rax3000m刷openwrt固件

rax3000m刷机过程（nand版本）

刷机准备文件https://www.123pan.com/s/X5m9-6Ynj.html提取码:VtBW

接线关系：路由器lan口接电脑

1.上传配置开启ssh的配置文件（登录路由器后台管理界面在找到配置管理，上传配置文件rax3000m-1027开启ssh.conf）

2.刷写uboot

1.查看分区，为备份分区做铺垫，便于备份命名
root@RAX3000M:/tmp# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 08000000 00020000 "spi0.0"
mtd1: 00100000 00020000 "BL2"
mtd2: 00080000 00020000 "u-boot-env"
mtd3: 00200000 00020000 "Factory"
mtd4: 00200000 00020000 "FIP"
mtd5: 03d00000 00020000 "ubi"
mtd6: 02500000 00020000 "plugins"
mtd7: 00800000 00020000 "fwk"
mtd8: 00800000 00020000 "fwk2"2.备份分区
dd if=/dev/mtd0 |gzip > /tmp/mtd0_spi0.0.bin.gz
dd if=/dev/mtd1 of=/tmp/mtd1_BL2.bin
dd if=/dev/mtd2 of=/tmp/mtd2_u-boot-env.bin
dd if=/dev/mtd3 of=/tmp/mtd3_Factory.bin
dd if=/dev/mtd4 of=/tmp/mtd4_mtd4_FIP.bin
dd if=/dev/mtd5 of=/tmp/mtd5_ubi.bin
dd if=/dev/mtd6 of=/tmp/mtd6_plugins.bin
dd if=/dev/mtd7 of=/tmp/mtd7_fwk.bin
dd if=/dev/mtd8 of=/tmp/mtd8_fwk注意：第一步和第二步是选做，防止个别分区在刷固件的时候出错还原的，如果自己不会还原，就不备份了。3.上传文件并刷写uboot并校对
