用androi的内核启动ubuntu文件系统

如题，谁有尝试过用android目录树中的kernel 代码编译出来的 zImage打包成的linux-boot.img 去启动ubuntu文件系统  有成功的吗

这个很多人都做成功了的，官方很多固件都是这样制作的。

那再请教下，android&ubuntu双系统的 android代码github地址能提供下吗，我这边试过android的内核都不行，引导不起来ubuntu文件系统一直进入initramfs 终端，找不到linuxroot。

代码都在 ：https://github.com/T-Firefly
找不到linuxroot 看下你的parameter

是这样的，我先把整包ok的ubuntu固件烧进去，系统正常起来，现在需要换成android的kernel，我只烧了linux-boot.img 系统起来就说找不到linuxroot，提示信息如下：

此时我再次烧入ok的kernel，从固件中解压出来的kernel，系统能正常起来。我一直没有碰parameter文件，应该是正确的。

我的观点是目前android的kernel无法正常的将initrd 文件系统引导起来，无法云心initrd系统下的init脚本，导致不能挂在真正的根文件系统。不知当初你们从android中抠出来的kernel有没有做什么修改，或者需要一些注意的地方？

/dev/block/mtd/by-name/linuxroot does not exist.

但是烧单独的内核就可以啊，文件系统一直都在，只是initrd这个引导文件系统没有把根文件系统挂载上，导致说找不到，至于为什么挂载不上，目前只有kernel的zImage不一样

使用网盘那个安卓5.1的内核，不更新的情况下找不到emmc，感觉是内核emmc驱动有问题，更新后可以找到emmc， ...

好的，感谢提醒 我试试

本人使用fireprime问题已解决，下载了wiki ubuntu区域 编译内核 里提到的单独的内核。那个和安卓sdk捆绑的 ...

现在就是有需求要把android的内核改成ubuntu可以用的内核，发现都不行。
