Knowledge Point Analysis: Yang Tian m4900c model (Intel H110 chipset, Skylake platform), the user said that in the case of no USB storage device, the system notification area see the security Removal hardware icon, how to solve? Operation Steps: The computer is currently a dual hard disk (SSD+HDD), the system is currently installed into SSDs, the notifica

The following exception may be the so library and system hardware architecture does not conform to 04-17 11:13:56.672 W/linker (3090): libxxx.so has text relocations.

involves three types of voltages. the kernel and I/O of s3c2440a are separately supplied. The operating I/O voltage is 3.3 V, and the operating voltage of the kernel is 1.25 v, the memory chip and reset chip that are directly connected to the processor also use 3.3 V power, and the peripheral circuit uses 5 V power. Based on different power supply voltages, the system uses two as1117 series low voltage differential DC regulator chips to convert 5 v d

The information is as follows: [[UIDevice currentDevice] systemName]: system name, for example, iPhone OS [[UIDevice currentDevice] systemVersion]: system version, for example, 4.2.1 [[UIDevice currentDevice] model]:

Circuit General purpose IO Interface (gpio) is a very important I/O interface in the arm system and on-chip SOC (System-on-chip) systems, it has the advantages of flexible use, good configurability, and low hardware cost, and is widely used in arm systems. Gpio is not only practical, but also powerful, mainly including the following six functions. L General I/O

Here are the main problems encountered two: the first is that the HAL layer of the source code to add to the Android default compilation, that is, in the root directory to do make, their own HAL source code will be compiled. The second problem is that after the compilation is complete, it is automatically installed under the specified system directory LIB/HW.At first, you don't know much, you always need to use MMM to compile and install, but it's unr
