Can't burn signed images to emmc by uuu tool

[zohanlin]

Hello all,

MY BSP version is imx-yocto-L4.14.98_2.3.0.

I has used command to burn rootfs and signed images(uboot, zImage and uTee-6ullevk) to emmc on imx6ull,

and it worked well.

Now I try to use uuu tool to burn rootfs and signed images to emmc on imx6ull.

In " Secure boot disabled " imx6ull board, uuu can burn rootfs and signed images to emmc .

In " Secure boot enabled " imx6ull board, it would hang on as below when uuu is trying to burn image to emmc.

uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.2.91-0-g3799f4d

Success 0 Failure 0

3:13 1/ 1 [============100%============] SDP: boot -f E:\Test_IMAGE\MS57769\uuu_test\004_uuu\uuu\u-boot.imx

Could anyone tell me what happened?

Thanks,

zohan

don't suggest imx6ull use 4.14.98_2.3.0, if you want to use 4.14.98, pls try to use 4.14.98_2.0.0_ga
