mfgtool error, device disconnect

Hello forum,

 

we have to use mfgtools to burn a custom kernel,u-boot and rootfs into the board's NAND and the process can't complete because the tool keeps disconnecting the device. It doesn't report failure, but after it loads the initramfs, it starts booting from NAND after "Jumping to OS image". If we burn the vendor's image(no kernel modifications of our own), it works well, we have succeded in replacing the rootfs. If anyone can suggest a way forward?


Mfgtools 2.7
Yocto 2.1
kernel 4.1.15
u-boot 2016.03
board: Myirtech's  MYS-6ULX-IOT (nxp's imx.6ull processor)
