控制器作为 host

注意:

1.以下配置皆工作在 OTG 模式下，若不使用 OTG，则需要单独配置 host

2.硬件上 USB_ID 引脚需拉低

3.硬件上 USB_5V 引脚输出电压应大于 4.75V

1 IConfigTool配置​

以x2000_darwin_factory_defconfig为例. 打开IConfigTool工具,选择配置文件

2

选上自动挂载U盘到/tmp/mass_storage目录下

2 menuconfig 配置流程​

bhu@bhu-PC:~/work/build$ grep -nr "kernel" configs/x2000_darwin_factory_defconfig      //先查看kernel的配置
6:APP_kernel_dir=../kernel/kernel-x2000
7:APP_kernel_config=x2000_module_base_linux_sfc_nand_defconfig                         //kernel配置文件
bhu@bhu-PC:~/work/build$ cd ../kernel/kernel-x2000
bhu@bhu-PC:~/work/kernel/kernel-x2000$ make menuconfig

  Depends on: USB_SUPPORT [=y] && USB [=y] && SCSI [=y]


保存kernel配置

bhu@bhu-PC:~/work/kernel/kernel-x2000$ cp .config arch/mips/configs/x2000_module_base_linux_sfc_nand_defconfig

3 编译烧录​

重新编译配置

bhu@bhu-PC:~/work/build$ make x2000_darwin_factory_defconfig 

bhu@bhu-PC:~/work/build$ make

烧录固件, 没烧录过见烧录说明

4 使用方法​

插入 U 盘弹出打印信息

挂载 U 盘到文件系统

mount -t vfat /dev/sda1 mnt/

数据交换进入到 /mnt 目录即可操作
