Hi Team:
I want to write the images including Image、dtb、rootfs、bootloader etc files into the eMMC on the iMX8QXP-MEK by uuu mfgtool， therefore I strictly execute following documents:
（1）uuu.pdf （how to operate the uuu tool）
（2）yocto Linux User Guide.pdf （how to boot the linux and use the uuu）
（3）One training document about uuu from FAE
Excepting above documents, I execute following procedure：
（1）downloading the imx-imx8qxp-mek-images-L4.14.78_1.0.0_ga.zip from nxp website
（2）downloading the rececently uuu.exe from github
（3）connecting the PC and MEK usb type C with USB3 cable
（4）connecting the MEK debug miniUSB and PC with miniUSB cable
（5）Open the PC super-terminal
（6）Get the flash.bin、fsl-imx8qxp-mek.dtb、uramdisk-rootfs.uboot、Image etc files by decompressing (1) procedure zip file
（7）Modified the uuu.lst script file according with mfgtool script example file
（8）Power on the IMX8QXP-MEK
（9）Execute the uuu program in the windows Command windows
$uuu uuu.lst
Then, all files including the flash.bin、dtb、uramdisk rootfs、Image etc are downloaded into the iMX8QXP-MEK ddr memeory,

1:8>Okay
1:8>Start Cmd:FB: acmd ${kboot} ${loadaddr} ${initrd_addr} ${fdt_addr}
1:8>Okay
the PC supre-terminal shows following scripts：
4.996886: xhci-cdns3: USB bus 1 deregistered
Sh-4.4# Can't support > 32 dma
.5.139795] hub 1-0:1`.0: usb hub found
5.143595] hub 1-0: 1:0: 1 port detected
5.147805] xhci-cdns3: xHCI host controller
5.152195] xhci-cdns3: new USB bus registered, assigned bus
...
then above scripts always be printed (I take the picture with the attached file)
But uuu can't download the files (include mksdcard.sh.tar、Image、flash.bin、rootfs.tar.bz2、dtb files) into the eMMC
by FBK command
I don't know what's the reason, all files come from the imx-imx8qxp-mek_L4.14.78_1.0.0_ga.zip，
Could you could give me the solution？
Thank you very much
