从图中可以很明显看出ov5648配置选项位于->DeviceDrivers选项下的->Multimediasupport(MEDIA_SUPPORT[=y])下的->I2CEncoders,decoders,sensorsandotherhelperchips的选项中, 其实也可以按下"1"直接可以定位到对应的选项, 然后选中以下内容即可,具体见图:
$ make boot ROOTDEV=ram0 // support by all boards, basic boot method $ make boot ROOTDEV=nfs // depends on network driver, only raspi3 not work $ make boot ROOTDEV=sda $ make boot ROOTDEV=mmcblk0 $ make boot ROOTDEV=vda // virtio based block device ...

The lsmod command prints currently loaded kernel modules like device drivers. This includes networking, storage, and other hardware-related modules being used by the Linux kernel to interface with internal and external devices.lsmodModule Size Used byipv6 406206 27evdev 17700 0crct10dif_pclmul ...
Processes can voluntarily yield the CPU by simply callingschedule(). This is most commonly used in kernel code and device drivers that want to sleep or wait for a signal to occur.7Other tasks want to continually use the CPU and the system timer must tell them to yield. The Linux kernel ...

$ make kernel JOBS=1 可运行如下命令调试: $ make debug 该命令将使用 tmux 分割出两个终端分别运行 QEMU 和 gdb,并从 .gdb/kernel.default 加载脚本。 可以使用 CTRL+b+方向键(例如←) 来切换 tmux 的窗格。 如果想修改调试脚本,可以拷贝一份到 .gdb/kernel.user,这样就可以无缝升级: $ cp .gdb/...
dev 是 Device(设备) 的缩写, 该目录下存放的是 Linux 的外部设备,在 Linux 中访问设备的方式和访问文件的方式是相同的。 /etc: etc 是 Etcetera(等等) 的缩写,这个目录用来存放所有的系统管理所需要的配置文件和子目录。 /home:(普通用户家目录)
