Why uboot won't start kernel when I upload bin and dts files to ram?

I copy orginal zImage-ccimx6ulstarter.bin and zImage-imx6ul-ccimx6ulstarter-id129.dtb files to uboot with command:

tftp 0x80800000 192.168.1.100:zImage-ccimx6ulstarter.bin
tftp 0x83000000 192.168.1.100:zImage-imx6ul-ccimx6ulstarter-id129.dtb

and execute

bootz 0x80800000 - 0x83000000

and files are copied properly but kernel stop response

Do the same kernel and dts boot when placed in flash partition or over tftp?
