/***************************************************************************** * I.MX6 U-boot imxotp MAC address 写入 * 说明: * I.MX6DL默认是没有MAC地址的,从代码来看,是由自动生成MAC地址的,但是在 * U-boot阶段是可以通过imxotp进行MAC地址的写入的。 * * 2016-6-24 深圳 南山平山村 曾剑锋 ****************************************************************************/ 一、参考文档: How to uBoot & Kernel – Compile, Flash, Update, Boot http://www.imx6rex.com/software/how-to-uboot-compile-flash-update/ 二、操作: 1. Program eFuses to set the MAC address. Be sure that you set the correct address – it cannot be changed back. 2. 示例: //!!BEAWARE: Once you blow a bit to 1, it can NOT be changed back to 0!! //USE YOUR MAC ADDRESS!!!!, this is just en example // example MAC Address: 00:0d:15:00:bc:4a > imxotp blow --force 23 0x000d > imxotp blow --force 22 0x1500bc4a
