rm: remove write-protected regular file `kernel'?
cp: cannot create regular file `kernel': Permission denied
/home/linux/xz/A10/40_V15/android4.0/device/*/crane-evb-v13/bImage copied!
mkdir: cannot create directory `modules': Permission denied
cp: target `modules/modules' is not a directory
/home/linux/xz/A10/40_V15/android4.0/device/*/crane-evb-v13/modules copied!
chmod: cannot access `modules/modules/*': No such file or directory
-bash: ./modules/modules.mk: No such file or directory
原因是拷贝文件夹crane-evb-v13到android4.0目录下时权限没改，使用命令
sudo chmod 777 -R crane-evb-v13
后正常
