22、【Ubuntu】 Firefly Ubuntu开发入门之（7）固化开发板上的Ubuntu系统
踩坑的过程如下：
烧Firefly-RK3288-Reload_Ubuntu14.04_201612101121.img，系统可以正常跑起来，我用git clone
https://bitbuclollipopket.org/T-Firefly/firefly-rk3288-kernel.git lollipop分支编译出来的zImage，加上Firefly-RK3288-Reload_Ubuntu14.04_201612101121.img提取出来的ramdisk，生成的boot.img烧录到板子上，系统无法启动，出现wait-for-root /dev/block/mtd/by-name/linuxroot, retry 30...。
我试过修改paramter的root参数，把/dev/block/mtd/by-name/linuxroot修改为/dev/mmcblk0p5也还是同样问题。感觉时emmc挂载不正常。请问如何修改？
另外，如果使用git clone
https://github.com/TeeFirefly/initrd.git 编译出来的initrd.img的话，系统在uboot阶段就挂了，提示sha mismatch
Hit any key to stop autoboot: 0
boot/recovery image sha mismatch!
Unable to boot:boot
try to start recovery
failed to find part:recovery
'recovery' does not seem to be a partition nor an address
Unable to boot:recovery
try to start backup
failed to find part:kernel
ERROR: [rk_load_image_from_storage]: bootrk: bad boot or kernel image
Unable to boot:backup
try to start rockusb
之后无奈的想编个android跑跑吧，把uboot、ramdisk什么之类的都替换到ubuntu上是不是就好了。于是乎编了lollipop，全部烧到了我的rk3288 reload板上，系统成功运行。。。。
接着重新把Firefly-RK3288-Reload_Ubuntu14.04_201612101121.img烧回rk3288 reload。然后做替换工作：
1、uboot替换为lollipop上编译出来的bin文件，系统能跑起来，说明我编uboot没问题；
2、从Firefly-RK3288-Reload_Ubuntu14.04_201612101121.img解压出kernel image，用lollipop上编译出来的ramdisk.img进行打包生成boot.img，
烧到板子上，系统能正常运行，说明我编译的ramdisk也没问题；
打包命令: rk_mkbootimg --kernel zImage --ramdisk ramdisk.img -o boot.img
3、将2中的ramdisk与我编译生成的kernel(zImage)打包成boot.img烧到板子上，系统只能跑到一半

跑到这里就停住了.
kernel 用的时lollipop的kernel，编译命令如下：
make firefly-rk3288-reload-linux_defconfigmake -j8 firefly-rk3288-reload-linux.img
如果使用firefly-3.14-kernel的话，系统跑到starting kernel..... 就停住了。
请各位大神帮忙看看是什么问题，谢谢！！！
