未解决：自行打包cpio格式的Ramdisk，与编译成功生成的kernel.bin，deviceTree一起打包成image.ub，不能正常启动kernel的问题？？？

使用开发板Z-turn Board，编译工具Petalinux，启动kernel相关打印：

非正常启动kernel:

一、打包image.ub

需要工具mkimage，文件XXX.its

确保已安装u-boot工具包，运行mkimage命令生成image.ub（FIT image），fitImage.its可仿写petalinux工程中的
fitImage-its-petalinux-user-image-plnx-zynq7-4.14-xilinx-v2018.1+gitAUTOINC+4ac76ffacb-r0-20190613030027.its： （PATH：/build/tmp/deploy/images/plnx-zynq7），确保相关文件的引用路径正确

mkimage -f fitImage.its image.ub

二、自行打包Ramdisk过程：

1、首先有编译成功的petalinux工程，取工程中已生成可用ramdisk：rootfs.cpio.gz（PATH：/images/linux）
2、新建文件夹，解压ramdisk:

gunzip rootfs.cpio.gz
cpio -idmv < rootfs.cpio.gz

3、解压后可以进入目录，根据需要做修改，再打包

我先是测试原包解压，不做任何修改，打包成rootfs.cpio.gz，最终打包入image.ub，看是否能正常加载，结果是不能正常启动kernel，打印已在最前面给出，不知是否是缺少什么步骤，望高人指点一二，万分感谢***

打包上面解压的ramdisk过程如下：
网上可搜寻到的两种方法：
a、直接通过指令打包：

find ./* | cpio -H newc -o > rootfs.cpio
gzip rootfs.cpio

b、通过脚本文件gen_initramfs_list.sh（PATH：/build/tmp/work-shared/plnx-zynq7/kernel-source/scripts）生成filelist

./gen_initramfs_list.sh /home/opt/Pzturn/ramdisk > filelist

编译源码中的gen_init_cpio.c（PATH：/build/tmp/work-shared/plnx-zynq7/kernel-source/usr）生成gen_init_cpio可执行文件

gcc -o gen_init_cpio gen_init_cpio.c

通过可执行文件gen_init_cpio链接filelist打包生成rootfs.cpio，再压缩成gzip格式

./gen_init_cpio filelist > rootfs.cpio
gzip rootfs.cpio
