K3 A2 硬改换完NAND后TTL始终是100，我的电路板有点被我弄坏了。高手帮我看看NAND哪里应该断开哪里应该连接的？

绑定ip 192.168.2.2 后始终进的时miniweb ping 192.168.2.1 始终ttl=100，哎！搞了好久了不知道为啥。都已经切换到nand启动了！

从ttl看已经是在nand启动了啊，用tftp刷写固件进去即可

tem*** · 发表于 2018-6-27 15:21

刷了，没有用。启动还是进miniweb

看我的主板够惨的。哎！难道哪个nand短路后就会这样么？

楼主技术高超啊，没事情干，没坏理论都不要换nand吧

tem*** · 发表于 2018-6-28 10:48

如果我不设定192.168.2.1的话就获取不到ip，这是为啥啊。
nand的右边的电路都被我刮开了，难道焊接短路造成了这样？

nanni*** · 发表于 2018-6-28 10:56

你这焊盘再拆就应该废了，用放大镜看看有没有连脚，如果你用焊宝的话一定要清理干净，焊宝轻微导电的，最好的清理办法是用热风枪或者吹风机吹下脚，然后用洗板水清洗（四周贴片电阻要保护好）

jb*** · 发表于 2018-6-28 13:07

建议拆了nand看下焊盘，清理下

slk*** · 发表于 2018-7-4 21:09

140位置的电阻哪里去了？这个位置应该有一个电阻，以提高选择端电压到3.3v，已选择NAND启动的
