[已解决】WR841 V7刷openwrt，配无线中继重启变砖

花***

悲剧，由于一个路由器不能覆盖怎么房间，于是想在做个中继，原固件不知如何中继。于是刷了openwrt，按着网上的方法开始配置中继，可是怎么都不成功。后来突发奇想是不是配置完后需要重启，于是我就重启了，然后悲剧就开始了。重启后有线口插网线亮灯，无线灯不亮，系统灯一直闪烁。我记得正常的时候，启动完成系统灯是常亮的。现在路由器无法访问，ping不通。重新上电也只会出现三次TTL=64然后就是一直不通。用TFTP软件上传固件也上传不上去。现在整了一根串口线，接在串口上面，能看到启动信息，不过启动信息里面夹杂着各种乱码。 进入Uboot好多命令输入后也是乱码。Uboot里面也不能上传固件。这到底是怎么回事啊？

这是PING的结果

下面两张是直接启动的TTL信息里面有很多乱码



下面这两张是启动到uboot后的信息

输入print能正常打印出env信息但是输入erase却显示乱码，就是最后一行的乱码。

求指点，我实在不知道该怎么整了

波特率看下
还有有没有去掉电容什么的

波特率看下
还有有没有去掉电容什么的

波特率设置的是115200，和env配置信息里面的相同。我还试了其他各种波特率小于115200的根本就接收不到启动信息，全是乱码，大于115200时打开串口出错。我用的是电脑自带的串口。按着网上的方法用两个三极管和几个电阻做了个简单的转换线。电容不知道你是指那里的电容，我没有拆过路由器上的原件。

好像记得要短接电容还是什么的

恩山搜索下
你看下我的贴那个840  就是恩山找的
不过用编程器简单多了呢

邪恶***

传闻要拆电容TTL才显示正常的...

是短接C296，TTL附近的一个小电容

TTL附近有个C496 还有一个C206  没有C296.不知道是不是短496？？

对！

对！

论坛果然高手云集，我短接了496，现在确实先死正常了。
请帮我看看启动信息里面有些什么错误，为什么现在就不能正常启动了呢？？

下面就是没做任何处理的全部启动信息。。
