歌华链 ttl 没反应 求助

wjz376

刷了歌华链的伪固件。。。telnet密码提示错误，进不去了，转而用ttl刷。。。没有反应。




线，用万用表测过是通的，线序gnd-gnd,tx-rx,rx-tx(对调过还是一样）


波特率57600


对插后，putty没有动做。。

TTL必须有bootloader运行才可以，不能TTL，bootloader损坏
如果可以telnet连接，只是密码错误，说明固件基本正常运作

所以看你帖子越看越迷糊

也许犯了低级错误，也许你给错了telnet后的地址，也许填错了com端口……

通过tftpd64,强刷降级成功1.21
可是一激动刷breed的时候少打了一行
本来应该cd/tmp && wget http://192.168.1.100/breed-mt7621-guhua-ghl-r-001.bin && mtd write -r breed-mt7621-guhua-ghl-r-001.bin Bootloader的。
只打了前半部分cd/tmp && wget http://192.168.1.100/breed-mt7621-guhua-ghl-r-001.bin Bootloader

现在变成这样了。。
还有救吗

我的歌华用ttl刷变砖了，最后拆下flash用编程器刷入breed才好

那你这说法，不会成砖的，还没刷机呢，只是下载固件到tmp文件夹，最后的mtd write -r breed-mt7621-guhua-ghl-r-001.bin Bootloader才是刷入到闪存的Bootloader

我也不知道哪来出问题，后面乱试居然给刷进去了
