根据坛友所授方法：! [5 S- b' u2 z, I; p) v
- u- [, @2 V3 ]2 ?2 }* |接ttl，打开串口，上电，不断点击回车，进uboot，依次输入以下命令：
8 v4 O& G5 Z7 K- r1 T sf probe# U: H! Y$ | M3 `" k7 S; C: `" B; x
sf updatemacsn 112233445566 12345abcdefgh
9 R K/ R% V7 B/ l1 D 112233445566为mac，后者为sn，按需修改
0 c4 @! t3 e# s% l% F. E( J4 n/ _, ?* Q; t
没有修改成功1 V, l% _9 U. T# d; k! N
求指点 问题出在哪儿，不知道是不是命令输入有误! H B8 h# N# |1 G1 f
在此跪谢给位大佬
