“难道新版本的Db120-B1改了FLASH芯片 "MX29LV320T",这个用128K格式估计启动不了的吧.”
29LV128DBT2C-90Q，三星的颗粒。

貌似难度越来越大了

恩，新版本的大亚确实和之前有些不同。明天找两个拆开对比下

请问LS的大哥，我这个是否无可挽回了？

在论坛内ryanneo兄弟的指点下
作了一些仔细的检查
更新一下最新状况
首先，开机信息如下：

现在根据提示输入相应的设置参数后
SecreCRT信息会不停滚屏
在开始滚屏的第一屏
会显示如下内容：

然后报错，并不停滚屏，并且用Ctrl+C根本无法中止：

**Exception 32: EPC=8041CDEC, Cause=80407494 (AddrErrWr)
                RA=EFBFD465, VAddr=80522151

请留意上面的信息中有以下字段，看上去很奇怪的样子

我的也出现这种情况，关注中～～

秋日晨雾

我的也出现类似的情况,哪位想个什么办法弄下看!

ken9999

进CFE，刷个bin应该可以解决那个寄存器越界的翻屏问题，但仍然还是自动重启，十几秒间隔。看了下网上的flash文件，都是2.0版的，是否与2.1的不兼容？

ken9999

我是进入英文界面进行了一些操作之后出现这个现象的，刚开始还能概率连上192.168.1.1，后来就不行了，刷了一个bin后就挂了，用TTL线出现楼主的现象，在启动是狂按ctrl-C，再次进行刷机，终于可以正常显示启动过程，但依然自动重启，下面是一次启动的信息：
