Nevertheless, one of the purposes of this short Linux kernel driver tutorial is to show how to work with logging into the kernel and how to interact with device files. These tools may be simple, but they come in
更新触摸固件的方法很简单,介绍如下。首先将“~/embed_linux_driver_tutorial_imx6_code/linux/touch_scream_GTxxx”下的固件拷贝到开发板的“/lib/firmware”目录下,然后重启开发板,按照 前面的步骤重新加载驱动即可。添加更新固件后再次加载驱动输入结果如下所示。

For simplicity, this brief tutorial will only cover type char devices loaded as modules. Kernel 2.6.x will be used (in particular, kernel 2.6.8 under Debian Sarge, which is now Debian Stable). User space and kernel space When you write device drivers, it’s important to make the ...
