i used virtual machine 'ubuntu 16.04' in VM15. then i do as followed：

first i built uboot config with the command "make mx6ul_14x14_evk_defconfig" ;

then  i built uboot with the command "make u-boot.imx -j16";

After compiling, some CMD files appear, and no DTB files appear；

then i built kernel config with command 'make ARCH=arm menuconfig'(The source code of the kernel is not officially provided);

then i built kernel with command 'make';

then the problem occured;

If it's a source code problem, can you provide an email, I'll send it to you, can you help me to have a look
