Raspberry Pi 使用一个配置文件config.txt代替了传统计算机 BIOS 的功能,该文件会在启动阶段被树莓派上的引导固件读取(由 GPU 在 CPU 和 Linux 初始化之前执行),所以它被放置在了存储卡的第 1 个引导分区。 但是该文件同样可以在登入 Raspbian 系统之后,通过编辑/boot/config.txt文件执行修改操作,所有设置都会在 ...

所谓麻雀虽小五脏俱全, 用来形容树莓派( Raspberry Pi) 最好不过了 , 这块信用卡般大小的主板拥有和pc样的能力。USB, Ethernet, HDMI, RCA, 3. 5mm Stereo Jack, 还有无比强大的GPIO, 当然我很少能用到这个。 树莓派2采用了900MHz的四核ARM Cortex-A7处理器(性能是前代的6倍以上),1GB的LPDDR2 SDRAM(内存...
is capable of booting from a USB drive. To do this you'll first need toprogram USB boot mode(this is unnecessary on the 3B+ as USB booting is on by default). For the original Pi 2, or if you are having problems with USB booting, then you cancopy the bootcode.bin file to an SD...
我们在上篇《开源硬件平台全新简介 (1) Raspberry Pi “树莓派”(上): 概述与优势》中,介绍了Raspberry Pi的基本信息与竞争优势。当时留了个坑:“可以赞,就当然必须喷,没得喷不科学”。今天就填这个大坑。 (因为参加Maker Faire Shenzhen深圳制汇节造成的延期深感抱歉。欢迎您阅读我们对这场展会的所有原创报道!
