一步步玩pcDuino3--mmc下的bootloader

pcDuino3下支持mmc启动.官方的Uboot是採用SPL框架实现的,由于内部的SRAM空间达到32K,我们全然能够在这32K空间内编写一个完整可用小巧的bootloader来完毕引导Linux kernel的目的. 我们首先介绍下SPL框架,能够先看下<GNU ARM汇编--(十八)u-boot-採用nand_spl方式的启动方法>和<GNU ARM汇编--(十九)u-boot-nand-spl启动过程分析>.NAND_SPL也算是SPL框架下的一种模式. 当使用Nand f…

盛科(Centec)交换机 SmartConfig 特性
