新编译的内核版本,串口启动程序停在了这里,过一段时间自动重启 哪位大神给看看问题出在哪?

david liang1:

从https://github.com/beagleboard/kernel/tree/3.8-rt下载的内核版本,有人用过吗

Jian Zhou:

回复 david liang1:

请问您是在TI的demo板上测试的么?建议用TI的SDK

david liang1:

回复 Jian Zhou:

板子是beaglebone black,自带的内核版本是3.8.13的,SDK内核版本是3.8的吗?

david liang1:

回复 Jian Zhou:

请问目前我这种情况怎么处理,之前我用了从https://github.com/beagleboard/kernel/tree/下载的3.8版本的内核已经编译烧写成功了,这次换成3.8-rt的就出现这种情况,实在是没找到错误的原因

回复 david liang1:

兄弟  这个问题你解决了没有   我一模一样的问题    

Denny%20Yang99373:

回复 buhui zhao:

看看是不是DTS的文件需要同步修改?

Yaoming Qin:

回复 david liang1:

建议使用processor sdk http://www.ti.com/tool/PROCESSOR-SDK-AM335X?keyMatch=processor%20sdk&tisearch=Search-EN-Everything

leo chen:

回复 Yaoming Qin:

是否可以把bootargs里面的quiet 参数去掉

这样看看内核启动的时候log打印到什么问题

也便于进一步的确认问题
