703n变砖，上TTL还是不行，求助。

辛巴德船长

703n换了8M FLASH,原来刷4M的trunk固件，后来刷8M的小标固件变砖。上电红灯长亮，捅屁屁没反应。上TTL如下：

对比了其他兄弟的TTL信息发现前面都一样，从这句All bugs added by David S. Miller <davem@redhat.com>下面开始出错，还有什么办法？求助！！

SF。通电后按“p“也不停。

用autottl 刷4m的固件，cpu选择7241  试试看。

哈，谢谢提醒！试了N次，刷了个4M的固件。救回来了，十分感谢！

你要按的是TPL不是P

楼主，你4M的闪存，刷8M的固件，肯定砖头啊

703N是个论坛里的朋友转让的，换了8M的FLASH，芯片是mx 25L6445E。不过不知道他为什么刷的是4M的TRUNK固件。
