根据坛友所授方法：
+ J7 {9 g6 I8 }8 c; ^# F+ V: }" c
接ttl，打开串口，上电，不断点击回车，进uboot，依次输入以下命令：
# ^6 X) B: @1 ?; {/ K Z- P' C" ` I sf probe
" }5 [2 ~( D' N5 B0 ]/ [sf updatemacsn 112233445566 12345abcdefgh1 Z6 g" ^' V2 ^ e* w# @; i6 l
112233445566为mac，后者为sn，按需修改
9 \9 I- ]- v# c: Z j2 |$ c4 x, Z+ f8 M- n4 {/ |
没有修改成功# F, {' }6 D. A, Q
求指点 问题出在哪儿，不知道是不是命令输入有误9 }% j2 V- P7 y* q3 _
在此跪谢给位大佬
