我已经在buildroot中启用了BR2_LINUX_KERNEL [= y]。 Linux配置为使用初始RAM文件系统,因此构建内核需要rootfs映像(应由buildroot创建)。 当我在buildroot根目录下运行make时,构建失败并显示错误信息“Cannot open 'buildroot-2013.05/output/images/rootfs.cpio'”,因为(如果我理解正确),构建顺序是工具链 - 软件包 -...

changes">更改 MCU 配置以优化功耗 更改固件以优化功耗 结论 硬件 我们需要一个实时时钟 (RTC),一个用于屏幕的串行外设接口 (SPI),一个用于天气传感器的 I2C 接口,以及至少 16KB 的 RAM 和 64KB 的 ROM,所有这些都最好具有尽可能低的功耗。 我将使用基于 STM32L432 MCU 的 ...
to profile the kernel have the vmlinux binary ready If you want to profile a native application, compile it with debugsymbols (-g) After system has loaded, execute once: “opcontrol setup –event=CPU_CYCLES:50000″ If you also want to profile the kernel, add theparams “–vmlinux=...
system calls, which is one of the reasons we are using blocking thread IOs. We can maximize system throughput because at any given point some threads are reading while others are writing, and data is buffered on both paths - keeping each subsystem busy while minimizing kernel to userspace ...
监控系统启动后,嵌入式Linux系统启动Web Server服务程序,或者自己手动启动Web Server服务程序,接收授权客户端浏览器的请求,Web Server将根据通信协议完成相应的监测。客户端就可以时时看到服务器端监控的图像。客户端可以通过浏览器或者安装客户端软件进行监控,如果是通过浏览器需要安装JAVA插件。通过在开发板的摄像头监控...
