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

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?
