UNT400B被我搞死了

neualan

哈哈哈,建议大家玩这个还是要用TTL能够正常通信的.
目前手上这个UNT400B用了快半个月,就是用的免TTL刷入,前天想折腾一下内核,重启就搞崩了,本来准备用TTL+hitool烧写恢复,串口终端接上乱码,结果一搜发现这个板子的TTL有个ttl转 232 的电路.
于是按照https://www.znds.com/forum.php?mod=viewthread&ordertype=1&tid=1173140的链接重新焊线,接上串口后终端可以跑码
又发现https://bbs.histb.com/d/199-ttlubuntu-nas帖子里说的这破板子能跑码（已正确接入tx）,但不能在跑码中输入指令
目前就是这个板子变砖了,发个帖跟各位老哥提个醒,顺便问问还有什么办法

neualan 我的短接usb刷成功出现界面，路由器有分配地址，但无法通过浏览器访问，能指点下么？

这是终端卡住的地方的最后几行,每次启动都卡这

看着是 rootfs （操作系统）加载不了，重做一下 kernel 或者 rootfs 吧
不折腾的话就直接刷配套的 kernel 和 rootfs

主要目前困在了无法TTL上,这个板子的TTL能够加电能够在终端跑码,烧写的时候却没法用,所以才是给大家提个醒,要折腾能够正常TTL的板子.

neualan 竟然TLL不能正常使用

JOJOJO

neualan 我的是连跑马都是乱码，看着他们都操作来直接开刷第一个fastboot就无法输入

JOJOJO

neualan 找到接线方式了，我不小心把一个电阻烧下来了，我发的求助帖里面有链接

ibobo

我就是用的这块板子，搞了一个晚上最终被无法TTL给搞死了

dearjoe

免TTL刷机，我试了，只有debian才能正常使用。其他的都不正常。
