downside is that no matter how big your card is, its partitioning depends on the operating system, which wastes some space. The command is as follows: DD if=raspybin bs=1kb count=4000 of=/dev/sdxx here xx is your SD card, don't make a mistake! Otherwise lose hard drive data at your own risk. I purchased a 8G SD card, after installing the raspybin image of Pi, insert the SD card slot, connect the mouse, keyboard and HDMI to power up. The firs
Preface
Because I have been very interested in linux, I started an experiment with Raspberry Pi and set up a simple php server to run typecho.
However, the process is extraordinary, and almost every step is stuck. in addition, compared with WordPress, typecho has less data, which makes the process of solving the problem a little difficult.
The first is the Raspberry
running at 1 Ghz and stable, but I am trying not to work here.
Now, you can modify your configuration and restart the device, but the modified configuration does not always work. For example, I cannot do it here. Then I find some suggestions in Stack Overflow and need to execute the following command:
Sudo syncSudo sh-c "echo 3>/proc/sys/vm/drop_caches"Sudo cp config.txt. saveSudo cp config.txt. save.1Sudo sync; exit
This will cause you to exit the t

The first thing to note is that the Raspberry Pi Debian system is automatically scanning the display, in most cases cannot be displayed in full screen, that is, the actual display of the desktop is larger than the display resulting in some windows can not be displayed or closed, Either the actual displayed effect is less than the size of the display, resulting in black border areas around it. If this is the

Generate executable code on another platform on one platform. Why do you have to cross-compile it? In a word: It is the last resort. Sometimes it is because the target platform is not allowed or unable to install the required compiler, but also need some characteristics of the compiler, sometimes because the target platform is resource-poor, unable to run the required compiler, and sometimes because the target platform has not been established, and even the operating system is not, not to run
