用6410的核心板，自己做的底板，开机跑到一半核心板TXD就不输出信息了

我是用V3的核心板，然后自己画的底板，结果开机以后串口输出的信息是对的，一直跑到UBI:data offset 8192这个地方，接着核心板的TXD就再也没输出信号了，就挂住了。电源部分没问题，拨码也没问题，不知道还有没有什么其它的要注意的

有没有什么东西是标着要焊但实际上不用的呀

电路图跟天嵌的是一样的

你的底板上是不是去掉了网卡之类的东西？

是的，就只有串口，液晶还有音频

重新编译内核，去掉不用的外设驱动。然后烧写编译出来的镜像。

为什么这会有关系，难道检测不到不会跳过？而且最后卡住那地方不是在启动文件系统吗？

还是一样呀，你确定是这问题？

要不你说下底板需要的最小电路吧

你在内核中去掉了哪些东西呢？
