Okay, I'll admit it. This is the first example of learning from a book.I started the raspberry Red version, version 2, see such a small card computer can do so many things, it is really surprising!installation system, etc. are very smooth, start, installation program, Remote Desktop, SSH login, etc. are very smooth, is installed XBMC not, various versions are not, start up after the operation will hang off, do not know what is the reason, power supply

Well, I admit that this is the first example of learning from books. I started with the Raspberry red edition and version 2. I was pleasantly surprised to see that such a small card computer could do so many things! The installation of the system is successful, and the startup, installation program, remote desktop, and SSH logon are all smooth, that is, the installation of XBMC is not good, and all versions are not good, after it is started up, the
