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

请问您是在TI的demo板上测试的么?建议用TI的SDK

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?

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

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

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
