mfgtool : Waiting for /dev/utp to appear

I have a problem with my board imx6sxsabresd and BSP imx-yocto-L4.14.78_1.0.0_ga.

 

When i use ramfs provided in mfgtool package (L4.9.88_2.0.0_mfg-tool) i can program my sabresd board.

I compile mfgtool firmwares and it seems that my ramfs is not well builded.

Changing fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot by the files builded with Yocto, mfgtool stuck at this line :

Can anyone help me ?

Today i can program my sabresd board with prebuild ramfs but with my futur custom boards, it will not be possible.
