求大神路过
BSP启动内核卡在这里是什么问题

根文件系统有问题,
1. mmc有没有驱动
2. 卡有没有问题
3. 卡的第二个分区有没有根文件系统
4. 貌似文件系统类型也没指定吧, 默认有可能使用ext2/3/4文件系统，这些文件系统你有没有编译到内核
5. /dev/mmcblk0p2 是不是刚好指向你上面那个文件系统？

晕哥 · 2018-04-20 14:54:05

基于上面那些问题，建议还是先烧一个能跑起来的系统吧，然后插卡，看卡是否正常。

小猪佩奇 · 2018-04-20 14:56:23

晕哥，是这样的
同样的卡，同样的文件系统，主线linux正常启动

小猪佩奇 · 2018-04-20 14:57:59

我只是把卡的第一分区拷入配置好的script.bin ,uImage ,boot.scr

晕哥 · 2018-04-20 14:59:38

内核已经不同了, 设备树不同了, 文件系统有没有整合进来.
这些问题都得看一看。

建议先用 ramdisk, 就是根文件系统与 kernel一起打包那种方式，
先把系统跑起来，
然后插卡，
看系统是否能挂载 mmcblk0p2 的文件系统。

小猪佩奇 · 2018-04-20 17:40:34

会不会跟内核的配置有关，如果会，那么可能是内核哪里配置出问题

完全有可能，所以上面的步骤就是让你排除这些问题。
