Raspberry Pi终于到手后，当然是把ARM Linux影像放到SD Card，再进行一系列的设置步骤，一开始使用Raspberry Pi时难免会遇到一些难题，本文会讨论数个有关Raspberry Pi的常见问题。<p style="line-height: 24px; text-align: left; border: 0px none rgb(68, 68, 68); color: rgb(68, 68, 68);

word-wrap: break-word;">在现阶段，由于市面上的周边硬件品牌众多，Raspberry Pi并不能完全兼容所有硬件的驱动程式，例如SD卡，建议使用级别4的SD卡(传输速率最低为4MB/秒)。而在安装ARM Linux影像到SD卡时，由于Rasipberry Pi发放的Linux影像大小都是2GB，如果你使用大于2GB的SD卡，会造成余下空间的浪费，所以这个清况下我们要把Linux影像扩展，以下的步骤会解释如何善用SD卡的余下空间，这个过程需要把swap分割区移至SD卡的最尾部份，然后把Linux系统分割区增大。</p><p style="line-height: 24px;
