP parameter
            [*]     Using defined supported flash chip information table
            [*]     Using QSPI mode support
            (50000000) Default spi maximum speed(HZ)

注：

为了方便配置, 使能 AIC_QSPI0_DEVICE_SPINOR 后, 会自动选上 AIC_SPINOR_DRV, RT_USING_SFUD, LPKG_USING_SFUD, RT_USING_MTD_NOR

文件系统配置

Baremetal FatFS 配置

Local packages options  --->
    Third-party packages options  --->
        [*] DFS: device virtual file system for baremetal mode  --->
            [*]   Using posix-like functions, open/read/write/close
            (8)   The maximal number of mounted file system
            (4)   The maximal number of file system type
            (16)  The maximal number of opened files
            [ ]   Using mount table for file system
            [*]   Enable elm-chan fatfs
                    elm-chan's FatFs, Generic FAT Filesystem Module  --->
            [*]   Enable ReadOnly file system on flash
            [ ]   Enable RAM file system

RT-Thread FatFS 配置

Rt-Thread options  --->
    RT-Thread Components  --->
        [*] DFS: device virtual file system  --->
            [*]   Using posix-like functions, open/read/write/close
            [*]   Using working directory
            (4)   The maximal number of mounted file system
            (4)   The maximal number of file system type
            (16)  The maximal number of opened files
            [*]   Using mount table for file system
            [*]   Enable elm-chan fatfs
                    elm-chan's FatFs, Generic FAT Filesystem Module  --->
                        (4096) Maximum sector size to be handled.
            [ ]   Using devfs for device objects
            [*]   Enable ReadOnly file system on flash
            [ ]   Enable RAM file system

注意，上面的 Usingmounttableforfilesystem 选项打开后，意味着可以系统启动后会根据一个 Table 配置来自动挂载文件系统。该 Table 定义在 board.c 中：

#ifdef RT_USING_DFS_MNTTABLE
#include <dfs_fs.h>

const struct dfs_mount_tbl mount_table[] = {
#if (defined(AIC_USING_FS_IMAGE_TYPE_FATFS_FOR_0) || defined(AIC_USING_FS_IMAGE_TYPE_FATFS_FOR_1))
    {"blk_rodata", "/rodata", "elm", 0, 0, 0},
#endif
    {0}
};
#endif

FatFS 支持写功能

Baremetal，RT-Thread FatFS 都支持写功能，通过 makem 进行如下配置

make m

Application options  --->
     [*] FATFS enable write func in spinor

注：

因为 SPINOR 块大小是 4K，sector 是 512，代码兼容后，写速度较慢，不推荐使用 FatFS 写功能

RT-Thread Littlefs 配置

Local packages options  --->
    Third-party packages options  --->
        [*] Littlefs: A high-integrity embedded file system  --->
            (256) disk read size
            (256) disk write size
            (4096) disk block size
            (256) lfs r/w cache size
            (128) lfs lookahead size

注意，上面的 Usingmounttableforfilesystem 选项打开后，意味着可以系统启动后会根据一个 Table 配置来自动挂载文件系统。该 Table 定义在 board.c 中：

#ifdef RT_USING_DFS_MNTTABLE
#include <dfs_fs.h>

const struct dfs_mount_tbl mount_table[] = {
#ifdef LPKG_USING_LITTLEFS
    {"data", "/data", "lfs", 0, 0, 0},
#endif
    {0}
};
#endif
